Emmet snippets - in the interest of standardizing markup between projects a little more. Install Emmet via the Sublime Text package manager, then paste any of these snippets into an html document and hit tab (or tab-enter, or whatever you've set as your Emmet trigger key). Pieces added in no particular order.
