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.

CSS counters, on the other hand, take styling lists (or any element for that matter) to a whole new level of customization and styling.

Granted, CSS counters rely not only on the properties we're going to see next, but also on the content property and the :before pseudo-element.

Let's check out the properties that make CSS counters so great.

counter-reset

The counter-reset CSS property resets the counter by giving it a name, and it looks like this:

counter-reset: basic-counter;

Description

The counter-reset property serves two purposes: resets the counter and defines a name for the counter. The name is later used by the counter-increment and counter()/counters() functions that we'll see later.

I have to admit that the term "counter-reset" isn't as intuitive as it should be if it's...
