Do you 'search?q=CSS' ?

A recursive item I search on the web for is Cascading Style Sheet, also known as CSS. I guess most of the information on the subject can easily be found on the net and because of
that I haven’t acquired any reference book yet. But I should, because there’s more to know than it seems.

Take CSS positioning (position:) for example, what does absolute, relative or
static positioning really mean? Or what’s the difference between using em, px ou % as an unit? What’s a container? Div, span, id, class? Well.. you get the point..

On my wishlist about this topic I have the book “The Zen of CSS Design : Visual Enlightenment for the Web (Voices That Matter)” but there’s also one by O’Reilly called “Cascading Style Sheets: The Definitive Guide, 2nd Edition” that seems pretty good.

There’s certainly more than one good reference out there on the Web about CSS but surely not too many in Portuguese, as this Brazilian site called I totally recommend it as I’ve found priceless information there.

Although most of the time ommited, CSS is definitely part of the second phase of architecture and application development for the World Wide Web now beginning to be known as the Web 2.0 phenomena and it certainly plays an important role, we all agree on that.
