missing '-webkit-padding-after' and '-webkit-padding-before'

[Rykus0]

Noted after applying autoprefixer

Probably also -webkit-margin-after and -webkit-margin-before as well

My guess is that these were ultimately dropped, which is why they're not included. If they won't be included in the library because of that, I totally understand. I just noticed these and wanted to bring them to your attention.
