问题
I am currently working on sidebar navigation for a mobile site and I am trying to include the below animation for the main menu button.
This works well on different browsers except for mobile devices running iOS - Safari and Android - Android Browser. What am I missing? Thanks.

Hi I tried your fiddle and it worked on my mobile, which is iphone5s. But anyway, as far as I've known, when you want to use keyframes-translate for an element. The element has to be displayed block, or it has to be wrapped by a div, which default is displayed block too.
a {
background:orange;
}
div {
-webkit-animation: move 5s infinite;
}
@-webkit-keyframes move {
0% { -webkit-transform: translate(20px); }
100% { -webkit-transform: translate(500px); }
}<div class="wrapper"><a href="#">Test</a></div>I'm thinking maybe translate doesn't support some elements completely. For instance, when you want to translate a tag element, you have to set the element display: block.
However, when you want to apply translate on a div element, if you set the css on the div element display:inline-block, the translate will still work on that div.
So maybe try to set the elements that you'd like to move display:block.
