What is the Overflow setting and how does it work?

The Overflow setting applies to the entire block and controls how elements that extend beyond the block boundaries are displayed.

There are three options: visible, hidden, and auto.

Visible — Elements outside the container remain visible and can overlap neighboring blocks.

Hidden — Elements outside the container are hidden.

Auto — If elements extend beyond the container vertically or horizontally, a scrollbar is added to the block.

For example, you can place a long article inside a block without making the entire page much longer. With overflow set to auto, the content that extends beyond the block can be scrolled within the block.
