when a website loads, many sites have a separate css file to load styles on their site. You can view it directly if you know where the file is OR you can download web developer tools for firefox. Internet Explorer has one too. I prefer the firefox one and there are options for things like showing css, disabling css, disabling javascript, etc. It helps too with debugging div tags and table layouts. Anyway, that is how you do it. It's just like viewing the source (html) of a webpage. Noone can change it, but they can see your code
