I just updated to the latest version of WordPress… Wahoo. I believe I was previously using 2.2.something. The plugin update notification is very nice. The canonical URL fix is also calming to my inner SEO self.
I have to get around to updating the food blog, although I should focus on posting before upgrading.

If a design calls for a graphical horizontal rule, often front end developers will stick in an img tag and call it a day. However, an hr tag would be more semantic - and, most rich text editors for content management systems have a button for the horizontal rule.
These styles allow cross-browser image replacement for horizontal rule. In my implementation, the IE rules needed to be embedded, but it may have simply been a style overriding elsewhere in the stylesheet. Try it in a conditional commented stylesheet first.
The modern method uses background-image to replace the hr, which is defined normally by border. IE works some wonky stuff with list-item and you may have to scoot things around to get it to work just so, but it works!

It's such a simple thing but I actually googled this because I couldn't think of it offhand.
if str has zero characters, len(str) will return 0, mimicking behaviour of false. Cool!
