max-content

The max-content sizing keyword represents the intrinsic maximum width of the content. For text content this means that the content will not wrap at all even if it causes overflows.

Syntax

/* Used as a length */
width: max-content;
inline-size: max-content;
height: max-content;
block-size: max-content;

/* used in grid tracks */
grid-template-columns: 200px 1fr max-content;

/* Global values */
max-content: inherit;
max-content: initial;
max-content: revert;
max-content: unset;

Examples
