It's a great visual explanation, but the page is full of typos and spelling mistakes that can easily be caught by default spellcheckers.

I can issue a pull request with the corrections marked up if you have a git repo somewhere.

Unfortunately, the textual errors are detracting from the great message of the page.

Most of the "Don't" points use extremely unclear wording, too. Example: "DON'T: Avoid text being on top of that clickable stuff as it becomes unclickable..." Uh, don't avoid that? A couple are also "DON'T: <statement of fact>" which is confusing. Given the audience this is aimed at, those DON'Ts are probably doing more harm than good.

and some that a spellchecker may not catch, such as "brake" instead of "break"

Damn typos. Thanks!
