Or you can make separate file - filename.css, and in head put this
<link type="text/css" rel="stylesheet" href="url" />
But what is the difference between these two ways?
I use the second one because the html source code is shorter, and you can use the same .css file on many pages.
which browsers don't support css?
The difference between having the CSS included or excluded in the file is that if you exclude it to a file. The users gets faster browsing because their browser caches the .css-file. If it's included in the header, it gets loaded for each pageview on the site. So if you do a CSS/DIV layout, and use as much CSS as HTML code in your documents. You can reduce the loadingtimes to 50% for all pageviews except from the first one.
