adjusted headers from Jordan's feedback

> On "Career" page, the list headers are smaller than the list items. (They should be larger.)
adjusted mobile social icon spacing

> Social icons are too close together on mobile. Increase space between them. (Either that, or just make it 2 lines.)
fixed strange text alignment

> On the "Home" page, you've used a combination of left-aligned elements and centered elements. This makes the left-aligned elements look a bit foreign. Try to rearrange the text elements so they don't look like they're all by themselves (on larger resolution screens). In some cases, you may be able to eliminate them. (You could probably remove the "And more" link.)
