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, folder names, filenames, file extensions, pathnames, URLs, and user input are shown as follows: "You can name the folder whatever you like, but we'll refer to it as the sandbox folder."

A block of code is set as follows:

var map = new ol.Map({
  target: 'map',
  layers: [layer],
  view: view
});

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

var map = new ol.Map({
 target: 'map',
 view: view,
 layers: [layer],
 renderer: 'dom'
});

Any command-line input or output is written as follows:

weinre –boundHost <your ip address>

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: "You can do this in several ways but the easiest is to load your page into a web browser and look at the Network tab".
