Added two things. First using SASS for faster and clearner CSS, Bourbon for access to mixins, and created a psd for the gallery. Decided to place the buttons above the image, since the design will be responsive, to easy access to them
started with HTML only to make sure the barebones are ready
finished statit css, decided to go with max-width from image fexibility with responsive design, would've used Media Queries if i had more elements. Using icon fonts for the arrows just to show the power and potential
added jquery file that loads the json file as well as create the click handlers inside of it. Had a hard time getting the json file to work on local (first time importing a json file in a local computer) Works fine in a localhost environment and in Firefox/safari. Inserted json elements into 3 arrays and iterated them on click events (I would've clean this up better with more time)
