I had no idea this can be done. Very nicely written article by Jonathan Snook on using css attributes to rotate text on a webpage.
Hell lot of browser quirks, almost zero consistency across different browsers and different operating systems, but I am not complaining. Most of the newer attributes like opacity started off as browser-specific.
Hope to find this more consistent a year later. After all, we shouldn’t be forced to use images just to display text in a different orientation, right?
