<h3>Advanced Visual Comparison Configuration</h3>
<p>There are additional customizations that can be done by modifying the <b>tests</b> parameter in the comparison URL directly.</p>
<p>URL structure: ...compare.php?tests=<Test 1 ID>,<Test 2 ID>...</p>
<p>The tests are displayed in the order listed and can be customized with options:</p>
<table>
<tr><td>Custom label</td><td>-l:<label></td><td>110606_MJ_RZEY-l:Original</td></tr>
<tr><td>Specific run</td><td>-r:<run></td><td>110606_MJ_RZEY-r:3</td></tr>
<tr><td>Repeat view</td><td>-c:1</td><td>110606_MJ_RZEY-c:1</td></tr>
<tr><td>Specific End Time</td><td>-e:<seconds></td><td>110606_MJ_RZEY-e:1.1</td></tr>
</table>
<br>
<p>You can also customize the background and text color by passing HTML color values to <b>bg</b> and <b>text</b> query parameters.</p>
<p>Examples:</p>
<ul>
<li><b>Customizing labels:</b>
http://www.webpagetest.org/video/compare.php?tests=110606_MJ_RZEY-l:Original,110606_AE_RZN5-l:No+JS</li>
