Good-looking websites describe how they look in CSS files, or style sheets.

Take a look at style.css and run the code to the style sheet in action.

<html>
<head>
<style>
h1{
color: blue;  
}
p {
color: red;    
}
</style>
</head>
<body>
  <h1>Water Puns</h1>
  <p>Why does Snoop Dog need an umbrella? Fo' Drizzle.</p>
</body>
</html>
