Periodic Table of HTML5 Elements

You've already known the periodic table of elements in chemistry from your early school days.
How about a periodic table for HTML5 elements?

Josh Duck prepared the following HTML5 periodic table showing the 106 elements currently in working HTML5 draft and two proposed elements.

You can view the original HTML5 periodic table from Josh Duck's web site. You can even interact and see descriptions of each element. It is very useful, try it.

HTML5, Still a draft

HTML4 has been standart since 1997 and there is unquestionably  a need for a better standard. HTML5 will be the latest HTML standart but it is still under development.

HTML5 is still a draft but many browsers have already started to adopt it. It is good to see the potentials of HTML5 before it is fully released. However, there are also some criticism over this strategy. Different browsers' adopting different draft versions will make them incompatible with each other and this will cause the same website will not look same in different browsers.
