Use aria-pressed for Toggle State Styling​

  • Use the aria-pressed attribute (set to "true" on click) as a CSS hook to style the open state.
  • Enables accessible, semantic toggling with clean CSS targeting.

Each Bar Should Be Animated Separately​

  • Treat top, middle, and bottom bars as independent elements.
  • Each bar has its own transform behavior:
    • Top: rotates and moves
    • Middle: fades out or scales
    • Bottom: rotates and moves (mirrored to top)

Chaining Transforms: Order Matters​

  • When combining transforms (e.g., translate + rotate), transform order affects the final result.
  • Transforms are applied relative to the current coordinate system, so a rotation after translation yields a different effect than vice versa.

Use Individual Transform Properties When Needed​

  • Use transform: rotate(...) translate(...) carefully when animations need precise movement.
  • To avoid issues:
    • Use separate transform properties (e.g., transform: rotate(...), transform: scale(...)) if supported by your tooling or framework.
    • Alternatively, nest elements to isolate transforms.

CSS Handles the Entire Animation​

  • The interaction is managed in JavaScript/React, but the animation itself is pure CSS.
  • No need for JS-based animation libraries for basic morphing effects.
