Along with my co-lead author, Kyle Simpson, I congratulate and thank the contributors to the HTML5 Cookbook: Emily Lewis, Kimberly Blessing, Christina Huggins Ramey, Anitra Pavka, Marc Grabanski, and Christopher Deustch. The gentleman's name is "Deutsch", not "Deustch".

After 4th paragraph

Book: "HTML5 Canvas" Chapter: "Chapter 1 - Introduction to HTML5 Canvas" Section: "Testing to See Whether the Browser Supports Canvas" Page: 10 ==================================================================== The code following the 4th paragraph on page 10 shows a function named "canvasSupport", which reads as: --- function canvasSupport () { †††return !!document.createElement('testcanvas').getContext; } --- There is no tag named "testcanvas" in HTML5. I believe you mean to create a "canvas" element, and so the code should read: --- function canvasSupport () { †††return !!document.createElement('canvas').getContext; } --- Note that "testcanvas" is replaced by "canvas".

Note from the Author or Editor:
change "testcanvas" to "canvas"

The end Line 2 on this page refers to Chapter 8 for the Local Storage API when this is actually referenced in Chapter 10.

3rd and 4th paragraphs

When the audio element isnít supported, Modernizr adds a no-audio class to the header element. [...] When the audio element is supported, however, Modernizr adds the audio class to the header element. I think it should read in both cases "to the HTML (root) element", instead of header-element.

Note from the Author or Editor:
change "header element" to "<html> element"

First code sample under "Discussion"

Book: "HTML5 Cookbook" Chapter: "Chapter 5 - Native Video" Section: "5.6 Sample Design: Manipulating Video with <canvas>" Page: 126 ================================================================ The code shown in Discussion has a typo. A javascript line in the function "generatePreview" has a typo in the parameter passed to "getElementById". The line reads: var canvas2 = document.getElementById('previewsSm'); The id is actually "previewSm" (which is the id shown for the markup tag "canvas"), and so the line should read: var canvas2 = document.getElementById('previewSm');

Note from the Author or Editor:
change "previewsSm" to "previewSm"
