Conventions
In this book, you will find a number of text styles 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: " Add a selector for the navButton class to the media query for viewports larger than 480px."
A block of code is set as follows:
<!doctype html>
<html lang='en'>
<head>
<title>Responsive Web Design</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no">
</head>
</html>
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: " Next, launch the file in your browser. Open the Inspector (right-click, and select Inspect Element) and go to the Network Tab."
