Mention white-space solution
I really like the idea of using inline-block instead of floats but while developing it's a pain to use HTML comments ect. and the letter/word-spacing hack is pretty awful as well.
I've developed a small script that can help during development - https://github.com/dotnetCarpenter/white-space
I'm using csswizardry-grids together with the script and so far it's been great. If you like the idea, it might be worth noticing in the README - Note the empty HTML comments.
Personally, I would recommend minifying and gzipping the HTML content in production, to leverage the problem, but your mileage could vary.
Looks fantastic after a quick test, thank you!
@lekkerding nice. Let me know if you're having any issues or feature requests.
