That looks really nice! Was that a theme you downloaded or did you do all those changes yourself? Now, as much as I like the look, I’m not entirely sure about the big stip of pink creating all that space to the right of the menus. It makes it a tad awkward looking, like that strip wants to be the menu, but instead it’s just sitting there beside it, or something.
Anyway, the footer is also askew in Safari (Mac browser). I’m totally new to this as well, so I can’t tell you how to fix that, but I’m sure someone here can.
Firefox is well worth downloading. It’s a far superior browser to IE and I think you’ll find that most people in to their blogs and customizing them are often using a browser other than IE.
Anyway, nice work and good luck!
