Which Doctype do you use?
I've had this question on my mind for quite a while now.
I see most email devs using the XHTML Transitional Doctype, with the reasoning of "it has the fewest quirks" or "it's more consistent"
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
I've been using the HTML5 standard Doctype for over a year now and I've personally never noticed any major quirks:
What Doctype do you use and why?
(Some examples of quirks would be great)
