Fully Accessible And Flexible React Modal Component

Description:

A fully accessible and flexible React modal built according WAI-ARIA Authoring Practices.

This module provides a “smart” minimally styled component to wrap you “dumb” fully styled component. It provides the following features, while giving you complete control of the content:

• Focus is trapped within the modal: Tab and Shift+Tab will cycle through the modal’s focusable nodes without returning to the main document beneath.
• Escape will close the modal.
• Scrolling is frozen on the main document beneath the modal. (Although, sadly, you can still mess with the scrolling using a touch screen.)
• When the modal closes, focus returns to the element that was focused just before the modal activated.
• The dialog element has an ARIA role of dialog (or alertdialog).
• The dialog element has an ARIA attribute designating its title, either aria-label or aria-labelledby.
• By default, clicking on the modal’s underlay (outside the dialog element) will close the modal (this can be disabled).
• The modal is appended to the end of document.body instead of its taking up its source-order position within the React component tree.
