 ### Limit height
 
-Code content uses `auto` height by default but you can opt to set a `maxHeight` value to save space. If the content height exceeds the set max height, vertical scrolling is enabled to scroll vertically to view the overflowing content. A toggle button is rendered as well, which can be used to expand the height and show the Code Block content in its entirety.

 ## Height toggle button
 
-When displaying longer code snippets, it can be helpful to let users expand and collapse the content. Setting a `maxHeight` on the Code Block limits how much is shown by default. If the content exceeds this height, a **Show more code** button automatically appears at the bottom of the block, allowing users to expand it. Clicking the button again collapses the block back to its original height.

Interacting with the button again collapses the block back to its original height.
 
 In Figma, this is enabled by setting `hasToggleHeightButton` to true. The button is placed inside a footer element that only appears when the content overflows, keeping the layout clean when the toggle isn’t needed.
