webkit translateX animation is rolling back to initial position

Question

I am trying to do a images gallery for mobile webkit,

The only way it is actually fast enough is using the hardware accelerated translateX .

My problem is that

Answer 1

Do not use webkit animation for this as it comes back to the default values once played. Instead define

.slideGalleft{
    -webkit-transition: -webkit-transform 1s linear;
    -webkit-transform: translateX(0%);
}

and using Javascript, either set -webkit-transform: translateX(100%); or add a CSS class to your element which set the final transform value and webkit will animate it properly

Answer 2

Guillaume's answer is great. However, if you are looking for hardware acceleration, you must let the webkit engine know you want 3D rendering (what makes hardware acceleration active).

According to http://www.html5rocks.com/tutorials/speed/html5/#toc-hardware-accell, this is done by adding translateZ(0) to your rule, like so:

.slideGalleft{
    -webkit-transition: -webkit-transform 1s linear;
    -webkit-transform: translateX(0%) translateZ(0);
}

Follow Guillaume's advice beyond that.

Answer 3

Use:

-webkit-animation-fill-mode: none/backwards/forwards/both;

This allows you to define at what end of your animation the element remains when the animation is finished.

Answer 4

I was able to make it work by adding a "display:none" style on the finish of the animation. Use the following CSS:

.paused {
    -webkit-animation-play-state: paused;
}

.hiddendiv {
    display:none;
}

Then in your jQuery code:

$('div.sideimage').click(
    function () {
        $(this).removeClass("paused").delay(2000).queue(
            function(next) {     
                $(this).addClass("hiddendiv");     
                next();
            }
        ); 
    }
);

Should work!
