The idea is amazing. But this is how it currently looks on my screen. It doesn't quite work. I've seen a similar project called sassline, where the aim is the same - vertical rhythm. I think he has a different technique which is more in line with how browsers handle line-height.

Time to look back at that cap-height value. The cap-height should be thought of as the equivalent of x-height but for capital letters. Using this height we can accurately set text to a baseline grid on the web. Due to the way CSS renders the space around text, we need to shift the text down by a value of font-size / 2 * (line-height — cap-height). If we want the text below it to sit directly on the next baseline, we need to have a negative margin-bottom of the same value. To get 1 baseline worth of space between them we need to get 1rem minus this value (and so on).

I haven't gotten round to looking at how you guys handle line-height. But if you think this is something relevant I'd be happy to implement the change.
