Bootstrap Overflow

When the contents are larger than their element then there is a chance of overflow. The overflow on any element does not make your website look good. Bootstrap adjusts this overflow using its default value and classes.

The notation used for overflow is .overflow-value where values are

  • .overflow-auto - It automatically adjusts the overflow with a set height and weight. The contents will vertically scroll.
  • .overflow-hidden - It hides the contents which are overflown.
  • .overflow-show - It shows the overflown contents. The contents can expand beyond the given element block.
  • .overflow-scroll - It will scroll down the contents from the element with set height and width.

Example: Overflow in Text

In the below example, we have shown how the overflow can be adjusted with the help of overflow classes. The container has predefined dimensions and the contents get adjusted according to the function of the classes.
