This stylesheet uses CSS to replace author defined fonts with user defined fonts.
This CSS file can be used both to replace fonts on all sites and for specific sites through the site specific preferences dialog. By default, it will set all headings to be Arial, if that font is not available on your PC Helvetica will be used or your system's default sans-serif font. For the body text Georgia will be used or Times New Roman if you do not have Georgia. Preformatted and code text will be in Courier New. These settings will override any settings by the site's author. Unfortunately it will only work if text is properly tagged.
Not everyone likes rounded corners, this *very* simple .css file gets rid of them for you.
If you apply this css file through site specific preferences or general preferences it will get rid of CSS made rounded corners. It can't do anything against corners made with images or javascript i'm afraid.
Remove any brightness from webpages - ideal for surfing in the dark. Very pleasing on the eyes.
