About the Unit

Percentage (%): Percentage is a relative unit of measurement that expresses a value as a fraction of 100. It is widely used in CSS to define dimensions of elements in a fluid and adaptable manner. For example, if you define an element's width as 50%, it will occupy half of its parent element's width. Using percentages allows elements to automatically adjust based on their container’s size, which is ideal for creating responsive layouts that work well on different devices, such as smartphones, tablets, and desktops. Percentage is also useful for properties like margin, padding, and height, where you want the element to adjust proportionally to its parent container, rather than setting a fixed value. This unit is essential for creating flexible and adaptable layouts where content adjusts automatically to changes in screen size or device layout.

Pro Tip: percentagein

Convert % to in for precise print scaling. Use % for screen adaptability.
