You are really making me want to do this. I liked the colored groups- that's actually useful information, disregarding its superficial similarity to the "real" periodic table of elements. It would be interesting to see a table that does a good job of grouping along other attributes like you've described here. It pretty well falls along the lines of what I once wrote about- that HTML should be split into multiple, mutually exclusive sub-languages- with guarded sections of code that does not permit tags from any other groups to be interpreted as actual tags, as enforced by the browser. If browsers had this ability: to whitelist certain tags, imagine how many XSS attacks we could avoid, by having a special container in which script and style tags (and any other tags or attributes that cause the evaluation of code) strictly do not and cannot work. OH well.
