The inline-size
CSS property defines the horizontal or vertical size of an element's block, depending on its writing mode. It corresponds to either the width
or the height
property, depending on the value of writing-mode
.
/* <length> values */ inline-size: 300px; inline-size: 25em; /* <percentage> values */ inline-size: 75%; /* Keyword values */ inline-size: 25em border-box; inline-size: 75% content-box; inline-size: max-content; inline-size: min-content; inline-size: available; inline-size: fit-content; inline-size: auto; /* Global values */ inline-size: inherit; inline-size: initial; inline-size: unset;
If the writing mode is vertically oriented, the value of inline-size
relates to the height of the element; otherwise, it relates to the width of the element. A related property is block-size
, which defines the other dimension of the element.
