Why shouldn't I use position:absolute for positioning everything?

Question

This question is asked by one of my students and I want to enlighten him with an example:

\"Why we should not create site layout by Dreamweaver\'s A

Answer 1

OK, so let's say you absolutely position everything. What happens when #mainContent has one paragraph on one page, and two paragraphs on the second page. Where do you place #footer pixel-wise? What happens if the user increases their font size?

Dreamweaver provides the button because absolute positioning is sometimes useful. That doesn't make it always useful.
