Commander Life Minder v1 is a life total tracker for the card game Magic: The Gathering. Using a combination of jQuery and CSS3 features like grid autofit, I endeavored to make an accessable, useful, performant life tracker available over the web for devices of any size. By manipulating the DOM with jQuery, users can initialize games of between one and six players featuring customizable starting health totals. Users can then increment and decrement their life totals by one, five, and ten; the application alerts them by means of a color change when their life total reaches zero.
