Accordions or collapsing regions

Accordions are a common name for collapsing regions of text  within a web page, usually vertically.

HypotenuseThe hypotenuse is the square root of the sum of the squares of the other two sides.

\( h= \sqrt{c1^2 + c2^2} \)

All triangles internal angles add up to 180 degrees.

They are commonly used to save vertical space on a web page, especially to contain information that is not really part of the main text. For example, definitions, asides or even spoiler information, such as a question with the answer hidden. As you can see, you're not limited in what you can put in them; formatted text, images, videos and anything else you can put on a Moodle page.
