Section size and ratio

[luoar2005]

Hi,
first of all: thanks for all the good stuff you're doing!

I was wondering how I could make sections preserve their size and height ratios no matter how much content is on them, so that I can position headers etc. on the slide and have them all appear in the same place, independent of the the other content on that slide? (My question is basically the same as this reveal.js one I guess: hakimel/reveal.js#1312).

Would be great if you could help!
