Below is how the bad page was made - I've corrected this version by including all the formatting info in a stylesheet - it looks exactly the same!
I've taken the Page Features page, after making the corrections for its bad features, and now I've added some formatting to the page. In particular:
I think that this is clearer to read, and more attractive.
This accessible version of the page is an exact copy of the better page-features.htm page (plus some text) and with a link to an external stylesheet in which all the formatting is specified.
Also, when you're using abbreviations, use the "abbr" attribute: <th abbr="Monday">Monday</th>.
And if you're using acronyms, use the acronym tag to allow screen readers to read the full version, e.g. <acronym title="Three Letter Acronym">TLA</acronym>.
