Is it ok to use multiple style sheets? I ask because I have a page I'm playing with that uses a script. The script came with it's own style sheet. Should I incorporate it into the style sheet I'm making for the rest of the page or keep them separate?
You can have as many style sheets as you want. Some people have preferences that they want to keep the layout and the presentation in separate files. You might have to deal with same id's or classes in different files. But yes, you can have several style sheets in one page.
