SVG CHAINING ANIMATIONS

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.
