Red color font view source page

Question

In my view source page below lines are in red color.

<img alt="4054775 1991 Chevrolet Camaro" class="image" onerror="this.onerror=null;this.src='/images/nophoto_250.gif'"; 
src="http://carphotos3.cardomain.com/images/0016/35/82/16355328_large.jpg"   />

I think

onerror="this.onerror=null;this.src='/images/nophoto_250.gif'";

is incorrect. Or else why these lines are in red color??

Thanks

That (`onerror`) isn't a valid attribute of an `img` tag, but that appears to be how they prevent broken images link from loading in their page. — Elliott Frisch, Jun 25 '14 at 07:08
Compulsory? No. Violations are met with a stern talking to by the secrete committee on... Perhaps I've said too much. — Elliott Frisch, Jun 25 '14 at 07:14
or can i use something else to prevent broken img?? it is difficult to remove **onerror** in all pages in my website. — user3725640, Jun 25 '14 at 07:14

First of all remove semi-colon after onerror

use html doctype proper

<!DOCTYPE html>
<html>
<head>

</head>
<body> 
<p>If you click on me, I will disappear.</p> 
<p>Click me away!</p>
<p>Click me too!</p>
