CSS image transition in Mozilla doesn't work [duplicate] - html

Question

I'm trying to make a "fade-in fade-out" effect using the CSS transition. But I can't get this to work with the background image...
The CSS:
.title a {
display: block;
width: 340px;
height: 338px;
color: black;
background: transparent;
/* TRANSITION */
-webkit-transition: background 1s;
-moz-transition: background 1s;
-o-transition: background 1s;
transition: background 1s;
}
.title a:hover {
background: transparent;
background: url(https://lh3.googleusercontent.com/-p1nr1fkWKUo/T0zUp5CLO3I/AAAAAAAAAWg/jDiQ0cUBuKA/s800/red-pattern.png) repeat;
/* TRANSITION */
-webkit-transition: background 1s;
-moz-transition: background 1s;
-o-transition: background 1s;
transition: background 1s;
}​

Answer 1

You can transition background-image. Use the CSS below on the img element:
-webkit-transition: background-image 0.2s ease-in-out;
transition: background-image 0.2s ease-in-out;
This is supported natively by Chrome, Opera and Safari. Firefox hasn't implemented it yet (bugzil.la). Not sure about IE.

Answer 2

The solution (that I found by myself) is a ninja trick, I can offer you two ways:
first you need to make a "container" for the <img>, it will contain normal and hover states at the same time:
<div class="images-container">
<img src="http://lorempixel.com/400/200/animals/9/">
<img src="http://lorempixel.com/400/200/animals/10/">
</div>
with CSS3 selectors http://jsfiddle.net/eD2zL/1/ (if you use this one, "normal" state will be first child your container, or change the nth-child() order)
CSS2 solution http://jsfiddle.net/eD2zL/2/ (differences between are just a few selectors)
Basically, you need to hide "normal" state and show their "hover" when you hover it
and that's it, I hope somebody find it useful.

Answer 3

Unfortunately you can't use transition on background-image, see the w3c list of animatable properties.
You may want to do some tricks with background-position.

Answer 4

I've figured out a solution that worked for me...
If you have a list item (or div) containing only the link, and let's say this is for social links on your page to facebook, twitter, ect. and you're using a sprite image you can do this:
<li id="facebook"></li>
Make the "li"s background your button image
#facebook {
width:30px;
height:30px;
background:url(images/social) no-repeat 0px 0px;
}
Then make the link's background image the hover state of the button. Also add the opacity attribute to this and set it to 0.
#facebook a {
display:inline-block;
background:url(images/social) no-repeat 0px -30px;
opacity:0;
}
Now all you need is "opacity" under "a:hover" and set this to 1.
#facebook a:hover {
opacity:1;
}
Add the opacity transition attributes for each browser to "a" and "a:hover" so the the final css will look something like this:
#facebook {
width:30px;
height:30px;
background:url(images/social) no-repeat 0px 0px;
}
#facebook a {
display:inline-block;
background:url(images/social) no-repeat 0px -30px;
opacity:0;
-webkit-transition: opacity 200ms linear;
-moz-transition: opacity 200ms linear;
-o-transition: opacity 200ms linear;
-ms-transition: opacity 200ms linear;
transition: opacity 200ms linear;
}
#facebook a:hover {
opacity:1;
-webkit-transition: opacity 200ms linear;
-moz-transition: opacity 200ms linear;
-o-transition: opacity 200ms linear;
-ms-transition: opacity 200ms linear;
transition: opacity 200ms linear;
}
If I explained it correctly that should let you have a fading background image button, hope it helps at least!

Answer 5

You can use pseudo element to get the effect you want like I did in that Fiddle.
CSS:
.title a {
display: block;
width: 340px;
height: 338px;
color: black;
position: relative;
}
.title a:after {
background: url(https://lh3.googleusercontent.com/-p1nr1fkWKUo/T0zUp5CLO3I/AAAAAAAAAWg/jDiQ0cUBuKA/s800/red-pattern.png) repeat;
content: "";
opacity: 0;
width: inherit;
height: inherit;
position: absolute;
top: 0;
left: 0;
/* TRANSISITION */
transition: opacity 1s ease-in-out;
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
}
.title a:hover:after{
opacity: 1;
}
HTML:
<div class="title">
HYPERLINK
</div>

Answer 6

If you can use jQuery, you can try BgSwitcher plugin to switch the background-image with effects, it's very easy to use.
For example :
$('.bgSwitch').bgswitcher({
images: ["style/img/bg0.jpg","style/img/bg1.jpg","style/img/bg2.jpg"],
effect: "fade",
interval: 10000
});
And add your own effect, see adding an effect types

Answer 7

Try this, will make the background animated worked on web but hybrid mobile app
not working
#-webkit-keyframes breath {
0% { background-size: 110% auto; }
50% { background-size: 140% auto; }
100% { background-size: 110% auto; }
}
body {
-webkit-animation: breath 15s linear infinite;
background-image: url(images/login.png);
background-size: cover;
}

Answer 8

Considering background-images can't be animated,
I created a little SCSS mixin allowing to transition between 2 different background-images using pseudo selectors before and after. They are at different z-index layers. The one that is ahead starts with opacity 0 and becomes visible with hover.
You can use it the same approach for creating animations with linear-gradients too.
scss
#mixin bkg-img-transition( $bkg1, $bkg2, $transTime:0.5s ){
position: relative;
z-index: 100;
&:before, &:after {
background-size: cover;
content: '';
display: block;
height: 100%;
position: absolute;
top: 0; left: 0;
width: 100%;
transition: opacity $transTime;
}
&:before {
z-index: -101;
background-image: url("#{$bkg1}");
}
&:after {
z-index: -100;
opacity: 0;
background-image: url("#{$bkg2}");
}
&:hover {
&:after{
opacity: 1;
}
}
}
Now you can simply use it with
#include bkg-img-transition("https://picsum.photos/300/300/?random","https://picsum.photos/g/300/300");

Answer 9

If animating opacity is not an option, you can also animate background-size.
For example, I used this CSS to set a backgound-image with a delay.
.before {
background-size: 0;
}
.after {
transition: background 0.1s step-end;
background-image: $path-to-image;
background-size: 20px 20px;
}

Answer 10

Salam, this answer works only in Chrome, cause IE and FF support color transition.
There is no need to make your HTML elements opacity:0, cause some times they contain text, and no need to double your elements!.
The question with link to an example in jsfiddle needed a small change, that is to put an empty image in .title a like background:url(link to an empty image); same as you put it in .title a:hover but make it empty image, and the code will work.
.title a {
display: block;
width: 340px;
height: 338px;
color: black;
background: url(https://upload.wikimedia.org/wikipedia/commons/5/59/Empty.png) repeat;
/* TRANSISITION */
transition: background 1s;
-webkit-transition: background 1s;
-moz-transition: background 1s;
-o-transition: background 1s;
}
.title a:hover{ background: transparent;
background: url(https://lh3.googleusercontent.com/-p1nr1fkWKUo/T0zUp5CLO3I/AAAAAAAAAWg/jDiQ0cUBuKA/s800/red-pattern.png) repeat;
/* TRANSISITION */
transition: background 1s;
-webkit-transition: background 1s;
-moz-transition: background 1s;
-o-transition: background 1s;
}

Answer 11

With Chris's inspiring post here:
https://css-tricks.com/different-transitions-for-hover-on-hover-off/
I managed to come up with this:
#banner
{
display:block;
width:100%;
background-repeat:no-repeat;
background-position:center bottom;
background-image:url(../images/image1.jpg);
/* HOVER OFF */
#include transition(background-image 0.5s ease-in-out);
&:hover
{
background-image:url(../images/image2.jpg);
/* HOVER ON */
#include transition(background-image 0.5s ease-in-out);
}
}

This can be achieved with greater cross-browser support than the accepted answer by using pseudo-elements as exemplified by this answer: https://stackoverflow.com/a/19818268/2602816

Answer 13

I was struggling with this for a bit, I first used a stack of images on top of each other and every three seconds, I was trying to animate to the next image in the stack and throwing the current image to the bottom of the stack. At the same time I was using animations as shown above. I couldn't get it to work for the life of me.
You can use this library which allows for **dynamically-resized, slideshow-capable background image ** using jquery-backstretch.
