How to change the position of the div after file upload?

I want to reposition my browse button when the user uploaded a file. This is the sample of how it should really look before and after uploading the file:
Before:
After:
I change the content of my button "Browse file" to "Replace File"
This is my html code.
<div id="uploadModal" class="upload-modal">
<div class="modal-content">
<h2 style="font-size: 24px;">Choose file</h2>
<p>
Choose the csv file containing the data you want to create a forecast for.
</p>
<div class="browse-file">
<div id="filename"></div>
<input type="file" id="file-upload" multiple required />
<label for="file-upload">Browse file</label>
</div>
<div class="options">
<button class="cancel"><h4>Cancel</h4></button>
<button class="proceed"><h4>Proceed</h4></button>
</div>
</div>
</div>
Here is my CSS
.upload-modal {
display: none;
position: fixed;
padding-top: 100px;
left: 0;
top: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 34, 2, 0.3);
}
input[type="file"] {
position: absolute;
opacity: 0;
z-index: -1;
}
input + label {
padding: 10px 24px;
background: #D4E8CF;
border-radius: 100px;
position: static;
width: 119px;
height: 40px;
border: none;
cursor: pointer;
z-index: 1;
}
#filename{
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
max-width: 100px;
justify-content: left;
align-items: flex-start;
}
What's happening here is that my button moves according to the length of the file so I added max-width but no luck. Thanks!
EDIT: I added css for upload-modal

I'm not sure you need to use absolute positioning for what you want.
You could set div#upload-modal or div.modal-content to position: relative;
and then position the button element with left: or right: or use float: right;
https://developer.mozilla.org/en-US/docs/Web/CSS/position
https://developer.mozilla.org/en-US/docs/Web/CSS/float

This alternate version uses CSS's Flexbox and JavaScript's Event Listeners.
It probably doesn't do precisely what you want but should come close enough that reading through the comments a few times and playing around with the code should make clear how you can get to where you want to go using just a few lines of JavaScript to grab the file name and show it on the screen.
MDN (linked above) is a great place to get more clarity about any particular front-end feature that you're interested in using. Happy coding!
// Unnamed function runs as soon as the DOM elements are ready
window.addEventListener('DOMContentLoaded', () => {
// Identifies some of the DOM elements
const
filenameSpan = document.getElementById("filename-span"),
fileInput = document.getElementById("file-input"),
chooseBtn = document.getElementById("choose-btn");
// When the input changes (when a file is chosen), calls `updateDisplay`
fileInput.addEventListener("change", updateDisplay);
// Defines `updateDisplay`
function updateDisplay(){
// Puts first fiename in span and "unhides" it
const filename = fileInput.files[0]?.name;
filenameSpan.textContent = filename || "(choose file)";
filenameSpan.classList.remove("hidden");
};

How do I make a responsive grid consisting of square images?

On my website, I would like to add a grid consisting of square images (album covers). I also want to add this hover effect to said images: https://codepen.io/jarvis-ai/pen/GRJpQWO. How would I do this?
I have already tried a couple of things I found while researching my question but I never got the result I wanted. I have always had issues with the sizing of the images and making the sizes responsive. Here is a visualization of what I want it to look like and what I to happen:
Grid on a normal-sized monitor:
Grid on a smaller monitor or window:
Image on hover:
Pretty much: If the page is viewed on a normal-sized monitor, there should be 4 images in one row. If the page is viewed on a phone or if the window is resized, the images split into more rows with one row containing less than 4 now. If the mouse is being hovered over an image, the image should do the effect thing.
Notice: I should be able to do the hover effect by myself since there is already a working demo. I am just mentioning that I want the effect so that you can give me a solution that works with the effect.
Here is the last thing I have tried:
:root {
--grey: grey;
--white: white;
}
#music {
width: 100%;
min-height: 100vh;
background-color: var(--grey);
display: flex;
color: var(--white);
justify-content: center;
align-items: center;
text-align: center;
flex-direction: column;
}
#cover-section {
display: flex;
align-items: center;
vertical-align: middle;
justify-content: center;
flex-direction: row;
}
.cover {
flex: 1 0 21%;
width: 100%;
height: auto;
background-image: url(https://commons.wikimedia.org/wiki/File:Stack_Overflow_icon.svg);
}
<div id="music">
<div id="cover-section">
<div class="cover"></div>
<div class="cover"></div>
<div class="cover"></div>
<div class="cover"></div>
<div class="cover"></div>
<div class="cover"></div>
<div class="cover"></div>
<div class="cover"></div>
<div class="cover"></div>
</div>
</div>
Thanks in advance for your help!
By the way: If I need JavaScript to achieve this, please do not tell me to just use JavaScript but give me some code I could use, as I have done next to nothing with JavaScript before.

Something that works is that.
I cant implement all the part you want, but for use this example in a mobile view use the media-query css.
Something to start, not a definitive solution! It would be expensive to do it all here.

</html>

I managed to figure out a solution by myself. Here is the code:
HTML:
<div id="music">
<div id="cover-section">
<div class="cover">
<!--Cover-->
</div>
<div class="cover">
<!--Cover-->
</div>
<div class="cover">
<!--Cover-->
</div>
<div class="cover">
<!--Cover-->
</div>
<div class="cover">
<!--Cover-->
</div>
<div class="cover">
<!--Cover-->
</div>
<div class="cover">
<!--Cover-->
</div>
<div class="cover">
<!--Cover-->
</div>
<div class="cover" id="tablet-cover">
<!--Cover-->
</div>
</div>
</div>
The tablet cover does not actually exist and is just a placeholder in case there are an uneven amount of squares in one row. As you can see in the...
CSS:
#music {
width: 100%;
min-height: 100vh;
background-color: var(--grey);
display: flex;
color: var(--white);
justify-content: center;
align-items: center;
text-align: center;
flex-direction: column;
}
#cover-section {
display: flex;
flex-wrap: wrap;
width: 80%;
}
.cover {
margin: 0px;
flex: 1 0 21%;
background-color: blue;
border: 2px solid black;
}
#tablet-cover {
display: none;
}
#media only screen and (max-width: 768px) {
/* For phones: */
.cover {
flex: 1 0 41%;
}
#waving-hand span {
font-size: 30pt;
}
}
#media only screen and (min-width: 600px) and (max-width: 800px) {
/* For tablets: */
.cover {
flex: 1 0 31%;
}
#tablet-cover {
display: block;
}
#waving-hand span {
font-size: 70pt;
}
}
The tablet cover is being removed on smaller or larger screens, where there would be an even number of squares in one row. It gets added once there is an uneven amount of covers in a row so that the last row has two squares instead of two rectangles.
Now for the self-engineered JavaScript code:
let coverWidth = document.querySelector('.cover').offsetWidth;
const allCovers = document.getElementsByClassName('cover')
for (var i = 0; i < allCovers.length ; i++){
allCovers[i].style.height= coverWidth + "px";
}
function coverheight(){
let coverWidth = document.querySelector('.cover').offsetWidth;
const allCovers = document.getElementsByClassName('cover')
for (var i = 0; i < allCovers.length ; i++){
allCovers[i].style.height= coverWidth + "px";
}
}
window.onresize = coverheight;
This is what the code basically does:
Check the width of the divs and then apply the value of the div-width to the height attribute of the divs
Every time the screen is resized, it re-checks the values and sets the new values accordingly
I do not know if this code is the "cleanest" code, but as long as it works, I am happy. What sucks to me is that I had to work with media queries, because the flex layout is usually used for when you want a layout that is responsible by default, AFAIK.
Thanks to everyone who tried helping me out though! I hope I can help someone else with my spaghetti code.

Is there a way to jump from a section into another section with Vanilla JavaScript?

I have two sections one over the other.
What I want to do is that when I click the button, the first section display: none with a small transition and the second one appears. I need to do that with vanilla JavaScript as I'm learning it.
My goal is to be able to create a login when the password is entered, the person is moved to the second section. (this is just for Front end, nothing backend).
Here is the code below:
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
/* Login Background */
#first{
position: absolute;
width: 100%;
height: 100vh;
background-color: #464159;
z-index: 1;
}
/* Login */
.login-container{
position: absolute;
top: 50%;
right: 50%;
transform: translate(50%, -100%);
display: flex;
align-items: center;
justify-content: center;
}
.logo{
justify-content: center;
margin-right: 20px;
}
.logo img{
width: 180px;
height: auto;
}
.user{
display: flex;
flex-direction: column;
}
.w8u{
color: white;
font-size: 15px;
margin: 0 0 10px 0;
}
.submit{
flex: 1;
margin: 30px 0 0 10px;
}
/* Menu */
#second{
position: absolute;
width: 100%;
height: 100vh;
background-color: orangered;
z-index: -1;
}
<body>
<section id="first">
<div class="login-container">
<!-- Logo User -->
<div class="logo">
<img src="w-logo.jpg" alt="User">
</div>
<!-- User Name -->
<div class="user">
<div class="w8u">
<h3>User</h3>
</div>
<div>
<input class="input" type="password" placeholder="Enter your password" required>
</div>
</div>
<!-- Submit Button -->
<button id="btn-submit" class="submit" type="submit" onclick="">GO!</button>
</section>
<section id="second">
</section>
<script src="app.js"></script>
</body>

Yes, you can change CSS of elements using JavaScript:
function login(){
document.getElementById("first").style.display="none";
document.getElementById("second").style.display="block";
}
*{
margin: 0;
padding: 0;
box-sizing: border-box;
}
/* Login Background */
#first{
position: absolute;
width: 100%;
height: 100vh;
background-color: #464159;
z-index: 1;
}
/* Login */
.login-container{
position: absolute;
top: 50%;
right: 50%;
transform: translate(50%, -100%);
display: flex;
align-items: center;
justify-content: center;
}
.logo{
justify-content: center;
margin-right: 20px;
}
.logo img{
width: 180px;
height: auto;
}
.user{
display: flex;
flex-direction: column;
}
.w8u{
color: white;
font-size: 15px;
margin: 0 0 10px 0;
}
.submit{
flex: 1;
margin: 30px 0 0 10px;
}
/* Menu */
#second{
position: absolute;
width: 100%;
height: 100vh;
background-color: orangered;
z-index: -1;
}
<body>
<section id="first">
<div class="login-container">
<!-- Logo User -->
<div class="logo">
<img src="w-logo.jpg" alt="User">
</div>
<!-- User Name -->
<div class="user">
<div class="w8u">
<h3>User</h3>
</div>
<div>
<input class="input" type="password" placeholder="Enter your password" required>
</div>
</div>
<!-- Submit Button -->
<button id="btn-submit" class="submit" type="submit" onclick="login()">GO!</button>
</section>
<section id="second">
Section 2
</section>
<script>
</script>
</body>

Short Answer:
You can solve your issue by using a common pattern of styling transitions and toggling classes in JavaScript.
/* Get Screen Container */
let context = document.querySelector("main.screen-container");
/* Helper Methods */
// Utility
const ele = context.querySelector.bind(context),
eles = context.querySelectorAll.bind(context);
// Action
const showScreen = inactiveScreen => {
const screens = eles(".screen");
screens.forEach(screen => screen.classList.remove("active-screen"));
inactiveScreen.classList.add("active-screen");
}
// Elements
const login_button = ele("#loginBtn"),
logout_button = ele("#logoutBtn"),
login_screen = ele("#login"),
loggedIn_screen = ele("#loggedIn");
// Add Event Listeners and Handlers
login_button.addEventListener("click", () => showScreen(loggedIn_screen));
logout_button.addEventListener("click", () => showScreen(login_screen));

Explanation of Answer:
In your question you're asking for help in the following:
Using Sections as Different Screens in an Application
Change Screens on an Event such as click
Transition between Screens when the Screen Changes
Something like this isn't an atypical need and, in fact, just looking at the above you can see the resemblance between what you're looking for and common things like a carousel or tab navigation.
Since this is the case there is a pretty common pattern when designing markup based around these types of requirements and this pattern is used in frameworks like BootStrap, DataTables, JQuery, etc.
The Mark-Up Pattern:
Create a Container
Provide a class to define this type of container ( screen-container )
Create Visual Elements
In your case Section Elements dubbed Screens
Provide a class to define these specific elements
In your case something like screen
You will likely also want to provide an ID for each of these Visual Elements based on their Content.
In your case something like login and loggedIn
Create a class that will serve as the active Visual Element
In your case something like active-screen
Incorporating the above you end up with a basic outline:
<main class="screen-container">
<section id="login" class="screen active-screen"></section>
<section id="loggedIn" class="screen"></section>
</main>
Example:
html, body, main, .screen-container {
height: 100%;
width: 100%;
}
.screen-container
.screen {
padding: 3px;
background: rgba(24,24,24, .3);
border: 3px solid black;
width: 100px;
height: 100px;
}
.screen-container
.screen.active-screen {
border-color: green;
}
<main class="screen-container">
<section id="login" class="screen active-screen">login</section>
<section id="loggedIn" class="screen">logged in</section>
</main>
Styling:
In your initial question you say that you want to use the display property to hide and show your screens, however, you also state that you would like to have the screens transition from one to another.
Transitioning is definitely possible through the aptly named CSS transition property ( More info on MDN ).
The problem is that the display property is not able to be animated. If an element is configured to display: none; the page is immediately repainted with that element removed.
This means that you need to use a different property, and we typically would use opacity or visibility. Here are the differences between these three:
display: none;
immediately collapses the element
removes the element from view.
There's no transition allowed.
visibility: hidden;
Does not collapse the element
The space it occupied is blank.
removes the element from view
Transitions are allowed
The element will still pop out of sight.
opacity: 0;
Does not collapse the element
The space it occupied is blank.
removes the element from view
Transitions are allowed.
The element will fade until it is not visible.
Here is an example of the different way these properties affect the layout of the page:
const context = document.querySelector("#examples");
const ele = context.querySelector.bind(context),
hide = section => section.classList.toggle("hide"),
onClickHide = (btn, section) => btn.addEventListener("click", () => hide(section));
opacity = ele(".opacity"),
opacity_button = ele("#oBtn"),
visibility = ele(".visibility"),
visibility_button = ele("#vBtn"),
display = ele(".display"),
display_button = ele("#dBtn"),
toggle_button = ele("#tBtn");
onClickHide(opacity_button, opacity);
onClickHide(visibility_button, visibility);
onClickHide(display_button, display);
toggle_button
.addEventListener("click", function() {
hide(opacity);
hide(visibility);
hide(display);
});
html,
body,
#examples {
width: 100%;
height: 100%;
box-sizing: content-box;
margin: 0px;
padding: 0px;
}
#examples section {
display: flex;
flex-direction: column;
width: 100px;
height: 100px;
border: 5px solid black;
margin: 5px;
transition: all .5s ease-in-out;
}
#examples section.hide {
border-radius: 100px;
}
#examples section.opacity {
background-color: blue;
color: white;
}
#examples section.opacity.hide {
opacity: 0;
}
#examples section.visibility {
background-color: purple;
color: white;
}
#examples section.visibility.hide {
visibility: hidden;
}
#examples section.display {
display: block;
background-color: red;
color: white;
}
#examples section.display.hide {
color: black;
display: none;
}
<main id="examples">
<section class="opacity">opacity <button id="oBtn">hide</button></section>
<hr />
<section class="visibility">visibility <button id="vBtn">hide</button></section>
<hr />
<section class="display">display <button id="dBtn">hide</button></section>
<hr/>
<button id="tBtn">Toggle All</button>
</main>
Note: In the above there are actually two properties transitioning - opacity, visibility, or display - and border-radius. You should notice firstly how in the display example the border-radius change isn't seen at all, and secondly how the display example is the only one that collapses the element so that it no longer takes up space.
Applying Transitions:
By combining opacity: 0; with height: 0px; width: 0px; we can remove the element visually from the page while also removing any impact it has on other elements - meaning that it won't take up space and is transitionable.
setInterval(function() {
const screens = [
document.querySelector(".screen.active-screen"),
document.querySelector(".screen:not(.active-screen)")
];
screens[0].classList.toggle("active-screen");
screens[0].ontransitionend = () => {
screens[1].classList.toggle("active-screen");
screens[0].ontransitionend = undefined;
}
}, 1000)
html,
body,
main,
.screen-container {
height: 100%;
width: 100%;
}
.screen-container .screen {
transition: all .3s ease-in-out;
opacity: 0;
height: 0px;
width: 0px;
}
.screen-container .screen.active-screen {
background: rgba(24, 24, 24, .3);
border: 3px solid black;
padding: 3px;
border-color: green;
width: 100px;
height: 100px;
opacity: 1;
}
<main class="screen-container">
<section id="login" class="screen active-screen">login</section>
<section id="loggedIn" class="screen">logged in</section>
</main>
JavaScript
The final piece of the puzzle is the JavaScript mechanics of the Screens.
Any Programmer wants to make the switch as easy as possible, and this is done typically by providing a function that allows for quick reassignment of the class active-screen by removing it from the current active screen and applying it to the desired visual element.
One thing to take into account is that you want your queries for elements to be as specific as possible. Meaning that instead of document.querySelector you want to provide the smallest context of where to find your Visual Elements. a.e.
/* Get Screen Container */
let context = document.querySelector("main.screen-container");
/* Helper Methods */
// Utility
const ele = context.querySelector.bind(context),
eles = context.querySelectorAll.bind(context);
This prevents code collision where other code in your Application's JavaScript, Styling, or Mark-Up may utilize a screen or active-screen class that isn't relevant to what you're doing here.
Note: This is actually a problem in BootStrap currently. It searches for the active class in it's Tab architecture. This is such a generic class name that other libraries utilize it and it can cause a giant headache to get things to work properly. Writing explicit patching because you didn't think through your design fully is something I'd just as soon spare you from, so try to keep interactivity with other code in mind.
Lastly we write our function ( showScreen ) that allow for quick, easy switching between screens:
// Action
const showScreen = inactiveScreen => {
const screens = eles(".screen");
screens.forEach(screen => screen.classList.remove("active-screen"));
inactiveScreen.classList.add("active-screen");
}
And believe it or not, that's pretty much it!
All that's left to do is apply this functionality to your button click events and it works just as it should:
Result:
/* Get Screen Container */
let context = document.querySelector("main.screen-container");
/* Helper Methods */
// Utility
const ele = context.querySelector.bind(context),
eles = context.querySelectorAll.bind(context);
// Action
const showScreen = inactiveScreen => {
const screens = eles(".screen");
screens.forEach(screen => screen.classList.remove("active-screen"));
inactiveScreen.classList.add("active-screen");
}
// Elements
const login_button = ele("#loginBtn"),
logout_button = ele("#logoutBtn"),
login_screen = ele("#login"),
loggedIn_screen = ele("#loggedIn");
// Add Event Listeners and Handlers
login_button.addEventListener("click", () => showScreen(loggedIn_screen));
logout_button.addEventListener("click", () => showScreen(login_screen));

Dot leaders with picture background

So I'm building a website for a restaurant and I'm in a pickle. I'm trying to create the menu there. The idea is to align the food name to the left, the price to the right and fill the gap between them with dots. Like this
Hamburger ............................................ $ 4.00
XXL Hamburger .................................... $ 4.00
Milkshake .............................................. $ 4.00
I found a couple of solutions, which only work if you have a background with one color and no texture. The idea was to fill the whole line with dots and set the name/price background span with the same color as the site background, so the dots wouldn't show. But I have a picture for the background.
I'm not going to post my code here, because it wouldn't really matter or help.
Is it even possible? Doesn't have to be css only, might as well be done with JavaScript.

I am kinda late, but you can quite easily do it with a radial-gradient:
.col {
display: inline-block;
vertical-align: top;
}
.names span {
width: 200px;
display: flex;
}
.prices span {
display: block;
text-align:right;
}
.names span:after {
content: "";
display: inline-block;
height: 1em;
flex-grow: 1;
background: radial-gradient(black 25%, transparent 25%) scroll repeat-x bottom left/5px 5px;
}
<div class='names col'>
<span>Hamburger</span>
<span>Hot Dogs</span>
<span>Superman Hamburger</span>
</div>
<div class='prices col'>
<span>$1.00</span>
<span>$0.50</span>
<span>$400.00</span>
</div>
JSFiddle Demo

It's easy to do with some simple javascript and css, here's a fiddle: jsfiddle
The key is to set the width of the div that holds the dots to the width of the column minus the width of the food name minus the width of the price, and to make sure there are more than enough dots to cover the distance, and to set overflow: hidden for the dot div.
$(".menu-row").each(function(index, element) {
var menuRowWidth = $(element).width();
var foodItemWidth = $(element).children('.food-item').width();
var priceWidth = $(element).children('.price').width();
var $dotFiller = $(element).children('.dot-filler');
var dotFillerWidth = menuRowWidth - foodItemWidth - priceWidth;
$dotFiller.width(dotFillerWidth + "px");
});
Then float the item and dot div left, the price right, all within a set width column. It's also important that overflow: hidden is set for the dots, because when we set the width of that div in javascript we want all extra dots to just be cut off. The CSS:
.food-item {
float: left
}
.dot-filler {
overflow: hidden;
width: 0;
float: left;
}
.price {
float: right;
}
.menu-row {
width: 400px;
}
Then structure your html as follows:
<div class="menu-row">
<div class="food-item">Steak</div>
<div class="dot-filler">............................................................................................</div>
<div class="price">$18.00</div>
</div>
<div class="menu-row">
<div class="food-item">Hamburger</div>
<div class="dot-filler">............................................................................................</div>
<div class="price">$8.00</div>
</div>

You can use a wrapper to set a fix width of your Name + Dots.
The css will look like this:
.wrapper {
width: 300px;
overflow: hidden;
display: inline-block;;
white-space: nowrap;
}
The HTML like this:
<div>
<ul class="noDisc">
<li>
<div class="wrapper">
<span>HAMBURGER </span>
<span>...............................................................</span>
</div>
<span>$ 40.00</span>
</li>
<li>
<div class="wrapper">
<span>FRIED CHIKEN </span>
<span>...............................................................</span>
</div>
<span>$ 13.00</span>
</li>
<li>
<div class="wrapper">
<span>STEAK ON A STICK </span>
<span>...............................................................</span>
</div>
<span>$ 99.00</span>
</li>
</ul>
</div>
Live sample:
fiddle

Use display:table; and display: table-cell; for the divs inside the list-elements and border-bottom: Xpx dotted black; for the dots.
ul{
margin: 0;
padding: 0;
}
ul li{
display: table;
width: 100%;
}
ul li div {
display: table-cell;
}
ul li div.food {
padding-right: 5px;
}
ul li div.dots {
border-bottom: 1px dotted #000;
width: 100%;
position: relative;
top: -4px;
}
ul li div.price {
padding-left: 5px;
}
<ul>
<li>
<div class="food">Spaghetti</div>
<div class="dots"> </div>
<div class="price">10.00$</div>
</li>
<li>
<div class="food">Spaghetti</div>
<div class="dots"></div>
<div class="price">10.00$</div>
</li>
<li>
<div class="food">Spaghetti</div>
<div class="dots"></div>
<div class="price">10.00$</div>
</li>
</ul>

Thanks. I used what you had here and improved on it. This code is meant for woocommerce product items, but can be edited for whatever you need. $containerElement is the element you are measuring the width of.
/**
* dotFiller
* adds dynamic dot leaders between product title and count element (<mark>)
* #return void
*/
var dotFiller = function(){
var $containerElement = $('ul.products li.product.has-children h2'),
df = '<div class="df">.....................................................................</div>';
$containerElement.each(function(i,el){
var $el = $(el),
w = $el.width(),
mw = $el.find('mark').width(),
tw = $el.find('span').width(),
dfw = (w - mw - tw) - 24;
// if its not there, lets add it
if (!$(el).has('.df').length){
$el.find('span').after(df);
}
$el.find('.df').css('width',dfw + "px");
});
};
dotFiller();
With this code, you can update/ recalculate on resize like so :
$('window').on('resize',function(){ dotFiller(); });
And here is my css for the internal elements:
mark {
background-color: transparent;
color: $secondary;
display: inline-block; float: right;
font-weight: normal;
}
div.df {
overflow: hidden;
display: inline-block;
margin-left: 10px;
position: relative;
top: 2px;
font-weight: normal;
opacity: 0.8;
}
I hope this helps someone!

Use a div that has a flex spacer with a border-bottom to achieve easy leader dots... The flex layout seems to be the most elegant solution. No pseudo-elements, or left and right block display, etc... Very simple...

How to align text inside a circle dynamically?

I have a div with some random text.I have designed the div as a circle. I want to align the text inside the circle in the center. I can do this manually i mean for a static text i can do this. I want to know if there is any way to do this dynamically. I want to create the circle depending on the text size automatically and positioned the text in the center and aligned.
I have the code here :
<html>
<head>
<title>Test</title>
</head>
<body>
<section class="main">
<div id="greeting">
<p>Hi, This is the greeting part of my site.</p>
</div>
</section>
</body>
</html>
Thank you.

You can use
#greeting{
display: flex;
justify-content: center;
align-items: center;
}
How it works:
justify-content defines where flex items will align according to the main axis (horizontally in our case)
align-items does the same with the axis perpendicular to the main one (vertically in our case).
It works for any element, and it's probably the easiest and shortest way to center something horizontally and vertically

I have solved the problem after doing a lot of searching. I got my one and only clue from here :
Then I have tried a lot of time and finally I have done it. Here is the javascript code:
<script type="text/javascript">
var gr = $('#gr').width();
var grt = $('#greeting').width();
//alert(grt/2.5 >=gr);
if((grt/2.5)>=gr)
{
$('#gr').css({'height':gr+'px'});
}
else{
$('#greeting').css({'width':gr*2.5+'px'});
$('#greeting').css({'height':gr*2.5+'px'});
}
</script>
Here is the HTML code:
<div id="greeting">
<p id="gr">
Hi there this is my greeting part.
</p>
</div>
finally here is the CSS part:
#greeting{
color: #F8F8F8;
margin:5px;
width:0px;
border-radius: 50%;
background-color: #F99793;
text-align: center;
display: flex;
justify-content: center;
align-items: center;
}
#gr{
isplay: flex;
justify-content: center;
align-items: center;
word-wrap:break-word;
}
You can check this out in here.

Easy - use transform. This is CSS3 and remember to prefix the transform property (-webkit-, etc).
Fiddle for you
#greeting{
position: relative;
height:450px;
width:450px;
border-radius: 50%;
background-color: #779EC6;
text-align: center;
}
p {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%);
}

HTML:
<section class="main">
<div id="greeting">
<p>Hi, This is the greeting part of my site.</p>
</div>
</section>
CSS:
section.main{
display: table;
border: 2px solid #999;
height: 200px;
width: 200px;
background-color: #ccc;
border-radius: 50%;
padding: 7rem;
}
section.main > #greeting{
display: table-cell;
text-align: center;
vertical-align: middle
}
FIDDLE: http://jsfiddle.net/y3699smx/

Set section with class main to display:table; and give display: table-cell; and vertical-align: middle; style to #greeting. If text size will increase in this code, alignment will get adjust accordingly.
