minmax()
`minmax()` is a CSS Grid function that gives a row or column both a minimum and a maximum size.
Another example
A case grid uses `repeat(auto-fit,minmax(min(18rem,100%),1fr))`. Four cards share a row on desktop, while one card fits at 320px without making the page overflow. A very long client name wraps inside its card instead of widening the track.
Main parts
- 01Minimum track size
- 02Maximum track size
- 03Available-space distribution
Use it when
Use it to give grid tracks flexible limits instead of writing a different column width at every breakpoint.
Do not use it when
Do not put a flexible value such as `1fr` in the minimum slot. Also check the content's automatic minimum size.

Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience.
Outcome: Use or define minmax() to make the visual experience clear and easy to use. User context: A case grid uses `repeat(auto-fit,minmax(min(18rem,100%),1fr))`. Four cards share a row on desktop, while one card fits at 320px without making the page overflow. A very long client name wraps inside its card instead of widening the track. Design concept to apply: minmax(). Why it fits: Use it to give grid tracks flexible limits instead of writing a different column width at every breakpoint. Do not use it when: Do not put a flexible value such as `1fr` in the minimum slot. Also check the content's automatic minimum size. Design requirements: Set the content order, shared design values, and reusable components. Define how the layout changes by screen size and state. Keep useful design choices separate from decoration. Inclusion and resilience: Check contrast, zoom, languages, themes, and reduced motion when needed. Do not use color or effects as the only way to show meaning. Acceptance criteria: The design stays clear on phones and desktops, at zoom, in every theme, and in all supported languages. Interactive states stay clear and consistent. Evidence and limits (evidence boundary): A formal document may still be a draft, release candidate, or final version. Check its status and browser or platform support. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.
