Trying to make a game where a word submitted shows an element

JavaScript
3

I’d be tempted to make it more generic:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title>Toggle example</title>
    <style>
      .hidden{
        display: none;
      }
    </style>
  </head>
  <body>

    <a href="#" class="toggle">Click here</a>
    <div>Now you see me</div>
    <br>
    <a href="#" class="toggle">Click here</a>
    <div>Now you see me</div>
    <br>
    <a href="#" class="toggle">Click here</a>
    <div>Now you see me</div>

    <script>
      function toggle(el){
        var target = el.nextElementSibling;

        if(target.classList.contains("hidden")){
          target.classList.remove("hidden");
        } else {
          target.classList.add("hidden");
        }
      }

      var links = document.querySelectorAll(".toggle");
      for (i = 0; i < links.length; i++) {
        links[i].addEventListener("click", function(e){
          e.preventDefault();
          toggle(this);
        })
      }
    </script>
  </body>
</html>
