Modal Utility

This module provides Javascript and Sass to enable creating modal windows. General UI Events are provided by default (see parameters section) in relation to the modals:

• When a user presses the Esc key, the modal will be removed, and the focus returned to where it came from.
• When a user clicks the modal-mask (anywhere outside the modal), the modal will be removed and focus is returned to where it came from.
• When a modal is shown, its given focus.
• When a user tries to Tab out of a modal, focus returns to the modal.

Getting Started

npm install modal-utility

You only need to import these two files into your build:

dist/_modal-utility.scss

};
