The 960 Tropical Grid was developed by Gregg Ferris and created for web developers who want a grid that supports all browsers - including IE7 and IE8. The 960 Tropical Grid uses a 12 column and a 24 column grid layout and is responsive. The 960 Tropical Grid also has a color picker for selecting colors on the fly and notes pallet for taking notes while your developing your website(like shown on this webpage). We used PHP as the backbone for the 960 grid layout and most of the functions.
