How to hide long text in standard blocks?

If you are using a standard block from the Block Library that contains text, you can hide part of the text and show it when a visitor clicks the expand button.

To hide text, select it in the editor. In the pop-up context menu, click the three-dot icon and select Collapse text.

In the new window, you can enter the labels for the expand and collapse buttons, as well as customize their color and style.

After making the changes, save the settings and open Preview mode to check how the hidden text looks. Then publish the page for the changes to appear on your website.
