Hi there,

I was checking over a site I have recently been working on to see how it
validates against the HTML5 spec and I think I may have found a bug.

Put simply the validator is telling me the following:

[image: Error] *Line 119, Column 136*: Duplicate attribute class.

…script-open-a-maximised-window/" class*=*"articleTitle">Javascript open a maxim


For example, unless I'm missing something I'm not sure it should be
reporting this for the element/line specified. The URL in question is '
http://www.dougmcdonald.co.uk/test/html5/v5/articles/' and an example of the
html which is being output and supposedly the cause of the above validation
error is below:

<article class="blog">
<header>
<h2>
<a class="articleTitle" href="
http://www.dougmcdonald.co.uk/test/html5/v5/2011/09/08/Javascript-open-a-maximised-window/
">Javascript open a maximised window</a>
</h2>

</header>
<div class="excerpt"> Often people ask how to open a new window 'maximised'
from client side Javascript. With this in mind, below is a function to open
a new window about a ... </div>
</article>

Unless I'm going mad, that element doesn't include a duplicate class
attribute. It feels like I'm missing something, in which case, please
discard this! if it's of any help identifying a bug though, then hopefully
the info above will be useful.

Many thanks,

Doug
