Improve Accessibility of the Navigation Menu Button

[austinseraphin]

• This is a question about using the theme.
• This is a feature request.
• I have updated all gems with bundle update.
• I have tested locally with bundle exec jekyll build.
• I believe this to be a bug with the theme --- not Jekyll, GitHub Pages or one of the bundled plugins.

While looking at the demo, I noticed that the navigation menu has an unlabelled button. It appears to bring up more options. Labeling the button will depend on its implementation.
