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. http://heydonworks.com/practical_aria_examples/#progressive-collapsibles * 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.
