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 are shown as follows: "Try changing the background color."

A block of code is set as follows:

*, body{margin:0;padding:0}
#maintenance
{
width:450px;
margin:35px auto 0 auto;
padding:12px 0;
background:#fff;
text-align:center;
text-transform:none;
font-weight:normal;
letter-spacing:0;
color: #C73178;
}

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

#maintenance
{
width:750px;
margin:35px auto 0 auto;
padding:12px 0;
background:#fefefe;
text-align:center;
text-transform:none;
font-weight:bold;
letter-spacing:0;
color: #3FCA66;
}

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: "Click on the Save button".
