Task guide

Use CSS tools when you need precise responsive values for typography, spacing, or layout features without writing media queries by hand. Start with the clamp calculator to define fluid type sizes and spacing across your chosen viewport range. Add safe-area-inset support after your layout is stable if your audience includes mobile users with notched screens. For iframe embeds, add responsive containers before your layout goes live to prevent overflow on small viewports. Review each generated value at your actual breakpoints, not just the viewport extremes.

Publishing checklist

  • Test generated CSS values at every breakpoint and at intermediate viewport widths where the browser transitions between them.
  • Verify clamp() values render correctly in target browsers, including browsers that do not support clamp() natively.
  • Check safe-area-inset fallbacks for devices that do not support env() variables.
  • Validate responsive embed containers with actual content, not just placeholder boxes.
  • Ensure generated CSS variable references match the names defined in your stylesheet.
