Web Developer's Reference Guide

4.7 (3)
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 size of the page box cannot be modified. But if we plan to modify some of the page box properties, we need to include them in an @page rule.

Let's check it out.

The bleed CSS property is also called the CSS at-rule descriptor. It defines how much a page should "overflow" or bleed outside the page box. This property only works if marks have been enabled using the marks property, which we'll see next.

Description

CSS:

}

marks
