moved  style rules from #hero to .content__header and put repeating rules from #hero, #features, and #mission into a single, reuseable .content object.
moved  style rules from #hero to .content__header and put repeating rules from #hero, #features, and #mission into a single, reuseable .content object.
replaced part #hero with .content__header and replaced #hero, #features, and #mission with a single, reuseable .content object. Since there is no JS hooking on this site, it makes more sense to wrap repeated style rules into classes instead.  This just the start of how much could be abstracted, and hopefully it didn't break the original design.
