javascript - Smooth sidebar toggle animation with vuejs and tailwind

Question

I'm making a slide sidebar with vuejs and tailwind. It works but feels kind of sluggish. Is there a way to make it smoother ?

working example: https://codepen.io/tuturu1014/pen/oNzRXeW

<button @click="isOpen = !isOpen" class="bg-blue-200 p-5">
  <span v-if="isOpen">Open</span>
  <span v-else>Close</span>
</button>
<div class="flex flex-row max-w-7xl mx-auto min-h-screen">
  <transition name="slide">
    <div class="flex flex-col w-64  shadow-xl sm:rounded-lg bg-blue-200" v-if="isOpen">
      <div class="min-h-screen">sidebar</div>
    </div>
  </transition>

  <div class="flex w-full  min-h-screen bg-red-400">
    content
  </div>
</div>
<style>
  .slide-enter-active {
    animation: slideIn 1s ease;
  }
  .slide-leave-active {
    animation: slideIn 1s ease reverse;
  }
  @keyframes slideIn {
    0%   {max-width: 0%;}
    50%   {max-width: 50%;}
    100% {max-width: 100%}
  }
<style>

Answer 1

You should use transition instead of animation and target the width property :

 .slide-enter-active, .slide-leave-active {
  transition: width 1s;
}
.slide-enter, .slide-leave-to{
  width:0;
}
