Thanks for responding. I'm not really a web dev, so I haven't thought about it much.

The tab layout and <div> examples were definitely not things I was thinking about. I guess that's a good incentive to use tags like <section> and <article> instead of divs with CSS classes.

I'm actually a bit color blind myself, so I appreciate sites being high contrast and not relying on color alone for indicators. A surprising number of sites completely break when trying to zoom in and make text bigger too, which is often due to bad floating layouts. Especially if it's resized with JS...
