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: "However, Normalize.css makes sure that these default styles are consistent across all browsers."

A block of code is set as follows:

header h1 {
background-image: url('/img/heading-banner.png'),
width: 800px;
height: 300px;
}

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: "The following screenshot shows how the Skip Navigation link is instantly visible when the user switches keyboard focus to it."
