 ### Collapsed content styles
 
 You can use this component to hide almost any content. This can be a text content, an additional information (for example, in a table), or even an entire table with a chart.
 
 **Remember about visual hierarchy when designing the accordion**. If you use, the accordion, for example, in a table, then the title inside the accordion shouldn't be equal to or greater than the size of the main titles on the page.
