Animating a background moving between grid elements

I made this simple switch but I wanna animate the background moving from left to right instead of having it disappear and reappear. Right now the background is just a css class applied when the item is active, but I was thinking of creating a grid item that overlaps the other two with the same width to achieve this. Couldn't get it working though, any tips on how I can do this? This is my current component

<script lang="ts" setup>
defineProps<{
  first: string
  second: string
}>()
const enabled = ref(false)

function toggle() {
  enabled.value = !enabled.value
}
</script>

<template>
  <Switch
    v-model="enabled"
    class="relative grid grid-cols-2 bg-grey-900 gap-2 border-box-border rounded-full border p-1 cursor-pointer"
    @click="toggle"
  >
    <span
      class="select-none text-center rounded-full px-2 py-1 text-xs transition-all"
      :class="enabled ? 'bg-purple-500' : ''"
    >{{ first }}</span>
    <span
      class="select-none text-center rounded-full px-2 py-1 text-xs transition-all"
      :class="!enabled ? 'bg-purple-500' : ''"
    >{{ second }}</span>
  </Switch>
</template>

Basically something like this but for the background

I don't know that you need to use grid for this (the example below doesn't use grid).

hopefully that's helpful 😄

GiuliopimeOP•9mo ago

that's fixed width unfortunately but thank you

Mike•9mo ago

yep, it's fixed width right now, but can you think of any way to make this work for dynamic width buttons?
