How do I change the color and font size of my PHP?

I've been looking for ways to change the size and font of the PHP code output, but can't find a way that doesn't cause errors. I want all the following php code to appear white and enlarged:

<?php
  if (isset($_SESSION[&#39;something&#39;])) {
    echo "Welcome " . $_SESSION[&#39;something&#39;] .  ", <a href=&#39;something.php&#39;>something</a>";
  }
?>

It would be great if someone could help me achieve this. So far I've tried font color and color span with no success.

Implementation method:

Wrap the code into SPAN or DIV tags and apply some CSS styles to it.

For example:

<?php
        if (isset($_SESSION[&#39;something&#39;])){
            echo &#39;<span style="color: white; font-size: 20px;">Welcome &#39; . $_SESSION[&#39;something&#39;] .  &#39;, <a href="something.php">something</a></span>&#39;;
        }
?>
