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: "nofollow is a possible value for the rel attribute inside the<a> tag."

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: "On the right-hand side of the site page is a section named SEO Settings, as seen in the next screenshot."
