I'm using the following code.
By clicking on div id="popUpPane", the div and it's childs should appear and slowly fade in.
By clicking on the div again, it should slowly fade out and then disappear.
Firefox and Chrome (which is webkit too) behave that way and I know Safari did in an earlier version, too. But right know on Safari and on Safari Mobile nothing happens at all when I click on "popUpPane".
Is this a bug in Safari or is there something I could change to come back to the intended behaviour?
One addition: If I set -webkit-transition to -webkit-transition: opacity .5s ease-in-out; it works fine but the transition only appears on the first click. There's no transitions after that first one... If I delete the opacity-part in the java-script the opo-up works but there's no transition.
All other transitions on my site are working. But they all use only opacity and no visibility.
Here's my code:
CSS:
#popUpPane {
white-space:normal;
position:fixed;
width:100%;
height:100%;
top:0;
left:0;
text-align:center;
vertical-align:middle;
visibility:hidden;
z-index:90;
}
#greyOut {
position:fixed;
width:100%;
height:100%;
top:0;
left:0;
background-color:#000;
opacity:0;
}
#popUpPicCanvas {
position:relative;
top:50%;
margin-top:-325px;
display:inline;
opacity:0;
z-index:100;
}
.fade {
-webkit-transition: all .5s ease-in-out;
-moz-transition: all .5s ease-in-out;
-o-transition: all .5s ease-in-out;
transition: all .5s ease-in-out;
}
HTML:
<div id="popUpPane" onClick="noPopUp()">
<div id="greyOut" class="fade"> </div>
<canvas id="popUpPicCanvas" width="1000" height="650" title="Bastian Beuttel" class="fade"></canvas>
</div>
Javascript:
var popUpPane = document.getElementById("popUpPane"),
greyOut = document.getElementById("greyOut"),
popUpPicCanvas = document.getElementById("popUpPicCanvas"),
popCanvasContext = popUpPicCanvas.getContext("2d");
var doPopUp = function(source,x,y){
var popUpPic = document.getElementById("pic"+source);
popCanvasContext.canvas.width = x;
popCanvasContext.canvas.height = y;
popCanvasContext.drawImage(popUpPic, 0, 0,x,y);
popUpPane.style.visibility = "visible";
greyOut.style.opacity = "0.7";
popUpPicCanvas.style.opacity = "1";
};
var noPopUp = function(){
greyOut.style.opacity = "0";
popUpPicCanvas.style.opacity = "0";
popUpPane.style.visibility = "hidden";
};
I hope someone can help me.
Thanks for your responds!
Yep, there is a bug in mobile Safari with simultaneous transition for opacity+visibility.
You can fix it using something except for visibility: in your case setting the width and height to 0 would help. However you must add the delay, so they would change not instantly.
Here is a dabblet with the working example: http://dabblet.com/gist/1642110
/**
* Delayed alternative for visibility
*/
a {
display: inline-block;
background: #888;
color:#FFF;
padding: 1em;
}
div {
width: 100px;
height: 100px;
background: lime;
transition: opacity 1s;
}
a:hover+div {
width: 0;
height: 0;
opacity: 0;
transition: width 0s 1s, height 0s 1s, opacity 1s;
}
Thank you!
Since this bug is now removed from the latest releases of webkit the problem is gone for safari and chrome.
i started to have problems since the position of my div also was transitioned so I wrote it like this:
.dofade {
-webkit-transition: visibility .5s ease-in-out, opacity .5s ease-in-out;
-moz-transition: visibility .5s ease-in-out, opacity .5s ease-in-out;
-o-transition: visibility .5s ease-in-out, opacity .5s ease-in-out;
transition: visibility .5s ease-in-out, opacity .5s ease-in-out;
}

I want to change my images with javascript and add an fade effect.
This is my css for the fade effect:
var image=document.getElementById("image");
var currentPos = 0;
var images = ["foto1.jpg","foto2.jpg","foto3.jpg"]
function volgendefoto() {
if (++currentPos >= images.length) currentPos = 0;
image.src = images[currentPos];
}
setInterval(volgendefoto, 4100);
#map {
height:1000px;
width:1000px;
background:black;
}
#overlay {
z-index:2;
background:white;
height:1000px;
width:1000px;
opacity:0;
-webkit-transition: opacity 0.1s;
-ms-transition: opacity 0.1s;
-moz-transition: opacity 0.1s;
-o-transition: opacity 0.1s;
transition: opacity 1s;
margin-top:-1000px;
transition-delay: 0.1s;
-webkit-transition-delay: 0.1s;
}
#overlay:hover {
opacity:.8;
transition-delay: 0s;
-webkit-transition-delay: 0s;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='map'>
<img id="image" src="foto1.jpg">
<div id='overlay'></div>
</div>
It is for a school project where we are making a responsive website, so I am going to add this to that site.
Tried your piece of code which gives fade-out effect for the image on hover.
[You can see the output below][1]
[1]: https://jsfiddle.net/cxLjLnu8/1/ "Output here"
Is this what you did and expected?
Which effect you are in need of fade-in
or fade-out?
and
do you need the effect on Hover or on sliding the images?
i have this following jsfiddle link
where am trying to squeeze the webpage to show an AD towards right
http://jsfiddle.net/azgjr8k0/
Works well with responsive sites, but in the above given fiddle link. it doesn't squeeze a div with fixed width & non responsive sites.
any way i can do it then let me know
here is the css
#test {
position:fixed;
width:160px;
background:blue;
right:-160px;
top:0px;
bottom:0px;
-webkit-transition: all ease-in-out 1s;
-moz-transition: all ease-in-out 1s;
transition: all ease-in-out 1s;
}
#test.show {
right:0;
}
#container{
margin-right:0;
-webkit-transition: all ease-in-out 1s;
-moz-transition: all ease-in-out 1s;
transition: all ease-in-out 1s;
}
#container.squeezed {
margin-right:160px;
}
javscript/jquery code
window.onscroll = function () {
if (pageYOffset > 100) {
$("#test").addClass("show");
$("#container").addClass("squeezed");
} else if (pageYOffset < 100) {
$("#test").removeClass("show");
$("#container").removeClass("squeezed");
}
}
Here is the solution:

If you want to set widths on things but have them be responsive, make sure they're set as the max-width.
#box{
width: 100%;
max-width:500px;
}
I've been experimenting with Ace Editor and I've been trying to automatically "hide" (= not use the system defaults) the vertical/horizontal scrollbars, when not in use.
Is there a way? Any ideas?
Just add overflow:auto css to the right element. I think that could be .ace_scroller. Give me example with scrollers or find by yourself using Object Inspector (Ctrl + Shift + I ; Chrome, FF, Opera).
Edit:
There is your code:
body .ace_scrollbar-v {
overflow-y: auto;
}
body .ace_scrollbar-h {
overflow-x: auto;
}
Edit2:
Hide scrollbar If editor isn't hovered:
body .ace_scrollbar {
display: none;
}
body .ace_editor:hover .ace_scrollbar {
display: block;
}
Or with animation:
body .ace_scrollbar {
-webkit-transition: opacity .3s ease-in-out;
-moz-transition: opacity .3s ease-in-out;
-ms-transition: opacity .3s ease-in-out;
-o-transition: opacity .3s ease-in-out;
transition: opacity .3s ease-in-out;
opacity: 0;
}
body .ace_editor:hover .ace_scrollbar {
opacity: 1;
}
You may want to set the word wrap too.
editor.getSession().setUseWrapMode(true)
I have an img tag that I want to change the src when hover and it all works but i would like to add some transition so it doesn't look so rough but since it's an img src i cant target it with css.
http://jsfiddle.net/Ne5zw/1/
html
<img id="bg" src="img/img1.jpg">
<div onmouseover="imgChange('img/img2.jpg'); "onmouseout="imgChange('img/img1.jpg');">
js
function imgChange(im){
document.getElementById('bg').src=(im);
}
You want a crossfade. Basically you need to position both images on top of each other, and set one's opacity to 0 so that it will be hidden:
<div id="container">
<img class="hidden image1" src="http://www.istockphoto.com/file_thumbview_approve/4629609/2/istockphoto_4629609-green-field.jpg">
<img class="image2" src="http://www.istockphoto.com/file_thumbview_approve/9958532/2/istockphoto_9958532-sun-and-clouds.jpg" />
</div>
CSS:
.hidden{
opacity:0;
}
img{
position:absolute;
opacity:1;
transition:opacity 0.5s linear;
}
With a transition set for opacity on the images, all we need to do is trigger it with this script:
$(function(){
debugger;
$(document).on('mouseenter', '#hoverMe', function(){
$('img').toggleClass('hidden');
});
});
http://jsfiddle.net/Ne5zw/12/
Here is a pure css solution using css transition. You can use a div as the container and set the background-image on hover.
.image-container {
background: url(http://placeholder.pics/svg/300x300/DEDEDE/555555/Old%20Image) center center no-repeat;
background-size: contain;
width: 150px;
height: 150px;
-webkit-transition: all .3s ease-in-out;
-moz-transition: all .3s ease-in-out;
transition: all .3s ease-in-out;
}
.image-container:hover {
background-image: url("http://placeholder.pics/svg/300x300/DEDEDE/555555/New%20Image");
}
<div class="image-container"></div>
Just in case someone is curious how to actually create a transition-like effect when you are actually changing the source attribute of an image, this was the solution I came up with.
Javascript:
var bool = false;
setInterval(() => {
bool = !bool;
let imgSrc = bool ? 'hero-bg2.jpg' : 'hero-bg.jpg'; // Toggle image
$('.parallax-slider').addClass('transitioning-src'); // Add class to begin transition
setTimeout(() => {
$('.parallax-slider').attr('src', `https://website.com/images/${imgSrc}`).removeClass('transitioning-src');
}, 400); // Ensure timeout matches transition time, remove transition class
}, 6000);
CSS:
.parallax-slider {
transition: opacity 0.4s ease-in;
-webkit-transition: opacity 0.4s ease-in;
-moz-transition: opacity 0.4s ease-in;
-ms-transition: opacity 0.4s ease-in;
-o-transition: opacity 0.4s ease-in;
opacity: 1;
}
.transitioning-src {
transition: opacity 0.4s ease-out;
-webkit-transition: opacity 0.4s ease-out;
-moz-transition: opacity 0.4s ease-out;
-ms-transition: opacity 0.4s ease-out;
-o-transition: opacity 0.4s ease-out;
opacity: 0;
}
This will give the illusion of 'fading to black and back' between images - even if you're using something like parallax.js where you have a data-attribute driven component that renders out into a dynamic image. Hope it helps someone.
Fixed Mister Epic solution's images in this jsfiddle.
HTML
<div id="container">
<img class="hidden image1" src="http://placeholder.pics/svg/300x300/DEDEDE/555555/Old%20Image">
<img class="image2" src="http://placeholder.pics/svg/300x300/DEDEDE/555555/New%20Image" />
</div>
<div id="hoverMe">hover me</div>
CSS
div#hoverMe {
background-color:yellow;
width:50px;
height:50px;
position:fixed;
top:300px;
}
div#container{
position:relative;
height:200px;
}
.hidden{
opacity:0;
}
img{
position:absolute;
opacity:1;
transition:opacity 0.5s linear;
}
JS
$(function(){
$(document).on('mouseenter', '#hoverMe', function(){
$('img').toggleClass('hidden');
});
});
I'm animating the images so that when hovered over the opacity goes up to 1, that part is working perfectly fine however when images are hovered over in chrome the 2nd column flickers a tiny bit to the side. I've tested it in IE and Firefox aswell and have no issues.
Check it for yourself here: http://abmenzel.com/work/
HTML:
<body class="blue4">
<div class="content">
<div class="work-item blue4">
<img src="img/Template-2-Intro.png"/>
</div>
</div>
</body>
CSS:
.work-item{
width:25%;
opacity:0.8;
overflow:hidden;
display:block;
float:left;
}
img{
width:100%
}
.work-item:hover{
opacity:1;
-webkit-transition: all 0.2s ease-in-out 0s;
-moz-transition: all 0.2s ease-in-out 0s;
-o-transition: all 0.2s ease-in-out 0s;
-ms-transition: all 0.2s ease-in-out 0s;
transition: all 0.2s ease-in-out 0s;
}
I'm also using a script to set the height equal to the dynamic width, which might have something to do with it but I am unsure..
SCRIPT:
$(function() {
var div = $('.work-item');
var width = div.width();
div.css('height', width-5);
});
First of all, put your transition properties in normal element, not on :hover state.
Then, if you need only transition on opacity, use :
opacity 0.2s ease-in-out 0s
That flicker is a known bug in Webkit browsers, it happens when you animate opacity on fluid elements (here 25%).
Here's a workaround:
-webkit-backface-visibility: hidden;
-webkit-transform: translateX(0);
I know it sounds like a hack, but it works...
I use translate3D instead of translateX:
img {-webkit-transform: translate3D(0,0,0);}
