A link to your site would help.
The tag cloud links themselves are all inside <div class="st-tag-cloud"> and are simply separated by a single space:
<div class="st-tag-cloud">
<a id="tag-link-10" class="st-tags t1" style="font-size: 8pt; color: rgb(87, 150, 184);" rel="tag" title="12 topics" href="http://cohmissionreview.com/tag/5thcolumn/">5th Column</a>
<a id="tag-link-28" class="st-tags t2" style="font-size: 9.11pt; color: rgb(105, 161, 191);" rel="tag" title="18 topics" href="http://cohmissionreview.com/tag/arachnos/">Arachnos</a>
[...]
</div>
The font size is being applied inline as per the standard wp_tag_cloud() template tag but text color is also be applied in rgb format – which isn’t part of wp_tag_cloud. So either the cloud is being generated by a plugin or via a customised function in the theme’s functions.php file. If you’re not using a tag cloud plugin, have a look at sidebar.php and see what comes immediately after wp_get_archives. It might give you a clue as to what function is generating the cloud.
I can’t see anything in the current CSS for the cloud, so I’d suggest that you add your own CSS to the bottom of style-sidebar.css using .st-tag-cloud and .st-tag-cloud a.
Hope that helps.
That helped immensely. Sometimes, all it takes is a little push, huh? 🙂
Thanks very much!
