Sizing and Overflow

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.

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.
