This industry moves fast — really fast! If you’re not careful, you’ll be left in its dust. So, if you’re feeling a bit overwhelmed with the coming changes/updates in HTML5, use this as a primer of the things you must know.
1. New Doctype
Still using that pesky, impossible-to-memorize XHTML doctype?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
If so, why? Switch to the new HTML5 doctype. You’ll live longer — as Douglas Quaid might say.
In fact, did you know that it truthfully isn’t even really necessary for HTML5? However, it’s used for current, and older browsers that require a specified
doctype. Browsers that do not understand this doctype will simply render the contained markup in standards mode. So, without worry, feel free to throw caution to the wind, and embrace the new HTML5 doctype.
