Reply To: Floats for layout?

Great point you have there. But I have a few more questions to you.

First of all, how do I know when I should use display inline-block, tables, floats or whatever else. How do I know which one is the correct for the current situation?

The second question is… how do you determine whether you have to support IE9 and below or not? Case scenario one: I create your own project, so how do I know if I should support IE9 and below or not?

Case scenario two: I work at a company or as a freelancer. In that case I suppose my client will tell me if I should support it or not?
