If you're interested in CSS layouting, consider learning Flexbox and then CSS Grid first. These are both relatively straightforward with good documentation and relatively few quirks (esp. grid). You don't really need flow layout at all these days. And you can certainly skip floats and table layouts entirely (use them only for their originally intended purpose of floated images within textual content and literal tables).
