New to JS. How can I apply CSS to this JS Fetch to alter test position, font? Thank you.

<!DOCTYPE html>
<html>
  <body>
    <p id="kdkz"></p>
    <script>
      let file = 'art.txt';

      const handleFetch = () => {
        fetch(file)
          .then((x) => x.text())
          .then((y) => (document.getElementById('kdkz').innerHTML = y));
      };

      setInterval(() => handleFetch(), 2000);
    </script>
  </body>
</html>
