Can I move an animated line from right to left?
<p>I'm animating line with css3 from width:0 to width:100%. At the moment is moving from left to right, but I want to make it to start from right to left. Is this posible at all with keyframes?</p>

<p>here is my code </p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code> .content {
   width: 400px;
   height: 200px;
   color: white;
   cursor: pointer;
   text-transform: uppercase;
   padding-bottom: 20px;
   position: relative;
   background: #333;
 }
 .content .line {
   height: 2px;
   background: white;
   position: absolute;
   top: 10px;
   -webkit-animation: dude .75s 1 forwards;
   -moz-animation: dude .75s 1 forwards;
   -o-animation: dude .75s 1 forwards;
   animation: dude .75s 1 forwards;
 }
 @-webkit-keyframes dude {
   0% {
     width: 0;
   }
   100% {
     width: 100%;
   }
 }
 @-moz-keyframes dude {
   0% {
     width: 0;
   }
   100% {
     width: 100%;
   }
 }
 @-o-keyframes dude {
   0% {
     width: 0;
   }
   100% {
     width: 100%;
   }
 }
 @keyframes dude {
   0% {
     width: 0;
   }
   100% {
     width: 100%;
   }
 }</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="content"&gt;
  &lt;div class="line"&gt;&lt;/div&gt;
&lt;/div&gt;</code></pre>
</div>
</div>
