Any way to practice web page creation offline?

When I was 11, I created a web page for my guild in Neopets, lol. It was well done, and I remember constantly practicing on a blank neopets page that we were given to play with. They had their own tutorial on basic web design, and I kept experimenting.

Well, 8 years later I want to get back into practicing. Is there some way offline that I can play around with HTML? Maybe using notepad and a web browser?

If not, list some ways I can practice HTML, so I can play around with web page creation and see my work.

Thanks!
