Space between lines in CSS

Hey, I got a little question...

It's about the space between each line of text in a normal page... how can I change it in CSS (or in html if it's not possible otherwise)

I think I knew it before, but forgot what it is...

Thanks for any help!!

p {
line-height: 1.6em;
}

Thank you deker!

Do you know what represent em though? It's probably a stupid question, but I'm kinda tired right now and can't figure it out :/

em is the width of the letter M in the font that is being used. so basically it is 1.6 times the width of that letter. you could also just do like 18px or something, but it is less flexible.

so why do people use ems as opposed to pixels?

Because that way if someone changes the font size in their browser, everything scales with it. You can also set the width of pages and boxes and stuff with ems, so that the whole web site will scale larger or smaller, depending on their preferred font size.

interesting.
