Instructions often need some extra explanation so that they make sense, so they are followed with:
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 are practical challenges that 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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "This returns the <body> tag wrapped in a jQuery object."
A block of code is set as follows:
var x = 5; var y = 2; var z = x + y;
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
<head>
<title>Practice Page</title>
<link rel="stylesheet" href="styles/styles.css"/>
</head>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: "Just go to your browser's File menu and choose Save Page As... or right-click on the page and select Save As...."
