Docs layout lacks 'skip to content' link
Issue Description
When our docs are read by a screenreader, the user must sit (or tab) through the left navigation sidebar before reaching the content of the page. The UX is painful, verging on terrible.
Our application has this line:
<a class="gl-sr-only gl-accessibility" href="#content-body">Skip to content</a>
followed by
<main class="content" id="content-body">
I should check to see if we could implement something similar.
