By mhayes:

That line is actually commented out so you can add support for arbitrary height block-grids in everything BUT IE7/8, since they don't support nth-child. So in this case we wouldn't want to move these lines to `ie.css` since IE won't do anything. If you need to change these lines I would suggest creating an overrides stylesheet in your Rails project such as:

`app/assets/stylesheets/foundation_overrides.css`

And then place all overriding styles in this stylesheet. It's an approach that several other gems (such as Formtastic) take to overriding styles provided by a gem. Hope this helps you out!
