Architecture & Privacy

  • Bi-directional Main & Cross Axis simulation: Accurately reflects flexbox layout physics in real time.
  • Individual Item Control: Test flex-grow, flex-shrink, and align-self overrides on specific child elements.
  • Instant Tailwind Mapping: Translates CSS flex rules into standard Tailwind flex-* and justify-* utility classes.
  • Dynamic Item Counter: Add up to 12 responsive items to test wrapping behavior under realistic constraint loads.
