I'm trying to draw CSS animation lines that aren't rendering-CodePudding

As the title suggests, I am trying to create an animation that draws an infinite line loop around a button I have created yet it isn't rendering for some reason. Below is my CSS and HTML Code.

<!DOCTYPE HTML>

      <link rel="stylesheet" href="style.css">

<div >
<body>
  
    <h2>Which Person Are You Looking For?</h2>
    <form>
      <a href ="/home/chimera/Documents/k13c/fail/jr/index.html" >Jr</a>
      <a href="#" >Sr</a>
    </form>
  </div>
</body>

    width: 2px;
    height: 100%;
    background: linear-gradient(360deg, transparent, #03e9f4);
    animation: btn-anim4 1s linear infinite;

  }
  
  @keyframes btn-anim4 {
    0% {
      bottom: -100%;
    }
    50%,100% {
      bottom: 100%;
    }
  }
  
  

  .Jr{
    left: 50px;
  }

  .Sr{
    left: 140px;
  }

I have tried changing it such that the lines are rendered at all but to no avail and can't find how to get them to render, my code is a fork of this and I am trying to create the animation around the submit button on both the Sr and Jr buttons showed.

You forget to add "span" tag inside the a tag.
