Actually, you can view a linked stylesheet. Just follow the path by viewing the HTML document, and then type it in the location bar. Your computer will either download it (in like a second, no long download) or it will display it in Notepad, etc.
To change the color of a text field (textarea too), in the CSS script, put:
background:background color or image path;
font-family:Times New Roman;
That should work, and if it doesn't, than you probably aren't using a CSS browser.
