The most advanced yet simple to use, responsive column layout stack for the Stacks plugin.
The entire concept of this layout system revolves around the magic number 12. There are 12 imaginary columns across the stack regardless of the screen size. You decide how many of those 12 imaginary columns each of your columns in the stack will occupy at the different screen sizes on offer. You can also specify 0 for any column which will hide that column completely.
