How to use alternating colors on tag cloud links? (2 posts)

    I have a tag cloud in my sidebar. While some links appear larger and some smaller, many are the same size. This looks awkward. Is there a way to use alternating colors?

    If two tags are next to each other like "zombie" and "cats" it might make readers think I have one tag called "zombie cats." What I want is "zombie" to be green and "cats" to be blue, so the different colors make them easily recognizable as separate tags.

    Thanks for your suggestions!

    One way to do this is to use a widget that can contain PHP and insert this code:

    <?php
       // Style tag cloud links with 'odd' and 'even'
       $tags = wp_tag_cloud( 'format=array' );
       $switch = 0;
       foreach ($tags as $tag) {
          if (preg_match("/class=\'([^\']+)\'/",$tag,$matches) ) {
             $tag_class = (++$switch % 2) ? 'tag_link_odd' : 'tag_link_even';
             $tag = preg_replace("/$matches[1]/","$matches[1] $tag_class",$tag);
          }
          echo $tag . ' ';
       }
    ?>

    Then add CSS styles for 'tag_link_odd' and 'tag_link_even'.
