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: "There is no need to modify the /platforms or /plugins folder manually unless troubleshooting needs to be done."

A block of code is set as follows:

<ion-tabs>
  <ion-tab [root]="tab1Root" tabTitle="One" tabIcon="water"></ion-tab>
  <ion-tab [root]="tab2Root" tabTitle="Two" tabIcon="leaf"></ion-tab>
  <ion-tab [root]="tab3Root" tabTitle="Three" tabIcon="flame"></ion-tab>
</ion-tabs>

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

$ sudo npm install -g cordova ionic ios-sim

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: "In this section, you will learn how to create an attribute directive that can prevent certain characters from being input in the Username as well as showing another DOM node (where it says You are typing username) by toggling its visibility."
