The modal dialog is missing a close button
Functionality MUST be available using the keyboard, unless the functionality cannot be accomplished in any known way using a keyboard.
Some people cannot use a mouse due to vision or motor disabilities. Content that can be operated with a mouse must also be made operable with a keyboard. When content is operable through a keyboard, it becomes operable by a variety of assistive technologies such as speech input software, sip-and-puff software, on-screen keyboards, scanning software, and alternate keyboards.
Fix this issue by providing a method to dismiss/close the modal dialog, such as a close button or similar that:
- Is keyboard and touch operable and
- Works with assistive technology running and
- Is visually apparent
