What just happened?

This heading explains the working of tasks or instructions that you have just completed.

You will also find some other learning aids in the book, including:

Pop quiz—heading

These are short multiple choice questions intended to help you test your own understanding.

Have a go hero—heading

These set practical challenges and give you ideas for experimenting with what you have learned.

You will also find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "Depending on your server permissions, you may receive another prompt to create a bb-config.php file, which you can easily create using Notepad (or TextEdit for OSX) and upload using FileZilla."

A block of code is set as follows:

<div id="countdowncontainer">
<script type="text/javascript">
var futuredate=new cdtime("countdowncontainer", "December 12, 2012 12:12:12")
futuredate.displaycountdown("days", formatresults)
</script>
</div>

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: " To enable rewards points for registrations and logins, navigate to Modules under CubePoints and click on the Activate link for the Daily Points module."
