In CSS, an overflow occurs when the content of an element exceeds the size of its container. There are several properties that can be used to control the overflow behavior:
overflow: visible: This is the default value and it allows the content to overflow from the container, overlapping other elements if necessary.
overflow: hidden: This property hides any overflowing content and does not display it. This can be useful when you want to clip the content and not display any of the overflowed content.
overflow: scroll: This property adds a scrollbar to the container, allowing users to scroll and view the overflowing content.
overflow: auto: This property automatically displays a scrollbar only when the content exceeds the size of the container. Otherwise, it behaves like overflow: visible.
overflow-x and overflow-y: These properties allow you to control the overflow behavior specifically for the horizontal and vertical axis respectively. For example, overflow-x: auto; overflow-y: hidden; will display a horizontal scrollbar but hide the vertical overflow.
It’s important to note that for overflow: hidden, the overflowing content will be hidden and not accessible, so it’s important to consider the impact on usability and accessibility before using this property.
