I find that the labels I create to put content in the central portion of the Moodle home page, seem to be indented. So when I begin with <div class=blockheading header> xxx</div> I get a colored background that extends outside the topic area at the right. If I first put a </ul> before the <div
I achieve proper indentation (but a bullet precedes subsequent labels
Similar labels I create within other courses do appear normal.
