Web Developer's Reference Guide

By: Johanan, Khan, 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.

Chapter 1. HTML Elements

HyperText Markup Language (HTML) is a language that annotates text. Annotation of text is done using elements. Using the following p element, as an example, we will see how to use HTML:

<p>This is an example</p>

HTML elements also have attributes that will modify how they are rendered or interpreted. Attributes are added inside of the starting tag. Here is the class attribute in a div element:

<div class="example">This is an example</div>

There have been multiple specifications of HTML so far, but we will just look at the most commonly used and important elements of HTML5. HTML5 is the latest official specification, so we will be as future-proof as possible at the time of writing this book. You will want to follow the specifications of HTML as closely as possible. Most browsers are very forgiving and will render your HTML, but when you go beyond the specifications, you can and will run into strange rendering issues.

Note

All HTML elements will have global attributes. The attributes listed for each element in the sections that follow are the attributes beyond the global attributes.
