I haven’t looked into the best way to write web pages that accommodate zooming, but there is a huge variety in how pages perform as you zoom.
Loads of sites don’t do it properly, where you zoom and all the text and images get squashed in the middle of the page, or where the elements disappear off the side of the page. The other horrid thing is when you zoom and then the text is the right size but you end up having to scroll left to right to read the text.
The best sites perform perfectly at every zoom level, with all the content resizing properly so the reading experience is always pleasant.
I’d love to read some tutorials on how to ensure your website performs in this way. In my opinion it’s one of the signs of a really skill-full developer.
I can read smaller text for a bit in a single block, but when it's something like a comment section I need things a lot bigger to be able to skim through comments to spot things I'm interested in.
