Sizing and Overflow
Understand how to manipulate element size with Bootstrap 5 width and height utility classes, and control content overflow using different overflow classes. Learn practical ways to manage layout spacing and visibility to create responsive and well-structured web designs.
We have three ways to manipulate the size of an element—by width, by height, or by a combination of both of them. Bootstrap provides us with some built-in classes so we can alter sizes with ease.
Width
The width of an element can be altered using the w class. The width class consists of four types:
.w-25: The element is constrained to use only 25% of its parent width..w-50: The element is constrained to use only 50% of its parent width..w-75: The element is constrained to use only 75% of its parent width.
