You can emulate a "zoom" into a div with CSS transform: scale() property. Here's some JS code that toggles between a zoomed in/out state on click.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
    <title>Testing</title>
    <style>
      #zoom {
        height: 50px;
        width: 50px;
        margin: auto;
        margin-top: 100px;
      }
    </style>
  </head>
  <body>
    <div class="container">
      <div id="zoom"><p>Test</p></div>
    </div>
    <script>
      // On click, scale up or down
      document.getElementById("zoom").addEventListener("click", function() {
        this.style.transform === "scale(2)"
          ? (this.style.transform = "scale(1)")
          : (this.style.transform = "scale(2)");
      });
    </script>
  </body>
</html>

You can add transition CSS for smooth zoom in/out.

    transition: transform 2s;
  -webkit-transition: transform 2s;
