CSS files are usually cached so changes won't be seen immediatly by some clients. You often need to do Ctrl+F5 when you change the CSS.

If only a few styles change, then I think you should write those directly in the ASPX page as I would do for small script function that need to chnage dynamically. However, I won't recommand that if you have a lot of styles to generated.
On the other hand, using jquery to adjust styles might make more senses in some scenarios.

You might want to look at Less[^]

Look at the following articles to get started:

http://blogs.msdn.com/b/cdndevs/archive/2014/04/29/refactoring-your-css-with-less-in-visual-studio-web-essentials.aspx[^]

If Less is not an option, look at the crude way of doing it in code behind:
