If I like an element of a site, and I want to implement it into my site, what is the easiest way to do it? Sometimes there is a lot of CSS files, that is hard to follow all of t
In one word:
Firebug.
Use Firebug to inspect the element, then you can see the cascade. Even better, you can copy and paste right out of FB to a CSS file.
If you want to use other browsers, you can also use their pre-installed developers tools (F12 in IE (requires the IE developers toolbar) right click - inspect element in chrome) or you can use Firebug Lite. :)
