CSS Clamp Generator & Playground

This little lab gadget takes the mystery out of clamp() and turns it into something you can actually use without opening a spreadsheet. Set your min/max viewport widths, dial in the smallest and largest sizes you want, and it builds a perfectly smooth fluid value that scales exactly how you expect. You get a live preview, clean copy-and-paste CSS, and optional presets for headings, body text, and spacing. Plus, guidance on how your fluid value is worked out - missing from most tools.
