Description
The fit-content operates using an intelligent clamping mechanism. It computes the size of an element using the following logic:
fit-content size=min(max-content,max(min-content,available-space))
Motivation
The current description of fit-content does not clearly explain how its sizing logic works internally. This update introduces a concise explanation of the clamping mechanism behind fit-content, including the formula used to compute the final size. It helps developers better understand how the function balances content size and available space, especially in responsive layouts.
