So I have Facebook Share/TweetMeme widget/plugins installed. When used, they look like (the top picture below). The problem is the widgets, when activated, don't really provide space and allow the "comments/tags" to follow up after it. So I am wondering, how can I style it so comments/tags go underneath (like in the bottem picture).
In your styles.css file, on or about line 665, for .postmetadata include a clear:left; inside the curly brackets. There also seems to be a blank <p class="postmetadata"> somewhere in your theme. Typically, this should be included in a DIV and not a P element. But it still works. If you can post the code from that section of your theme, maybe we can straighten this out a little.
What? The stylesheet or the code? The stylesheet is your main theme stylesheet, of course. So I am assuming you are talking about the code, that I cannot tell you. Most probably in a few files called single.php, archive.php, etc. I think this may appear in more than one file.
