Sorin Davidoi 61fad2786b Improve accessibility (#535)
* fix(theme/index): Use nav element for Table of Content

* fix(renderer/html_handlebars/helpers/toc): Use ol instead of ul

Chapters and sections are ordered, so we should use the appropriate HTML tag.

* fix(renderer/html_handlebars/helpers/toc): Hide section number from screen readers

Screen readers have this functionality build-in, no need to present this. Ideally, this should not even be in the DOM tree, since the numbers can be shown by using CSS.

* fix(theme/index): Remove tabIndex="-1" from .page

Divs are not focusable by default

* fix(theme): Make sidebar accessible

Using aria-hidden (together with tabIndex) takes the links out of the tab order.

* fix(theme/index): Wrap content inside main tag

The main tag helps users skip additional content on the page.

* fix(theme/book): Don't focus .page on page load

The main content is identified by the main tag, not by auto-focusing it on page load.

* fix(theme/index): Make page controls accessible

* fix: Make theme selector accessible

- Use ul and li (since it is a list)
- Add aria-expanded and aria-haspopup to the toggle button
- Use button instead of div (buttons are accessible by default)
- Handle Esc key (close popup)
- Adjust CSS to keep same visual style

* fix(theme/stylus/sidebar): Make link clickable area wider

Links now expand to fill the entire row.

* fix(theme): Wrap header buttons and improve animation performance

Previously, the header had a fixed height, which meant that sometimes the print button was not visible. Animating the left property is expensive, which lead to laggy animations - transform is much cheaper and has the same effect.

* fix(theme/stylus/theme-popup): Theme button inherits color

Bug introduced while making the popup accessible

* fix(theme/book): Handle edge case when toggling sidebar

Bug introduced when switching from animating left to using transform.
