RapidWeaver Stacks add-on info:
The Equal Height Stack will allow you to create content to a grid with equal heights. This is great if you wana stick a button or an image to the bottom of the grid and have all buttons or images aligned across your grid.
On smartphones the Equal Height Stack will release the fixed content (dropzone 2). But what if you have two different grids on your page and want different heights? No problem… the Equal Height Stack has you covered!
Note: The Equal Height Stack is a more advanced Stack than the GoGrid Height Stack that comes free with the GoGrid. The Equal Height Stack allows you to define more than one 'Equal Height'.
