paddingbottom

Padding-bottom is a CSS property that defines the amount of inner space added at the bottom edge of an element’s content, inside the element’s border. It increases the distance between the content and the bottom border and can affect the element’s overall height in certain box-model configurations.

Syntax and usage: The property takes a length, a percentage, or special keywords. Examples include padding-bottom: 20px; and padding-bottom: 5%;. The longhand shorthand padding can set all four sides at once, for example padding: 8px 12px 16px 4px; The value can also be expressed with calc() for more complex calculations.

Behavior and layout considerations: Padding-bottom is not inherited by child elements. In the standard box model, increasing padding-bottom raises the element’s total height if the box sizing is content-box; if box-sizing is border-box, the specified height already includes padding, so changing padding-bottom does not change the element’s declared height. Percentage values for padding are calculated relative to the width of the containing block.

Common uses: Padding-bottom is frequently used to create breathing room inside containers, buttons, and cards. It is also used in responsive and aspect-ratio techniques, such as using padding-bottom with percentage values to preserve a desired aspect ratio for an element that scales with its width. It can work alongside other padding values to fine-tune layout and spacing.

Terminology note: The correct CSS property name is padding-bottom. In code, the property may appear as paddingBottom in JavaScript style objects, but paddingbottom without a hyphen is not standard CSS. Some libraries may convert between naming conventions, which can cause confusion.
