I have a list of products and when i click in each product shows a popup but this popup shows in top of the page and the opacity is not in all screen.
My popup:
$('.image-sample').click(function(data)
{
var image = $(this).attr('data-image');
$.get("/sample-image/"+ image, function(data)
{
$(".popup").html('');
$(".popup").append(data);
$('.opacity').show();
$('.popup').show();
closeNews();
});
});
.popup
{
position: absolute;
width: 100%;
height: 100%;
display: none;
z-index: 1000 !important;
overflow: hidden;
}
.opacity
{
position: absolute;
width: 100%;
height: 100%;
background-color: grey;
opacity: 0.5;
z-index: 998;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="popup"></div>
<div class="opacity"></div>
It allow scroll when popup shows and shouldn't.
What i want is center the popup in screen and have the opacity in all screen.
What is my problem?
Thank you
Opacity animation issue: if you use display:none in css animation with opacity wouldnt work so i advice use in jquery not the $('.popup').show(); but fadeIn and fadeOut - $('.opacity').fadeIn(300);
Use position: fixed; not the absolute for the popup blocks (.popup, .overflow);
The scrolling you can hide toggling with jquery to the body class or style which hides overflow and setting max-height:100%;

In this stackblitz, I am not able to add animation while closing, I tried it using transform, but it didnt seem to work

Blocker is used to covering the full screen in a half-transparent mode in mobile devices

With the above code, you can have a working sidebar.
Check the working code from stackblitz

You can't animate between display:block (when .sidebar has .visible applied to it) and display:none (when .visible is removed from .sidebar).
display:none turns off the display of an element so that it has no effect on layout (the document is rendered as though the element did not exist). All descendant elements (i.e. .blocker and .content) also have their display turned off.
The reason you get an animation upon adding .visible is that .sidebar now "exists" and so .sidebar-content also exists and as such animates. As soon as you remove .visible, .sidebar ceases to exist again and so it and its descendants disappear instantaneously.
You are along the right lines using transforms but you need to remove display:none as the method for hiding the sidebar. Something like the below is a good starting point. You may need to change some values to get it looking exactly as you wish. I have added a working codepen to show the result.
.sidebar {
position: fixed;
top: 0;
left: 0;
width: 100vw;
height: 100vh;
padding: 0;
background: rgba(0, 0, 0, .5);
z-index: 99999;
transform: translateX(-100%); // new property - will move the element off the left hand side of the screen
transition: transform .5s ease-in-out; // new property - will make the sidebar slide in in a similar manner to your animation
}
.sidebar.visible {
transform: translateX(0); // new property - makes sidebar sit in its natural position (i.e. taking up the whole viewport)
}
.sidebar .blocker {
position: absolute;
width: 100%;
height: 100%;
}
.sidebar .content {
position: absolute;
top: 0;
left: 0;
background: #FFF;
height: 100%;
width: 250px;
}

<p>I want all this text to show up and it could be any length...</p>
</div>
I have two divs and one starts out hidden (with 0 width, not hidden display). When you click on the other div, I need the hidden div to slide out and push the click div out of the way as far as it needs to be pushed. The hidden div contains text that could be of variable length. In essence, I want to change the hidden div's width from 0 to auto and shift the click div over to the right by this new amount. I know you can't animate auto so I have been using the max-width trick shown here.
My problem is that the click div seems to slide out to the hidden div's new min-width but not to its actual width. Here is a fiddle of the problem: https://jsfiddle.net/tjfhzvd9/1/. Click on the red box in that fiddle to see why this is not working. I want that div to slide as far as it needs to but no farther.
I also tried doing this with Jquery.animate() but that did not work either. Your help is appreciated.
Here is a pure css solution:
HTML:
<div id="container">
<div id="div-2">
<p>I want all this text to show up ...</p>
</div>
<div id="div-1"></div>
</div>
CSS:
#container {
display: flex;
flex-direction: row;
}
#div-1 {
background-color: red;
width: 25%;
min-height: 100vh;
}
#div-2 {
background-color: blue;
width: auto;
max-width: 0;
transition: max-width 1s ease;
overflow: hidden;
}
.shown {
max-width: 75% !important;
}
JS:
$('#div-1').click(function() {
$('#div-2').toggleClass('shown');
})
CSS solution works fine but you may notice an undesirable text rendering effect. This happens because a paragraph constantly adapts it's width to the parent container's width during animation cycle. We should set a fixed width on the paragraph before running the main animation cycle:
var div2MaxWidth = 0;
// Get div2 max width
$('#div-2').css({
transitionDuration: '0s',
maxWidth: '75%', // <=== 100% - red.width
position: 'absolute',
visibility: 'hidden'
});
div2MaxWidth = $('#div-2').width();
$('#div-2').css({
maxWidth: '0',
position: 'static',
visibility: 'visible'
});
// Set fixed width to the paragraph inside div2 and restore transition's duration
$('#div-2 > p').width(div2MaxWidth + 'px');
$('#div-2').css('transitionDuration', '1s');
$('#div-1').click(function() {
$('#div-2').toggleClass('shown');
})
I have a div with position fixed (my dialog) which i give a higher z-index to takeover my page when a certain action is performed. Am trying to hide my scrollbar by doing overflow:hidden;without affecting the width of the page when the div takes over the page. Any suggestion how this would be performed??
html, body {
background: #FFFFFF;
font-family: "Avenir Medium";
height: 100%;
transition: overflow 0.37s easein-out
}
.div-dialog{
display: none;
opacity: 0;
position: fixed;
width: 0;
left: 0;
top: 0;
z-index: 0;
overflow: hidden;
background: white;
-webkit-transition: opacity 0.30s ease-in-out;
transition: opacity 0.30s easein-out;
}
Jfiddle trying to replicate my result.The implementation am trying to realize is that of myspace when you click the search icon at the top left
Was finally able to fix my problem, by doing the following
html,body{
height: 100%;
overflow: hidden;
}
body{
overflow: auto;
}
By doing this all my content stays within the body, so when an element has a position of fixed, it covers the scrollbar and its not affected by any change to its overflow,overflow:hidden or overflow:auto
I'm having trouble getting an overlay to appear on top of the visible portion of another div. The problem is, the container div has overflow, and if the user has scrolled inside that div, the overlay will not cover the scrolled portion. My question is: how can you position a div to fill the visible portion of another div using jQuery - or, alternatively, is there a way to accomplish this using just CSS?
Here is a jsFiddle demonstration, and here's the markup:
HTML
<div class="container">
<div class="overlay"></div>
<div class="content">
<p>Content here</p>
<p>Overflow content here</p>
</div>
</div>
CSS
div.container { position: absolute; height: 100px; width: 100px; overflow-y: auto; }
div.overlay { display: none; position: absolute; top: 0; left: 0; right: 0; bottom: 0; background: #F00; opacity: 0.5; }
div.content p { margin-bottom: 100px; }
and JS (load on DOM Ready)
$('div.container').click(function(){
$('div.overlay').toggle();
});
In order to achieve what you were asking for I did the following
CSS
.container {
/* setting this to relative means
overlay is positioned relative to its parent */
position: relative;
}
.overlay {
/* element taken out of normal flow */
position: absolute;
/* removed bottom and right properties otherwise
updating top property has no effect */
height: 100px;
/* When scrollbar appears width decreases to less than
100px hence having to set to 100% to allow automatic calculation */
width: 100%;
}
JavaScript
Using jQuery I now set the top property appropriately
$(".container").scroll( function( ) {
$(".overlay").css({ top: $(this).scrollTop( ) });
});
Fiddle here
Assuming you really want to cover only the visible portion:
http://jsfiddle.net/GNCaT/1/
<style type="text/css">
div.overlay {
display: none;
position: absolute;
top: 0;
left: 0;
right: 0;
height:100px; /* fixed height, set by CSS or javascript, no bottom */
background: #F00;
opacity: 0.5;
}
</style>
<script>
$('div.container').click(function(){
$('div.overlay').css('top', $('div.container').scrollTop() + 'px').toggle();
});
</script>
This will position the overlay to the top of the visible portion of the container.
You can use the DOM property scrollHeight :
$('div.container').click(function(){
$('div.overlay').css("height", this.scrollHeight).toggle();
});
http://jsfiddle.net/p6k2Z/1/
EDIT :
In order to just overlay the visible portion, you can use this :
$('div.container').click(function(){
$('div.overlay').css({
top: this.scrollTop,
height: $('div.container').css("height")})
.toggle();
});

I'm using videobox to embed streams into my site, and I just discovered that when videobox is "on"- i.e. I clicked on a link that brings it up and dims everything around it- I can still scroll down and see the rest of my (non-dimmed) site. This breaks immersion, and I'd like to disable the scrolling, but only for when the videobox is on.
I have no idea where to start though.
You can't do this just with JavaScript, as far as I know, as the onscroll event is not cancelable.
You can achieve this by positioning everything in a container div with a height and width of 100% and disabling overflow on html and body elements, so you actually get the scrollbars on the container div. When your videobox is on, you can turn on an overlay that hides everything behind it (including the scrollbars on the container) and display the videobox on top of it.
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8>

<style>
* { padding: 0; margin: 0; border: 0 }

margin: -300px 0 0 -200px;
z-index: 1001;
display: none;
}
</style>
</head>
<body>
<div id="container">
<div id="large-div"></div>
</div>
<div id="overlay"></div>
<div id="videobox-container"></div>
<script>
function showVideoBox() {
// show both overlay and videobox-container
document.getElementById("overlay").style.display = "block";
document.getElementById("videobox-container").style.display = "block";
}
showVideoBox();
</script>
</body>
</html>
(You'll have to fiddle a bit with the positions of your elements, but you get the idea.)
The easy solution is to add the css body{overflow:hidden;} when the video starts playing and after that remove it. Also, can you not put the video box in a div tag and set its position to fixed?
in videobox.js
replace line 80
this.overlay.setStyles({'top': window.getScrollTop()+'px', 'height': window.getHeight()+'px'});
with this:
this.overlay.setStyles({top:-$(window).getScroll().y,height:$(window).getScrollSize().y+$(window).getScroll().y});
Essentially this gets the height of the 'y' scroll and rather than just what the screen is showing.
