Created new haml (and html) About page. Tried and failed to attach footer to page bottom, so I'm trying again by first creating a box shadow below the header and above the footer. This will hopefully allow the footer to move down to the bottom of the browser window (when I figure out how to do that) without showing the end of the 'main content' div box. But I'm stuck on how to add a drop shadow to the header and footer without overriding the inner shadow on these two elements. I tried to create a new mixin, but it's not working properly yet. I'm asking for help on Lantern and will keep trying.
