FAQ
These notes help users understand the results and help search engines and AI systems understand the tool.
clamp 字体公式解决什么问题？
它让字体在最小值和最大值之间随视口线性变化，避免只靠媒体查询切换造成跳变。
可以直接复制到 CSS 吗？
可以复制生成的 clamp()，但上线前仍应在项目断点、浏览器缩放、中文长词和按钮容器里做视觉回归。
Can a CSS clamp font-size replace media queries?
It can remove many font-size breakpoints, but layout, line-height, button text, and wrapping still need responsive testing.
Why enter min and max viewport widths?
They define where the font starts and stops scaling so type does not become too small or too large on extreme screens.
