You're right.. from a fresh 1.36 install with your contrib, the effect was very much minimized. On mine (very much NOT fresh 1.3.6) It was grotesquely obvious there was a difference in the buttons. And I never could understand why. I stripped the css down as much as I could to figure it out, but eventually just gave up.

My reason to use css buttons was different than yours. My goal was to make an elasticly rendered site so that visually-impaired people could increase the font size and still see my site the way it was intended. The graphical buttons make that impossible so I went toward css...

until I realized it wasn't impossible with graphical buttons.. just difficult :)

I'm there though. My site is 99% elastic! You can increase/decrease and zoom in/out to your heart's content (and browser's limits) and my site will stay exactly as it is intended.... formatting doesn't get screwed up because images now grow and shrink along with the text... something many "authorities" on the web say is impossible :)

DOWN WITH PIXELS!!
