Most Efficient Use Of Css

[owosso]

I want to have a general css file. Then I also want horizontal menu specifications and vertical menu specifications.What is more efficient and faster loading: to have one CSS file that is long and contains all of the above code? Or three smaller files and link to all of them?

For most cases, defining them in one file would be more efficient, as the browser only has to make one HTTP request.If a certain piece is used sparingly (say, only in one section from a total of much more sections), it's better to separate that piece in its own file to improve downloading speed at the rest of the site. If it's used almost everywhere (say, in all but one section), it's better to load it all at once.
