clamp()
`clamp()` chooses a preferred CSS value but keeps it between a minimum and a maximum.
Another example
A headline uses `clamp(2rem,1.2rem + 3vw,4.5rem)`. It grows smoothly from phone to desktop, but never goes below 32px or above 72px. Because the rule keeps `rem` units, browser zoom still works.
Main parts
- 01Minimum
- 02Preferred expression
- 03Maximum
Use it when
Use it for a value that should change smoothly but stay inside clear, readable limits. Mix relative and viewport units when helpful.
Do not use it when
For text, do not make the preferred value use only viewport units. Test zoom, short screens, and very long translations.

clamp(minimum, preferred, maximum) Before you ship
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 clamp() to make the visual experience clear and easy to use. User context: A headline uses `clamp(2rem,1.2rem + 3vw,4.5rem)`. It grows smoothly from phone to desktop, but never goes below 32px or above 72px. Because the rule keeps `rem` units, browser zoom still works. Design concept to apply: clamp(). Why it fits: Use it for a value that should change smoothly but stay inside clear, readable limits. Mix relative and viewport units when helpful. Do not use it when: For text, do not make the preferred value use only viewport units. Test zoom, short screens, and very long translations. 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.
