object-fit take Value description
object-fit is mainly suitable for replacing elements, such as: , , , , < ;svg:video>etc. Its default value is fill. The description of the object-fill value is as follows:
fill: This value is the default value of boject-fit. The size of the replacement content is set to the content box of the filling element, that is, The element's content expands to completely fill the container's outer dimensions, even if this breaks its intrinsic aspect ratio.
contain: Replace the element content size to maintain the aspect ratio to fill the element content container, and its specific object size is parsed as the width and height of a containing element. That is, if you set an explicit height and width on the replacement element, this value will cause the content to be sized exactly at the fixed ratio, but still within the element dimensions.
cover: Replace the element content size to maintain the aspect ratio to fill the element content container, and its specific object size is parsed to cover the width and height of the entire element. That is, the replacement element content size maintains the aspect ratio, but changes the width and height so that it completely covers the content element.
none: The replaced element content does not resize to fit the container of the inner element, the content completely ignores any height and weight set on the element and remains within the element Shown within dimensions.
scale-down: When the content size is set to non or contain, the specific object will become larger. Small.
