Audit for accessibility.

[pwhisenhunt]

Once the new redesign in #158 is out we should audit the current website for accessibility.

We can probably use https://github.com/dequelabs/axe-core and we can probably add accessibility testing for the React components like in https://gist.github.com/marcysutton/835c2fd90fadb631414b39523d5bda61. Additionally, we should go over the website with a screen reader to verify its read correctly.

Interested in learning more about this!

I just opened up #177 which should be a good starting point for addressing this issue.

Oh and besides #177 we can probably look at adding automated accessibility tests for components with https://github.com/dequelabs/axe-core like in https://gist.github.com/marcysutton/835c2fd90fadb631414b39523d5bda61. Additionally, we should go over the website with a screen reader to verify its read correctly.
