Webhook Retry Backoff

A webhook rides a rail to its endpoint and fails with an accent cross. Retries leave 1s, 2s and 4s apart on a timeline below, so the spacing shows the backoff, and the last lands with a check.

Also known as: exponential backoff animation, webhook retry animation, retry policy diagram, event delivery animation.

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.
