Hamburger Menu to X Hover
Three bars that slide together and then cross into an X, while the middle bar shrinks away. Separate translate and rotate transitions run in sequence, reversed on the way back.
Also known as: hamburger menu animation css, menu icon to close icon, burger icon hover.

}Customizing this snippet
- Color: set
--hfx-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--hfx-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
