The `fit-content` value.

The fit-content value determines an optimal dimension by considering the content of the element and the available space. Basically, fit-content chooses the best size between auto, min-content, and max-content. The exact formula is:


	min(max-content, max(min-content, <place-disponible>))

See also the explanations for the max-content and min-content values and the fit-content() function. The latter performs the same calculation as the fit-content value but allows you to set up the available space.

The `fit-content` value can be used with the following properties:

block-size : Defines the dimension of an element following the direction of the blocks.
flex-basis : Determines the default dimension of an element contained in a flex-box.
height : Sets the height of the element.
inline-size : Sets the dimension of the element in the direction of the lines.
max-height : Sets a limit for the maximum height of the element.
max-width : Sets the maximum width of the element.
min-height : Sets the minimum height of the element.
min-width : Sets the minimum width of the element.
width : Sets the width of the element.

Using `fit-content` to set the width of elements in a flex-box.

All elements in the flex-box below have a width defined by fit-content. In addition, the flex-grow and flex-shrink properties have been set to 0. We can see that fit-content behaves like max-content, i.e. the elements are sized according to their contents, without adding line breaks, and without taking into account the available width.
