What does * in a CSS mean?

[fuzzybabybunny]

So I've got this in my CSS and I have no idea what it means.

* {
margin:0px;
padding:0px;
}

* is the universal selector so it is setting the margin & padding to 0px for all elements on the page.

As an aside, I have found I get the best results comparing my pages between different browsers by selecting a strict doctype, setting the margins to 0 for all elements that dont have some other margin set, and then validating the HTML and CSS.

It resets ALL padding and margins to zero. UL's, P's, H1, H2, H3, etc.

It can come in handy, but you now need to space those items. Try googling "css reset".

It means none of the asterisks on the page will have a margin or padding.
