This chapter discusses about the overflow utility of Bootstrap. The overflow utility classes are used to control the behavior of overflowing content within an element.
Bootstrap provides several utility classes related to overflow. By default these classes are not responsive.
Class | Description |
---|---|
.overflow-auto | automatically adds the scrollbar to the element if the content exceeds the dimensions of the element. |
.overflow-hidden | hides the content when it exceeds the dimensions of the element. |
.overflow-scroll | adds the scrollbar to the element regardless of whether the content exceeds the dimensions of the element or not. |
.overflow-visible | allows the content to overflow the dimensions of the element without clipping or scrolling. |
