I know, I know, I did it to myself. Please see http://www.racinewebworks.com/blog. Two different posts, two different days, two different sized fonts. What’s going on? I’m about bald over this one. Thanks!
I figured it out, though I’m not pleased with the solution. I’m using Blogger to power the blog and FTP to my little site. The key is to use Blogger’s WYSIWYG to compose posts, and not work directly w/ the HTML. Blogger inserts </ br> instead of a new <p> for breaks, and this seems to help things. BTW, the wonky code is part of Blogger’s template, and I haven’t modified the template enough to safely remove the extra div. Finally, beware nesting em-based font sizes, it’ll get ya every time!
