Accordion
In short and in plain language
An accordion is a part of a web page that you can open and close.
It often holds questions. You only see the answer after a click.
You should be able to open it with the keyboard. A screen reader should say if it is open.
Definition
An accordion is a control that collapses content under headings and expands it on request, for example in a section with frequently asked questions. It works well when each section can be opened with the keyboard and screen readers announce whether it is open or closed.
