HTML validation issues #34

Open TomaszBudny opened 2 years ago

Unfortunately installing the plugin causes HTML validation issues, this can be checked in the official W3C Markup Validation Service by providing a link to a website that uses the plugin. The problems are so big that the validator service can't even recover to verify the rest of the page.

Because proper markup is a Web Content Accessibility Guidelines requirement (4.1.1 Parsing) this problem also makes businesses that use the plugin liable for litigation.

I submitted this pull request, which fixes some of the validation issues: https://github.com/facebookincubator/Facebook-Pixel-for-Wordpress/pull/35
