FireFox prefix extensions

Hi all,

I'm using Firefox 25 on my computer. I'm trying to using the keyframe animations but I can't get them to work.

I've tried adding the -moz prefix to the repeating-linear-gradient, animation-name, and animation duration properties, as well as the @keyframe property but all I get is a screen with a blank box. Please help.

Here's my code:

body {
    background: #303030;
    font: 1.1em sans-serif;
.wrap {
    box-sizing: border-box;
    margin: 70px auto;
    padding: 5px;
    width: 600px;
    border-radius: 10px;
    background: #222;
    box-shadow: inset 0 0 1px rgba(0,0,0,.6), 0 1px 0 rgba(255,255,255,.1);
.prog-bar {
    height: 60px;
    border-radius: 5px;
    background: -moz-repeating-linear-gradient(-45deg, rgba(255,255,255,.1), rgba(255,255,255,0) 12px), -webkit-linear-gradient(#F5A8A8, #F08080);

  -moz-animation-name: slide;
  -moz-animation-duration: 2s;

/*  Keyframes
------------------------------------------ */
@-moz-keyframe slide {
  from {width: 0%;}
  to {width: 100%;}

I fixed it for you. You start with CSS added but end with only the backticks to close. Still close though!

no prob

And I figured it out. I forgot to add the prefix to the other gradient in the background property.

You're on the right track to get your code to show up in the question, but you're just missing the CSS part. (```CSS) <--without the parentheses
