CSS properties - inline-size

revision: December 15, 2024

inline-size property

- specifies the size of an element in the inline direction.

The related CSS property writing-mode defines inline direction, and this affects the result of the inline-size property. For pages in English, inline direction is left to right and block direction is downward.

The CSS inline-size and block-size properties are very similar to CSS properties "width" and "height", but the inline-size and block-size properties are dependent on inline and block directions.

CSS syntax : inline-size: auto | value | initial | inherit;

Property values:

auto : default. The element's default inline-size value.

length : specifies the inline-size in px, pt, cm, etc. Negative values are allowed.

% : specifies the inline-size in percent relative to size of parent element on the corresponding axis.

initial : sets this property to its default value.

inherit : inherits this property from its parent element.

JavaScript syntax : object.style.inlineSize="25vw"
