What Hacker News says
3 sourcesIt would be nice if the documentation described or at least linked to explanations of why all the things it highlights are bad. It's relatively obvious why deprecated elements are bad, but what's wrong with links to "#" or links without a title? If you have time, don't just reply to my comment with the answer; Fork and Edit the docs on GitHub (https://github.com/redroot/holmes/blob/master/README.markdow...) so everyone can learn.
The Browser Support section wonders if Holmes.css works on IE9. I tried the bookmarklet on this very Hacker News page, and the only colored borders I see are grey, whereas in Firefox 4 I see all three colors of border - so, it seems IE9 only partially supports Holmes.css.
In CSS Markup DetectiveGreat idea. Even better that it's on GitHub (1). That way it can improve quickly and have community discussions on some of the more subjective markup guidelines.
I think this can be especially helpful on local dev servers (turned on when a DEBUG flag is set, for example) while building a fresh site.
