I know you copied some code from somewhere else for the preview/hover slide effect, but I would have renamed the classes from `.boxgrid` to something that makes more sense for our situation, like `.template-preview` maybe? It makes it a bit difficult to read this javascript and know what it's doing. The best code is self-documenting, in that it makes complete sense when someone else is reading through it that there doesn't need to be any comments to explain what's going on.
