I'm working on a blog in the latest version of wordpress, and for some reason the site looks fine on Windows browsers Firefox and Internet Explorer, but when I test it on a Mac with Safari or Firefox, the header color stands out a lot more, where you can tell exactly where the header is, but with Windows the header looks seamless with the rest of the design.
Any ideas? I know I havent attached a link, unfortunately the company I'm doing the site for is really strict and doesnt want me to display anything about it. I can try putting up some code tho if that helps.
Your help would be GREATLY appreciated! I'm stuck.
