3D Text Cube Rotation

Two words sit on the faces of a 3D box that rolls a quarter turn upward, holds, then rolls again with a springy settle. Four faces placed with rotateX and translateZ inside a preserve-3d box.

Also known as: rotating cube text css, 3d cube words, text on cube faces.

Customizing this snippet

  • Color: set --txt-color on the element or a parent. Currently previewing #3b82f6.
  • Font size: set --txt-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 40px.
  • Speed: change the duration on the transition or animation shorthand. 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.
