I've been working more on improving mobile layout of articles and I have some centering concerns. I have this template that has all content centered in all views I've seen besides mobile (example). The header and the links below are centered using  tags and the text below is centered using tags. The text below is the only text that's centered in mobile yet I know it's not supported in HTML5. How should I go about getting all text in question centered in mobile as well as all larger screen?
