When doing a fluid layout with cs6, If I wanted to add another page, Would each page have its own css fluid style sheet.
Would each page have its own css fluid style sheet.
No, you would code just one CSS stylesheet and all pages would be linked to it.
You would probably use the same page and hit File > SaveAs page2.html.
Repeat with other site pages.
However, if you intend to use a different layout on internal pages, you may need more than one CSS file.
