No Javascript. No images. Just conic-gradient math.
This creates a premium, rotating neon border effect for your next project.

Creating 3D objects usually requires WebGL or Three.js.

But for simple UI elements, you can build a fully rotating holographic cube using only:

transform-style: preserve-3d

Clean. Fast. No libraries.

👇 Copy Code:

<style>
  body{margin:0;height:100vh;background:#050505;display:flex;align-items:center;justify-content:center;perspective:800px}
  
  .cube{width:100px;height:100px;position:relative;transform-style:preserve-3d;animation:spin 6s infinite linear}
  
  .face{position:absolute;width:100px;height:100px;border:2px solid rgba(0,242,255,0.5);background:rgba(0,242,255,0.05);display:flex;align-items:center;justify-content:center;color:#00f2ff;font-size:12px;font-family:sans-serif;box-shadow:0 0 15px rgba(0,242,255,0.2)}
  
  /* Positioning the 6 faces */
  .front{transform:translateZ(50px)}
  .back{transform:rotateY(180deg) translateZ(50px)}
  .right{transform:rotateY(90deg) translateZ(50px)}
  .left{transform:rotateY(-90deg) translateZ(50px)}
  .top{transform:rotateX(90deg) translateZ(50px)}
  .bottom{transform:rotateX(-90deg) translateZ(50px)}
  
  @keyframes spin{0%{transform:rotateX(0deg) rotateY(0deg)}100%{transform:rotateX(360deg) rotateY(360deg)}}
</style>

<div class="cube">
  <div class="face front">FRONT</div>
  <div class="face back">BACK</div>
  <div class="face right">RIGHT</div>
  <div class="face left">LEFT</div>
  <div class="face top">TOP</div>
  <div class="face bottom">BTM</div>
</div>
