Hello, my first post on this forum and a novice at web design.

This may be a real basic (stupid) question but I'm confused.

I thought stylesheet.css was typically written in HTML?

I have my page up and running and in the process of tweaking bits. I use mozillla firebug to view and test edit the html source code. I copy the changes into s text document.

I open the sylesheet.css ecpecting to see the same html as the source. The CSS looks nothing like the source code / not in html. Is this normal?

Should I expect css to be a different language to html?

Cheers
