Tutorial 21: CSS Floats, Part II - HTML with Style
In Tutorial 20, I set an exercise for all of you, to find a way to get multiple-column layouts like those we learned about in Tutorial 19. The trick is to remember that floats, at least according to the CSS specification, do not displace block boxes, only inline content. As we mentioned last time, the rest of the block boxes in the document are layed out as if the float didn't exist at all. So, if we create some space where the float is supposed to float to, it should be floating over a blank part of the page. Confused? Let me explain.
Remember this HTML document? Last time we saw it, we used CSS positioning to put the DIV element with an ID of intro on the left and the DIV element with an ID of main on the right, creating two columns.
