Transition

The Transition component lets you add enter/leave transitions to conditionally rendered elements, using CSS classes to control the actual transition styles in the different stages of the transition.

Open in separate tab

NOTE: the transition element is published as a separate package svelte-transition

Example

<script lang="ts">
  import Transition from 'svelte-transition'

  export let show = true

  function resetIsShowing() {
    show = false
    setTimeout(() => (show = true), 500)
  }
</script>

<div class="relative m-8 flex flex-col items-center justify-center overflow-hidden rounded-xl p-16">
  <div class="h-32 w-32">
    <Transition
      {show}
      appear
      enter="duration-[400ms]"
      enterFrom="opacity-0 rotate-[-120deg] scale-50"
      enterTo="opacity-100 rotate-0 scale-100"
      leave="duration-200 transition ease-in-out"
      leaveFrom="opacity-100 rotate-0 scale-100"

If you're using TailwindUI the suggested transition classes are defined as HTML comments. Use this handy conversion tool to convert the comments into the equivalent <Transition /> element.
