If you think that you've found an error in this book, please let us know about it. You will find any confirmed erratum below, so you can check if your concern has already been addressed.
On page 76:
Error in code:
<meta name="viewport" content="width=device-width;...>
The value of the "content" attribute is separated with ";" but that does not work. It should be ",".
On page 84:
The code on the page main.css is ok.
But in the source file there is missing a last ) on line 35
to(rgba(255,255,255,.05)) ) <<<<<
On page 86 and 88:
On page 86 the last parameter to addEventListener is "false" (appears twice on the page).
On page 88, the same parameter is now "true".
false was kept when testing the code and found to be working
On page 87:
The "case -90:" should set "landscape", not "portrait".
On page 92:
The code under "show ads thoughtfully" is not working well; click on the collapse ad does not show the ad.
The problem is the .ads class' "z-index:-1". Readjusting the z-index to 20 for example (and also adding a z-index : 40 to the .header-wrapper class - p.84) solves the issue.
On page 93:
Not possible to show advertising after it is closed.
The .ads style sheet has an index = -1 so you never touch it. I got it working like this:
<style>
.ads {
z-index: -1;
position: relative;
-webkit-transition: margin-top 0.35s ease-out;
border-bottom: 0;
margin: 0 auto 34px;
width: 320px;
}
.ads img { display: block; }
.tab:before {
color: red;
content: 'AD ';
}
.tab {
position: relative;
top: -34px;
background-image:-webkit-gradient(
linear, left top, left bottom,
from(black), to(#666));
color: white;
font: bold 11px/24px verdana;
height: 24px;
bottom: -24px;
left: 0;
width: 100%;
padding: 0 5px;
-webkit-box-sizing: border-box;
}
</style>
<script>
function hideAds() {
setTimeout(hide, 5000);
}
function hide() {
var ads = document.querySelector(".ads");
ads.style.marginTop = (-ads.offsetHeight) + "px";
}
function reveal() {
var ads = document.querySelector(".ads");
ads.style.marginTop = "";
hideAds();
}
</script>
</head>
<body onload="hideAds()" >
<div class="view">
<div class="header-wrapper">
<h1>Web App Header</h1>
</div>
<div class="ads">
<img src="some-ad.gif" alt="Advertising" width="320" height="50" />
</div>
<div class="tab" onclick="javascript:reveal();">

The svg spinner example is not working under iOS 4. It works fine in Safari 5.1 on Windows. No solution yet.
On page 209:
"xlink:herf" should read "xlink:href"
