. Certain parts of a site may need a particular set of stylesheets in order to render correctly, and certain other parts may need other stylesheets. I want the user to be able to specify css "dependencies" for various parts of the site, and the correct stylesheets are loaded when the dependencies are present. This is already taken care of, and is just a background for the actual question.
So here's the actual question:
I'm just realizing I may as well get the file-contents of the css file, and output them directly in the head element of the html document like so:
<style type="text/css">
    ---The concatenated contents of every css file the current page depends on---
</style>

Instead of a list like this:
<link rel="stylesheet" type="text/css" href="---link to the 1st css dependency---"/>
<link rel="stylesheet" type="text/css" href="---link to the 2nd css dependency---"/>
<link rel="stylesheet" type="text/css" href="---link to the 3rd css dependency---"/>
.
.
.

Is this a good idea? What are the upsides/downsides of each approach? Doesn't the browser need to perform a separate http request for each included file? Is this outweighed by the cost of sending one potentially very large file, containing all the css code?
Thanks for any advice!

A:

Unless specified otherwise, a browser will choose a locally cached css file instead of loading it again from the server. So most of the time only the html file will be transferred. This is one of the reason I myself prefer to call an external css file instead of embedding it as a tag element.
Another good reason is that when you separate the files it's much easier to edit/update.
Plus, external files remove the need to duplicate styles from one file to another.
Bottom line, most of the time a linked css file will be a much better choice.

This is already taken caution of, and is just a background for the actual question.
