Pop-up modal
A button that opens a dialog over the page. Uses a hidden checkbox instead of JavaScript, so it survives the security filters that strip scripts out of most LMS and CRM platforms.
- A tip or an aside that would clutter the activity if left on the page
- Terms, eligibility notes, the long version of a short answer
- Anywhere you want detail available without making everyone read it
Worth knowing before you use one: the Escape key will not close it, and focus is not held inside the dialog. Both need JavaScript. For a tip that is fine; for something a student must read, put it on the page instead.
