How Do `min-content` and `max-content` Differ in CSS Sizing?

Understanding min-content and max-content in CSS Sizing

CSS sizing allows for intrinsic dimensions like min-content and max-content, which differ from extrinsic dimensions like percentages that depend on parent boxes. Intrinsic dimensions originate from the content within the box itself.

Intrinsic Dimensions of a Box

Intrinsic dimensions define the inherent size of a box based on its contents, regardless of its placement in the document.

min-content

The min-content value represents the minimum width of a box to avoid overflowing its contents. It is equivalent to the width that would occur if the box floated with zero width for its parent box. For instance, #red { width: min-content } would give the same width as #blue { float: left; #blue > #red { width: 0px } }. In this scenario, min-content ensures the text inside #red doesn't overflow.

max-content

max-content calculates the ideal width for a box with infinite available space. It represents the minimum size where the box fits around its contents without overflowing while minimizing empty space. Similarly to min-content, we can demonstrate this using float: #blue { float: left; #blue > #red { width: max-content } }. In this case, max-content allows #red to fully utilize the available space on the x-axis within #blue without overflowing.

Status of Other Properties

Properties like fit-content and stretch are still in development and their specifications may change in the future. They will be added to this discussion once they reach a more stable state.
