DOCTYPE grid

NOTE: These results should NOT be taken as authoritative. DOCTYPE switching is a tricky thing to test, requiring more work than I've been able to plow into it. Consider the following information a rough guide at best, and subject to change as further testing warrants. Thank you.

Entry	Meaning
Q	Quirks mode
A	Almost-standards mode
