When I looked at the html using Blogger, I discovered some strange html that looked like this (substituting square brackets for angled ones, so you can see them here):
[span class="addmd"]This class apparently has something to do with whatever program is displaying the page. Google's word processor knows what it means, but Google's Blogger doesn't.
Why isn't indenting a standard html function?
And why does Blogger indent the title and the first line of every article, and only the first line? That might be a function of the template I'm using, but still.
