rtivelI got two w3c HTML5 validation errors on my site while the nextgen-gallery slideshow widget was activated in my 2010 child theme. Below are the errors and the fixes I did so that my site is in the green at w3c:
1. Bad value ... for attribute src on element img: DOUBLE_WHITESPACE in PATH.
...loader.gif " alt="" />
Syntax of IRI reference:
Any URL. For example: /hello, #canvas, or http://example.org/. Spaces should be escaped as %20.
Fix: remove space in line 120 of nggfunctions.php.
old -- $out .= "\n". '<img src="'. NGGALLERY_URLPATH . 'images/loader.gif " alt="" />';
new -- $out .= "\n". '<img src="'. NGGALLERY_URLPATH . 'images/loader.gif" alt="" />';
2. Error Line 128, Column 45: Required attributes missing on element script.
<script type="text/javascript" defer="defer">
Fix (line 123 of nggfunctions.php:
old -- $out .= "\n".'<script type="text/javascript" defer="defer">';
new -- $out .= "\n".'<script type="text/javascript">';
The page with the widget activated loaded as expected in firefox, opera, and IE6 with the changes.
