Flexbox: center horizontally and vertically
(14 answers)
Closed 2 years ago.
what I want is to center the anchor tag texts vertically also I want the "contents" div to fit the screen so that if the screen gets smaller or bigger the anchor tag doesn't run off the margin creating overflow which I don't want, I tried a bunch of different ways to fix this but none seem to work, any help is appreciated! here's the code...
$(function() {
$(".menu-link").click(function(e) {
e.preventDefault();
$(".menu-overlay").toggleClass("open");
$(".menu").toggleClass("open");
});
});
$('.menu-link').click(function() {
$('body').toggleClass('no-scroll');

You can just add display: flex; and align-items: center; to the .menu-overlay.open identifier:
$(function() {
$(".menu-link").click(function(e) {
e.preventDefault();
$(".menu-overlay").toggleClass("open");
$(".menu").toggleClass("open");
});
});
$('.menu-link').click(function() {
$('body').toggleClass('no-scroll');
});

You can easily achieve this using flexbox:
Here's the CSS to achieve what you want:
.menu-overlay.open {
position: fixed;
top: 0;
left: 0;
height: 100vh;
width: 100vw;
opacity: 1;
display: block;
z-index: 1001;
background-color: black;
overflow: hidden;
display: flex;
align-items: center;
}
.contents {
margin-left: 5%;
margin-right: 5%;
display: flex;
flex: 1;
max-width: 100%;
justify-content: space-around;
}
.contents a {
text-decoration: none;
font-family: Circular Std Book;
font-size: 30px;
color: white;
}
How do I make a full page width drop-down appear when the burger menu is clicked but still keep the close function(X). (Dropdown menu and the close burger menu transition when clicked)
Below is the JS functions for the burger menu animations. Transition with hover and close when clicked.
$("#wrapper").hover(function() {
$(".menu").toggleClass("transition");
});
$("#wrapper").click(function() {
$(".transition").toggleClass("close");
});
Below is the css to transition the burger menu when hovered and closed functions are applied.
<style>
.burgerMenu-right {
font-family: 'Circe Rounded', sans-serif;
font-weight: 800;
display: inline;
text-decoration: none;
text-transform: uppercase;
letter-spacing: 8px;
font-size: 20px;
color: black;
float: right;
position: relative;
right: 4%;
}
.main-item {
width: 30px;
height: 30px;
position: relative;
cursor: pointer;
}
.line {
position: absolute;
height: 2px;
width: 100%;
background: white;
border-radius: 2px;
transition: all cubic-bezier(0.25, 0.1, 0.28, 1.54) 0.32s;
background: black;
}
.line01 {
top: 33.3%;
width: 100%;
left: 0;
}
.line02 {
top: 66.6%;
width: 65%;
right: 0;
}
.menu:hover .line01 {
width: 65%;
}
.menu:hover .line02 {
width: 100%;
top: 66%;
}
.menu.close .line01 {
transform: rotate(45deg);
top: 49%;
width: 100%;
}
.menu.close .line02 {
transform: rotate(-45deg);
top: 49%;
width: 100%;
}
</style>
Below is the html for the burger menu....
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrapper">
<div class="main-item menu">
<span class="line line01"></span>

My #abhimanyu, #arjun, #bheem and #eklavya divs are are not appearing. Right now the unit is percentage but if I put pixels it works but it wont be responsive. Any idea why its not appearing? Thank you in advance!
Update: One more problem, on the phone when i type in the text box everything goes out of their place.
Here's my code:
function displaySignInError() {
var schoolName = document.getElementById('schoolNameBox').value.toLowerCase();
switch (schoolName) {
case 'new horizon gurukul':
window.location = "NHGLogin.php";
break;
default:
var schoolErrorMessage = document.getElementById('schoolErrorMessage');
schoolErrorMessage.innerHTML = "Please Enter a valid school name, still if invalid schoold does not exist.";
schoolErrorMessage.style.color = 'red';
}
}

You need to define parent's height since you are using percentage.
What is better to do is:
Change your HTML to:
<div class="show-this">
<div id="abhimanyu"></div>
<div id="arjun"></div>
<div id="bheem"></div>
<div id="eklavya"></div>
</div>
On your css. Add this code:
.show-this {
height: 100vh;
width: 100vw;
}
Or you can just declare
body {
height: 100vh; // or something
}
.show-this {
width: 100vw;
height: 100vh; }
.show-this #abhimanyu {
height: 10%;
width: 80%;
background: red; }
.show-this #arjun {
height: 20%;
width: 90%;
background: yellow; }
.show-this #bheem {
height: 40%;
width: 50%;
background: green; }
.show-this #eklavya {
height: 20%;
width: 100%;
background: blue; }
<div class="show-this">
<div id="abhimanyu"></div>
<div id="arjun"></div>
<div id="bheem"></div>
<div id="eklavya"></div>
</div>
Hope it helps! Cheers.
So when I used jquery to animate some padding instead of animation as if the anchor point is from the center it animates from the top left. All the code and a JSFiddle link are down below.
JSFiddle
HTML:
<div id="gaming-news-info">
<a id="news-button" style="cursor:pointer;">Go to News section</a>
</div>
CSS:
#gaming-news-info {
position: absolute;
z-index: 999;
width: 400px;
height: 200px;
top: 50%;
left: 50%;
transform: translateX(-50%) translateY(-50%);
margin-top: -100px;
}
#news-button {
background-color: #4CAF50;
border: none;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: inline-block;
font-size: 16px;
margin: 4px 2px;
cursor: pointer;
position: absolute;
margin-top: 130px;
font-family: "Prompt-SemiBold";
margin-left: 90px;
}
You do not need jquery/javascript for a simple hover effect. CSS3 transitions and transformations are perfectly capable of doing the same thing without the overhead of a script library....
#gaming-news-info {
position: absolute;
z-index: 999;
width: 400px;
height: 200px;
top: 50%;
left: 50%;
transform: translateX(-50%) translateY(-50%);
margin-top: -100px;
}
#news-button {
background-color: #4CAF50;
border: none;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: inline-block;
font-size: 16px;
margin: 4px 2px;
cursor: pointer;
position: absolute;
margin-top: 130px;
font-family: "Prompt-SemiBold";
margin-left: 90px;
transform: scale(1);
transition: all .2s;
}
#news-button:hover {
transform: scale(1.05);
transition: all .2s;
}
<div id="gaming-news-info">
<a id="news-button" style="cursor:pointer;">Go to News section</a>
</div>
I have a problem creating this effect with CSS3. I know it's possible, but i can't figure out how to do it. We created it with Javascript (https://vimeo.com/104875594). Is there anyone of you who can help with this?
The problem is that the rotation animation will run backwards when you go from left to right in the circle, because your primary position is in the top. We need it to go 360 degrees around, and not only 180 degree.
Thanks.
