I never understood why these webpages can't have like, 4 lines of CSS to make them much more readable. Preserve the older aesthetic I guess?
Maybe because the author's expertise is something other than writing HTML, so he picked up an old book on HTML, marked it up, and that's it. That the browser can render HTML written 20 years ago is quite a virtue. If it only takes 4 lines of CSS to make it more readable, then the page's lack of readability is more an indictment of the browser (which could do this tidying itself) rather than of the author, who should…
I strongly disagree with this. The browser should do nothing it is not explicitly made to do, which is one of the reasons it can still render HTML from 20 years ago. We used to have browsers that tried to do that kind of thing and we're only now extracting ourselves from that mess.
It is 100% on the website author to make their page more readable.
