Web Developer's Reference Guide

By: Joshua Johanan, Talha Khan, Ricardo Zea

Overview of this book

This comprehensive reference guide takes you through each topic in web development and highlights the most popular and important elements of each area. Starting with HTML, you will learn key elements and attributes and how they relate to each other. Next, you will explore CSS pseudo-classes and pseudo-elements, followed by CSS properties and functions. This will introduce you to many powerful and new selectors. You will then move on to JavaScript. This section will not just introduce functions, but will provide you with an entire reference for the language and paradigms. You will discover more about three of the most popular frameworks today—Bootstrap, which builds on CSS, jQuery which builds on JavaScript, and AngularJS, which also builds on JavaScript. Finally, you will take a walk-through Node.js, which is a server-side framework that allows you to write programs in JavaScript.

The character set


A character set is basically a list of characters recognized by computer hardware and software. It is represented by a number. Earlier ASCII was used as standard character set encoding for web pages. There were lots of character encoding problems that were almost solved after the arrival of HTML5 and XML. JavaScript provides support for different types of languages and their characters. The character set attribute shows the character encoding in external files. For HTML5, there is a default character set encoding is UTF-8.

There are some common values of character set encoding such as the following:

  • ISO-8859-1: This is used to encode the Latin alphabet

  • UTF-8: This is used for Unicode encoding that is compatible with ASCII

For example, if your frontend page is in Spanish, and you do not use the character set property in your page, then it will not show some special characters in Spanish clearly. For this, you must declare a character set property in the top <head> tag...
