In this book, you will 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: "Create a new folder on your computer, for example, C:Images_Nobelprize."

A block of code is set as follows:

<p><img src="http://localhost/draftfile.php/5/user/draft/317291260/Garfield_iPads.JPG" alt="iPad_Garfield_app" height="750" width="1000" />
</p>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<p>
<img src="http://localhost/draftfile.php/5/user/draft/317291260/Garfield_iPads.JPG" alt="iPad_Garfield_app" height="750" width="1000" usemap="#map" border="0"/>
</p>

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: "Right-click on the image and click on Save picture as..., as shown in the following screenshot."
