AI CSS Animations

Git Branch and Merge

An accent branch grows off the main line of an isometric commit graph, gains two commits and merges back with a ring pulse, on a dot grid. SVG lines grown with CSS scale.

Also known as: git branch animation, git merge diagram, hairline isometric.

Customizing this snippet

  • Color: set --hln-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --hln-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • 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.
