Safari Icon   A web page doesn't appear to be using my style sheet

Safari uses the Cascading Style Sheet you specify in addition to any style sheets specified by the page. A style sheet specified by the page may override your style sheet.

If you believe your style sheet should be used by the page, check to be sure you have specified the correct style sheet.

To check that you have specified the correct style sheet, choose Preferences from the Safari menu, then click Appearance.
