Conventions

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: "The on load property is responsible to invoke the init() function."

A block of code is set as follows:

<html>
<head>
  <title>Simple Lines</title>
    <script type="text/javascript">
      var can;
      var ctx;

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

function drawHorizontalLines()
      {
        xs=10;  ys=10;xe=100; ye=10;
        c="teal"; w=2;  
        //draw 10 lines

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: "If your browser doesn't support Canvas then it will display Your browser doesn't support Canvas as mentioned in the Canvas element of the HTML code."

Note

Warnings or important notes appear in a box like this.
