WP-Validate indexes your site, collecting all the blog posts, pages and other published content, and submits it to the W3C’s HTML Validator, which then returns the response.
WP-Validate then lists the valid pages, and the invalid pages, with a link to the specific validator URL.

A plugin with common features missed in WordPress, like favicon, meta tags, adding HTML to head and footer, WordPress e-mail from header filter, etc.
I’ve developed this plugin for my own job. I’ve realized that when I create a 
new WordPress project, there are some features I have to plugin every time. I 
decided to bundle they all into a single plugin, and I’m publishing it for 
other creators who may find it useful too.
Take a look to the <a href="https://wordpress.org/extend/plugins/jb-common/changelog/" title="Go to the Changelog section" rel="ugc">Changelog</a> 
for a complete feature list, you may be interested in some of them.
