Fixing meta-data, title line height, and capitalize for header

Hi,

I’ve been trying to fix the metadata for ages as the line height was off (too big) but now I’ve been playing around with custom CSS and have messed everything up.

There are three things

1) I’d like the title capitalized (as in, first letter of each word, not the whole thing). Somehow it’s now the whole thing

2) for the metadata (author name, date, category), i’d like a reasonable line height. It’s currently too squashed (this only really matters for mobile as it’ll never stretch across two lines on desktop)

3) I’d like a larger line height for the title. It’s currently a bit squashed (again, on mobile)

vs: what it looked like before (capitalised, which I’d like back) https://i.ibb.co/zG9t9cn/Screen-Shot-2019-12-29-at-11-57-22.png

Thanks so much
