=== Adding a CSS file ===
Now we want to style our content. To do this, we first have to add a link to a stylesheet in the head of index.html like so:  

<source lang="html5">
  <head>
    <title>My title</title>
    <link rel="stylesheet" type="text/css" href="style.css">
  </head>
</source>

You can see that we are linking to "style.css", so this is the file we will have to create. Open a new file in TextWrangler and add the following text:
<source lang="css">
  body{
    background: red;
  }
</source>
This makes the background of our site red, just to see if it works. Save this file as "style.css" and save it in your folder. If you open index.html in your browser again, you should see that the background is now red.
