These are fairly straight-forward HTML attribute completions for Sublime Text, including most HTML5 attributes. It includes completion of many standard values. For example, typing the letter 'c' in the type="" attribute will complete "checkbox". If you Backspace and enter the letter 't' it will be replaced with "text". "text/css" and "text/javascript" for the type- attribute are inserted by typing 'j' or 'cs' within the quotes. There are two versions for some boolean attributes. For example: CHECKED, or checked="checked" Depending on your settings you may need to press Ctrl-Space to display the completions within an opening HTML-tag. I just type 1 or 2 letters and press the Tab key! This uses the fuzzy-search feature of ST, and ST will also 'learn' about your preferences. With a little practice you can fill-in attributes extremely quickly. Note: The Emmet (formerly ZenCoding) package uses a different approach, so it may not sit comfortably with HTMLAttributes.
