## Styles

The markup page references an external stylesheet document.

    <!DOCTYPE html>
    <html>
      <head>
        <title>Our Solar System</title>
        <!-- the link element is used to reference a stylesheet -->
        <link rel="stylesheet" href="solarsystem.css" type="text/css"/>
        ...cut...

The CSS file contains style rules for the document (solarsystem.css)

Contents of the CSS file:
