Errors:
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Stray end tag “link”.
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “br”.
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
Duplicate attribute “class”.
Bad value “tel:781-788-8180 Ext. 4” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
Warnings:
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
