Shouldn't this project rely on compass-normalize to provide the normalize mixins? Less maintainance burden :)
Thanks for the heads up. Was not aware of this project until now. However, in the past html5-boilerplate used a heavily modified version of normalize.css that had differences specific to h5bp. Not sure if all those differences still exist, but it might be worth looking into.
I think H5BP made their defaults a lot less opinionated. Only difference I can see is H5BP sets background-color and color on <html>, while compass-normalize sets font-family.
Also, compass-normalize supports normalize 1.1.0 and 2.1.0 and uses the Compass browser support variables to switch, so setting $legacy-support-for-ie6|7: false removes all the hacks.
I'm continuing to look at this, but currently compass-normalize is a version or so behind H5BP v5's implementation. This is a good idea still.
This won't be done, as compass-normalize is no longer maintained, and it'd be more trouble to maintain it than just keep the code in this codebase, especially in light of the demise of Compass itself as an actively maintained project.
