Hi All, Often we get clients asking us to ensure that their markup is 100% W3C valid. A recent example is Print-Print (print-print.co.uk <https://www.print-print.co.uk/>). The client in question thinks that the site needs to be totally valid in order to perform to it's max. While I know that this is not technically correct in terms of SEO etc; we need to make sure that the client is happy. Some of the issues, such as missing alt tags are the result of code passed from 3rd party companies. This site has a Feefo banner for example; which is passed through a JS snippet, but the rendered image does not have an Alt tag:- thus (rightly so) resulting in W3C Validator warnings. *Error*:An|img|element must have an|alt|attribute, except under certain conditions. For details, consultguidance on providing text alternatives for images <http://www.w3.org/wiki/HTML/Usage/TextAlternatives>. From line499, column13; to line499, column117 |*<img src="https://www.print-print.co.uk/skin/frontend/printprint/default/images/layout/feefo-gold.png" />*? | Another example could be the Google validator tag. This is a code snippet given out by Google to verify a sites ownership, yet it results in errors been rendered in the validator. *Error*:Element|meta| <http://www.w3.org/html/wg/drafts/html/master/single-page.html#the-meta-element>is missing one or more of the following attributes:|itemprop|,|property|. From line846, column1; to line846, column94 |</script>?*<meta name="google-site-verification" content="tvpJfVDs6AQx0dwl_d-Iy2Yz5cu5W14RkcWcekUiH20" />*? ?<!| The same can be seen for the Facebook verification tag. *Error*:Attribute|xmlns:fb|not allowed here. From line18, column23; to line20, column80 |E 9]><!-->*? <html class="no-js" lang="en" xmlns="http://www.w3.org/1999/xhtml"? xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml">* ?<!-- | | | | | |I would really appreciate any thoughts on this. While someone technically minded like myself can look at these errors and justify them; clients who discover the Validator and want their sites 100% valid just see errors. | |Cheers, Shaun | <https://www.postbox-inc.com/?utm_source=email&utm_medium=siglink&utm_campaign=reach>
