Thread:Project:Support desk/Edited Vector Skin - Only my personal Safari renders it

I've been working on editing the Vector skin - only CSS, mind you - and I tried to test it in my Firefox, my Chrome, another computer's Safari and Firefox, and none of them display right, at all. It becomes an unstyled white page, with black text and the like, while mine renders as it's supposed to.

Anyone know why?

Here's the link to my wiki.
