CSS Fade Between Background Images on Hover

Is there a way that I can do the following?

I have a transparent png sprite that shows a standard picture on the left, and a picture for the :hover state on the right.

Is there a way that I can have the image fade from the left image into the right image on :hover using only css3 transitions? I've tried the following, but it doesn't work:

li{-webkit-transition:all 0.5s linear; -moz-transition:all 0.5s linear; -o-transition:all 0.5s linear; transition:all 0.5s linear;}
li{background:url(/img/sprites.png) 0 -50px no-repeat;}
li:hover{background:url(/img/sprites.png) 0 -150px no-repeat;}

Now, the above does animate the background, it pans the image across. What I'd like instead of a pan is a fade or dissolve effect.

UPDATE: I ended up having to create two elements and just animate the opacities separately. It'开发者_开发技巧s a tad messy because I have to specify the exact margins of each element, but I guess it'll work. Thanks for everyones help :)

The latest news on this topic:

Chrome 19 and newer supports background-image transitions:

You haven't specified any code to do the actual transition.

Try this out in your hover style:

-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
-ms-transition: opacity 1s ease-in-out; 
transition: opacity 1s ease-in-out;

Take a look at this: http://jsfiddle.net/j5brM/1/

I think this suits all your needs and its a little bit less complicated.

I don’t think you can change the opacity of just background images in CSS, so unless you have two separate elements for the background image (one for each position of the sprite) and change the opacity of both of them on hover, I think you’re stuck.

li{background:url(/img/sprites.png) 0 -50px no-repeat; background:rgba(80, 125, 200, 0.55);}
li:hover{background:url(/img/sprites.png) 0 -150px no-repeat; background:rgba(100, 125, 175, 0);}

should be

li{background:url(/img/sprites.png) 0 -50px no-repeat; background-color:rgba(80, 125, 200, 0.55);}
li:hover{background:url(/img/sprites.png) 0 -150px no-repeat; background-color:rgba(100, 125, 175, 0);}

not sure if that fixes it or not though.

I know this may be a tad late. But I was struggling with the same issue for a long time. Also with transparent sprites many solutions don't seem to work.

What I did is this

HTML

<div class="sprite-one">
  <span class="foo"></span><span class="zen"></span>
</div>

CSS

.sprite-one {
height: 50px
width: 50px
}
.sprite-one span {
width: 50px;
height: 50px;
display: block;
position: absolute;
}
.foo, .zen { 
background-image: url(sprites.png) no-repeat;
-webkit-transition: opacity .6s ease-in-out;
-moz-transition: opacity .6s ease-in-out;
-o-transition: opacity .6s ease-in-out;
transition: opacity .6s ease-in-out;
}
.foo {
background-position: 0 0;
opacity: 1;
}
.zen {
background-position: -50px 0;
opacity: 0;
}
.sprite-one:hover .foo {
opacity: 0;
}
.sprite-one:hover .zen {
opacity: 1;
}

This is a pure css way & has a bit of a lot of coding.. but seems be the only way I achieved the desired effect! Hope people that also stumble onto this can find some help from this!

<li class="image transition"></li>

css:
.image{
background-image: url("some/file/path.png");
background-repeat: no-repeat;
width: XXpx;
height: XXpx;
background-position: center center;
background-size: cover;
}

/* DRY */
.transition{
transition: background 0.6s;
-webkit-transition: background 0.6s;
}

.image:hover{
background-image: url("some/file/path_hoverImage.png");
}

CSS:-

li { background: url(http://oakdale.squaresystem.co.uk/images/solutions.png) no-repeat left center; background-size: 89px; padding: 54px 0 54px 130px; webkit-transition:all 0.5s linear; -moz-transition:all 0.5s linear; -o-transition:all 0.5s linear; transition:all 0.5s linear; }

li:hover { background-size: 50px }
