JSON Streaming Into a Card

JSON streams into a code pane line by line. When the closing brace lands, each value flies on an arc into its slot in a contact card, the keys dim and the card lifts with a Schema valid check.

Also known as: structured output animation, json to ui animation, ai structured output card, streaming json css.

Customizing this snippet

  • Color: set --aia-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --aia-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.
