Heya people!

I saw these files somewhere:

style.css
stylesplash.css

But I wonder, what are they?

Is it something like ... that decides how your whole site will look like? Eg, if I type in that I want size 2 verdana, that goes to the whole site and not only to one specific page??

Or is it something else?

they are external css pages.
they contain css coding.
on one or more webpages, that person is linking the webpage to one or both or more of those css pages to import those styles into the webpage.

it is an easy way to have a general set of styles that you can change easily in one spot.

and to learn more about it, you can check this (http://lissaexplains.com/css.shtml) out.
