Exactly! My first attempt was just 10 lines of HTML code, but it was a real pain to do the vertical centering on iOS. So I tried a Bootstrap template, saw that even they didn't do the centering on iOS, but was too lazy to change it back.

Modern iOS should support flexbox, which should get you what you want with a few lines of CSS. http://caniuse.com/#feat=flexbox

Or you can throw this in a table and be done with it.

Haven't you heard? Only noobs use tables. Also your design totally won't scale and isn't internet grade :)

iOS does, but it is a bit funky sometimes and has some weird bugs.
