«Label Cloud Widget»

I've added a new widget at the bottom of the page. It's a label cloud; the larger and brighter the link, the more posts there are that have that label.

I saw the widget in use on a random blog I came across, and I really liked it. After a little searching, I found the code and where it came from. I'm using the version that can be found at Widget-based.

For the sake of preservation, I'm going to include the code for the widget here as well. There hasn't been a new post on the Widget-based blog since 2006 (only 8 total posts), and I'd hate for it to be deleted and this version of the code lost.

Installation in two parts, you'll want to Expand Widget Templates for this:

1. CSS code. Goes anywhere between the tags <b:skin> ... </b:skin>, preferably right before the end tag.
   
   

   /* Label Cloud Styles
   ----------------------------------------------- */
     #labelCloud {text-align:center;font-family:arial,sans-serif;}
     #labelCloud  .label-cloud li{display:inline;background-image:none !important;padding:0 5px;margin:0;vertical-align:baseline !important;border:0 !important;}
     #labelCloud ul{list-style-type:none;margin:0 auto;padding:0;}
     #labelCloud a img{border:0;display:inline;margin:0 0 0 3px;padding:0}
     #labelCloud a{text-decoration:none}
     #labelCloud a:hover{text-decoration:underline}
     #labelCloud li a{}
     #labelCloud .label-cloud {}
     #labelCloud .label-count {padding-left:0.2em;font-size:9px;color:#000}
     #labelCloud .label-cloud li:before{content:"" !important}
    



2. Widget. Goes anywhere between <b:section id="'sidebar'"> ... </b:section> (or where ever you want it in your template).
   
   

   <b:widget id='Label1' locked='false' title='Label Cloud' type='Label'>
   <b:includable id='main'>
    <b:if cond='data:title'>
      <h2><data:title/></h2>
    </b:if>
    
    <div class='widget-content'>
    <div id='labelCloud'>    <ul>
      <b:loop values='data:labels' var='label'>
        <li>
          <b:if cond='data:blog.url == data:label.url'>
            <data:label.name/>
          <b:else/>
            <a expr:href='data:label.url'><data:label.name/></a>
          </b:if>
          (<data:label.count/>)
        </li>
      </b:loop>
      </ul></div>
   <script type='text/javascript'>
   // Label Cloud User Variables
   var maxFontSize = 20;
   var maxColor = [168,181,248];
   var minFontSize = 8;
   var minColor = [0,0,0];
   var lcShowCount = false;
   var minPostCount = 0; //integer

This is the first blog post that uses my new code boxes. I'll still use the old style for short code snippets.

EDIT: I've decided to maintain consistency and use this style of code block for all code; even short snippets. Please tell me what you think of it.
