Full page overlay appears behind - javascript

I am trying to create a simple full page overlay with bootstrap.
However the overlay is appearing 'behind' my main content (a blue box in the example).
I'm sure I am missing something very obvious however any help would be appreciated.
I need to overlay to disappear when the page is clicked anywhere, this is working.
I have included my current code and a jsfiddle. You can see that the overlay is behind the blue box, which seems to load first?
HTML
<div class="overlay overlay-data">
<p>click anywhere to close this overlay</p>
</div>
<div class="col-md-4">
<div class="menu-item blue">
<p>MY INFO BOX</p>
</div>
</div>
JS
$(document).ready(function () {
$(".overlay").addClass('overlay-open');
$("section").addClass('blur');
});
$(document).on('click', '.overlay', function () {
$(".overlay").removeClass('overlay-open');
$("section").removeClass('blur');
});
CSS
.blur {
-webkit-filter: blur(2px);
}
.overlay {
position: fixed;
width: 100%;
height: 100%;
background: #000;
}
.overlay p {
text-align: center;
position: relative;
top: 20%;
height: 60%;
font-size: 80px;
}
.overlay-data {
opacity: 0;
visibility: hidden;
-webkit-transition: opacity 0.5s;
transition: opacity 0.5s;
visibility: 0s 0.5s;
transition: opacity 0.5s, visibility 0s 0.5s;
}
.overlay-open {
opacity: 0.5;
visibility: visible;
-webkit-transition: opacity 0.5s;
transition: opacity 0.5s;
}
.blue {
background: #28ABE3;
}
.menu-item {
padding-top: 45px;
padding-bottom: 45px;
margin-bottom: 45px;
transition: all 0.3s;
border: 5px solid transparent;
}

Specify the z-index in your css to be greater than your main content.
.overlay {
position: fixed;
width: 100%;
height: 100%;
background: #000;
z-index: 1;
}
JSFiddle
Read more about it at MDN, z-index.

Use z-index to add overlay effect use this css
.overlay {
position: fixed;
width: 100%;
height: 100%;
background: #000;
z-index:99999
}

How to make the button in such a way that hovering it results in the rotation and spinning of another object?

I have the following code in which the star is automatically "spinning" around the crescent and hovering it makes it "rotate". There is also a button on the left side: when it is hovered, it only changes its background-color and text-color; however, I want the star to start spinning and rotating when the button is hovered (and also want the effects of the button i.e. changing its background color and text color, to maintain simultaneously). I tried using different codes but everything I do results in messing the code up further.

How can I do that?
If I have understood the requirement correctly, you do not need Javascript for this.
However, CSS is not currently able to style a sibling element that is before a hovered element (it can't 'go back up' the DOM). But it can style a sibling element that follows the hovered element.
So the first change is to put the button element before the moon element. Now when the button element is hovered we can select its immediate sibling using the + combinator and from there we can select the rotate and moon elements to give them the animations required for rotating and spinning. (In this case we have left the definition of rotate as it is in the code in the question and introduced the spin animation to keep the star spinning around its center).
Now when the button is hovered the star rotates (moves in a large circle) and spins (rotates about its own center).
This snippet also makes the star spin when it is hovered and doesn't have any movement when there is no hovering. Obviously you can change the styling to have what you want there. Also the counterrotation is removed and the -webkit- prefixes, just to simplify things (and you don't want -webkit- with no vanilla setting set as well as some browsers may not interpret it).

CSS Transition on newly created psuedo element

I want to create a fade effect on a pseudo element but am having difficulty as i cannot use javascript on this element.
I have an example of something similar to what i am trying to do here but i cannot get the element to fade in as transitions do not seem to work when the element is created.
https://codepen.io/anon/pen/wrxPXJ
.hoverhere.dim::before {
content: '\A';
position: absolute;
width: 100%;
height:100%;
top:0;
left:0;
background:rgba(0,0,0,0.8);
opacity: 1;
transition: opacity 1s;
}
I am adding a class to a div so that the pseudo element is created after matching with the above css however cannot work out how to animate this.
I can probably get it to work without psuedo elements like below:
https://codepen.io/anon/pen/Oxwzvv
However was wondering if there is a way without changing my markup to include an empty div.
I guess you're saying you want this?
$('.hoverhere')
.mouseenter(function() { $(this).addClass('dim'); })
.mouseleave(function() { $(this).removeClass('dim'); });
.hoverhere {
width: 100%;
height: 40px;
background: red;
color: white;
text-align: center;
}
.hoverhere::before {
content: '\A';
position: absolute;
width: 20%;
height: 100%;
top: 0;
left: 0;
background: rgba(0, 0, 0, 0.8);
opacity: 0;
visibility: hidden;
transition: all 1s ease-out;
}
.hoverhere.dim::before {
opacity: 1;
visibility: visible;
transition: opacity 1s ease-out;
}
<script src="https://code.jquery.com/jquery-2.2.4.js"></script>
<p>RANDOM TEXT HERE</p>
<div class="hoverhere">HOVER ON ME</div>
<p>MORE RANDOM TEXT HERE</p>
What it needed was to have a starting point established for the opacity.
If this is just for hovering, you don't need the JS at all.
.hoverhere {
width: 100%;
height: 40px;
background: red;
color: white;
text-align: center;
}
.hoverhere::before {
content: '\A';
position: absolute;
width: 20%;
height: 100%;
top: 0;
left: 0;
background: rgba(0, 0, 0, 0.8);
opacity: 0;
visibility: hidden;
transition: all 1s ease-out;
}
.hoverhere:hover::before {
opacity: 1;
visibility: visible;
transition: opacity 1s ease-out;
}
<p>RANDOM TEXT HERE</p>
<div class="hoverhere">HOVER ON ME</div>
<p>MORE RANDOM TEXT HERE</p>

CSS Transition Width Right to Left

I am have made a heading (the word Welcome) that reveals itself once the page has loaded (onload="").
Fiddle in case the code below doesn't work.
function animate() {
document.getElementById("mainText").style.width = "100%";
}
#mainText {
margin: 0px;
display: inline-block;
font-size: 100px;
width: 0%;
transition: width 2s;
white-space: nowrap;
overflow: hidden;
text-overflow: clip;
}
<body onload="animate()">
<h1 id="mainText">Welcome</h1>
</body>
The CSS and Plain JS work fine but I want the word "Welcome" to be revealed right side first and then moving along, so from the e to the W, instead of how it currently is, which opens left to right.
I have tried text align: right;, but this doesn't change anything.
I preferably don't want to use any jQuery, if the solution is a JS one.
An example of what the desired look should be, half way though the transition:
You can use the clip-path property to clip parts of the element so they are not visible. This property can also be animated to reveal the element again, using the forwards keyword in the animation so it stays in it's 'revealed' end state.
The inset takes values that are in order: from-top, from-right, from-bottom, from-left.
#text {
margin: 0;
font-size: 100px;
animation: reveal 2s forwards;
}
#keyframes reveal {
from {
clip-path: inset(0 0 0 100%);
}
to {
clip-path: inset(0 0 0 0);
}
}
<h1 id="text">Welcome</h1>
Yes, it is possible using Transitions and Positions:
window.onload = function () {
document.querySelector("h1").classList.add("active");
};
h1 {
overflow: hidden;
display: inline-block;
position: relative;
}
h1 .mask {
position: absolute;
transition: all 0.5s linear;
left: 0;
top: 0;
bottom: 0;
right: 0;
background-color: #fff;
}
h1.active .mask {
right: 100%;
}
<h1><span class="mask"></span>Welcome</h1>
I just wrote an article about this - CSS Transitions & JavaScript for Animated Entry Effects. Hope it is useful... :)
One option is transform: translate with a pseudo element, and no extra element needed.
function animate() {
document.getElementById("mainText").classList.add('show');
}
#mainText {
position: relative;
margin: 0px;
display: inline-block;
font-size: 100px;
white-space: nowrap;
text-overflow: clip;
overflow: hidden;
}
#mainText::after {
content: '';
position: absolute;
left: 0; top: 0;
width: 100%; height: 100%;
background: white;
transition: transform 2s;
}
#mainText.show::after {
transform: translateX(-100%);
}
<body onload="animate()">
<h1 id="mainText">Welcome</h1>
</body>
Another option, an even better solution, using the pseudo with direction and left/width.
This one work in the same way clip-path does, completely transparent against its background, as opposite to having a mask that revels the text, and with much better browser support.
function animate() {
document.getElementById("mainText").classList.add('show');
}
body {
background: black;
}
#mainText {
position: relative;
margin: 0px;
display: inline-block;
font-size: 100px;
white-space: nowrap;
color: rgba(0, 0, 0, 0);
}
#mainText::before {
content: attr(data-text);
position: absolute;
left: 100%;
top: 0;
width: 0;
height: 100%;
color: white;
direction: rtl;
overflow: hidden;
transition: left 2s, width 2s;
}
#mainText.show::before {
left: 0;
width: 100%;
}
<body onload="animate()">
<h1 id="mainText" data-text="Welcome">Welcome</h1>
</body>
Something like this
function animate() {
document.getElementById("overlay").style.width = "0%";
}
#mainText {
margin: 0px;
display: inline-block;
font-size: 100px;
width: 100%;
white-space: nowrap;
overflow: hidden;
text-overflow: clip;
}
#overlay{
width: 100%;
position:absolute;
top:0;
left:0;
background:#fff;
transition: width 2s;
height:100%;
}
<body onload="animate()">
<h1 id="mainText">Welcome</h1>
<div id="overlay"></div>
</body>
This will require a pseudo-element with a background on top of your heading serving as a mask. Instead of altering the inline styles I will simply add a class is-active. So everything style related can be styled via CSS.
function animate() {
document.getElementById("mainText").className = "is-active";
}
#mainText {
margin: 0px;
display: inline-block;
position: relative;
font-size: 100px;
white-space: nowrap;
overflow: hidden;
text-overflow: clip;
}
#mainText:before {
content: '';
position: absolute;
top: 0;
left: 0;
bottom: 0;
width: 100%;
background: #FFF;
transition: width 2s;
}
#mainText.is-active:before {
width: 0%;
}
<body onload="animate()">
<h1 id="mainText">Welcome</h1>
</body>
I use Transform: translateX to achieve the desired effect.
It slides the text sideways or horizontally on the X axis.
.message {
color: darkred;
font-size: 30px;
display: inline-block;
font-weight: 100;
font-family: sans-serif;
}
.sliding-text-1,
.sliding-text-2,
.sliding-text-3 {
animation-name: slide;
animation-duration: 1s;
animation-timing-function: ease-out;
animation-iteration-count: 1;
animation-fill-mode: forwards;
opacity: 0;
}
.sliding-text-2 {
animation-delay: 2s;
color: darkblue;
}
.sliding-text-3 {
animation-delay: 4s;
color: darkgreen;
}
#keyframes slide {
from {
transform: translateX(200px);
}
to {
transform: translateX(0px);
opacity: 1;
}
}
<h1 class="message sliding-text-1">Hello!</h1>
<h1 class="message sliding-text-2">Thanks for visiting!</h1>
<h1 class="message sliding-text-3">Have a nice day!</h1>

Background Color of text field :focus

I am tryig to make nice text field, and I want when user click on it to change background color. But I want to background color slide from left to the right slowly.
It is contact form for wordpress, but I think it does not matter.
So i what I have in my CSS:
.brtel {
-webkit-transition: width 0.4s ease-in-out;
transition: width 0.4s ease-in-out;
width: 50px;
}
.brtel:focus {
border-radius: 0px;
border:none;
background:#797d7e;
color: #fff;
width: 200px;
}
Can I fix it in CSS or should I use JS?
You can do it in pure css but you need an image with the color you want as a background.
.brtel {
-webkit-transition: background-size 4s ease-in;
transition: background-size 4s ease-in;
width: 200px;
background-image: url('http://i.imgur.com/9HMnxKs.png');
background-repeat: repeat-y;
background-size: 0% 0%;
}
.brtel:focus {
border-radius: 0px;
border:none;
color: #fff;
background-size: 100% 100%;
}
see this fiddle: https://jsfiddle.net/ym7joe4L/
Edit: spelling
You can use a short code of jquery, like this
$('.animate').mouseenter(function() {
$(this).addClass('filled');
}).mouseout(function() {
$(this).removeClass('filled')
})
And manipulate the filled class by css
.animate{
display: inline-block;
height: auto!important;
width: 200px;
background: #bbb;
position: relative;
}
.animate:before {
content: '';
position: absolute;
left: 0;
top: 0;
height: 100%;
background: red;
width: 0;
transition: all .5s ease;
}
.animate.filled:before{
width: 100%;
}
input {
-webkit-transition: width 0.4s ease-in-out;
transition: width 0.4s ease-in-out;
width: 100%;
-webkit-appearance: none;
appearance: none;
background: none;
border: none;
}
HTML:
<form>
<div class="animate"><input value="Send" type="submit" class="brtel"></div>
</form>
Check this pen: http://codepen.io/todorutandrei/pen/MeKQze
I've added a transition element to your class, you can see it here https://jsfiddle.net/giuseppe_straziota/dngb5bz2/
transition: width 0.4s ease-in-out, background-color 1.5s ease;
background-color: white;
It make a background transition from white to grey, I hope it was what you desired.
You can achieve this with css only.
<form>
<button type="submit" class="brtel">Send</button>
</form>
.brtel {
position: relative;
}
.brtel:before {
position:absolute;
width: 0;
height: 50px; /* height if input field */
background-color: #666;
display: block;
transition: width .5s ease;
}
.brtel:hover:after {
width: 100%;
}
You can achieve it by CSS only.
Please check the below code.
.brtel {
width: 150px;
}
.brtel:focus {
border-radius: 0px;
border:none;
background:#797d7e;
color: #fff;
animation: equalize .4s 0s 1;

Google Material Design Growing Textarea while typing

I'm trying to implement Google Material Design Guidelines in my forms and it's working great, until I bumped into the textarea. What I want is this:
When you focus on the textarea there is only one line, but when you reach the end of the line (while typing) it automatically adds another line and continues typing there.
I have found this on codepen, but this uses an inputfield, not a textarea. This just scrolls horizontally... Demo
<input type="text" required>
Anyone who has this code and is willing to share?
Thanks
You are creating all the Material Design CSS & Jquery by yourself?
Otherwise, I found Material Design textarea like you mentioned in here:
Source: https://materializecss.com/text-inputs.html#textarea
Check out their Textarea part.
Actually, to obtain this level of control, and work around the fact that a textarea, on most web browsers, can be resized by hand, you'll want to use a div with the contenteditable attribute.
See the HTML doctor entry on contenteditable for more.
Further, to calculate font sizes and overflow, you might want to use the canvas measureText method, for example using canvas as an offscreen substitute (where you input exactly the same text that is typed inside your contenteditable element).
Finally, while the css lineHeight attribute can somewhat facilitate those calculations, there are a few javascript libraries out there that are dedicated to the purpose. I found Font.js, haven't tested it at the time of this writing.
You can use <div contentEditable> instead of textarea and that will make a trick. Also you might not use additional libraries (Material-ui, jQuery, etc.).With your code it will look like this:
.inputBlock {
position: relative;
margin-top: 20px;
