Syntax

/* Keyword values */
object-fit: fill;
object-fit: contain;
object-fit: cover;
object-fit: none;
object-fit: scale-down;

/* Global values */
object-fit: inherit;
object-fit: initial;
object-fit: unset;

Values

fill
The replaced content is sized to fill the element’s content box: the object’s concrete object size is the element’s used width and height.
contain
The replaced content is sized to maintain its aspect ratio while fitting within the element’s content box: its concrete object size is resolved as a contain constraint against the element’s used width and height.
cover
The replaced content is sized to maintain its aspect ratio while filling the element’s entire content box: its concrete object size is resolved as a cover constraint against the element’s used width and height.
none
The replaced content is not resized to fit inside the element’s content box: the object’s concrete object size is determined using the default sizing algorithm with no specified size, and a default object size equal to the replaced element’s used width and height.
scale-down
The content is sized as if none or contain were specified, whichever would result in a smaller concrete object size.

Formal syntax

fill | contain | cover | none | scale-down
