Maybe it's time overthrow the W3C and invent HTML6 already, and provide for some proper modern UI widgets instead of needing piles and piles of JavaScript UI-library-of-the-month that create widgets by hacking together a clutter-fest of div hell.
Stuff like <hamburger>, <tabset swipeable="true">, <img pinchzoomable="true" onclick="window.lightbox(this)" lowsrc="..." highsrc="..." ultrahighsrc="...">, <ul pulltorefresh="true" onrefresh="foo()"> should be part of it already, <button> should have more sane margins, font, contrast, and border radius choices by default, <hr> should be low contrast by default as the article says, and the default background and text colors should be #f2f2f2/#222222, and not #ffffff/#000000. Visual centering should be implemented in CSS with a neural net. Let's get standards with the beat.
