Lynne, I tried what you suggested. According to the source, it is "cms_widget_header"
Code:
<div class="cms_widget">
<div class="block">
<!-- Widget Header -->
<div class="cms_widget_header">
<h3>Recent Blog Posts</h3>
</div>
<!-- SEARCH RESULTS DATA -->
<div class="cms_widget_content">
<!-- BEGIN TEMPLATE: vbcms_searchresult_blogentry -->
There is a vbcms_widget_headerfont stylevar, but it doesn't have the feature to change the color...just the size. There is no template with the name cms_widget_header, or anything similar from what I can tell. I see that the "Recent Blog Posts" is coded in with just the h3 tag...does this mean there isn't a template to change the header after all, and that there is only one for the search results displayed under it?
