Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “m_PageScroll2id” for attribute “rel” on element “a”: The string “m_PageScroll2id” is not a registered keyword.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Bad value “https://bs.serving-sys.com/BurstingPipe?
cn=ot&
onetagid=6420&
ns=1&
activityValues=$$Session=[Session]$$&
retargetingValues=$$$$&

acp=$$$$&” for attribute “src” on element “iframe”: Tab, new line or carriage return found.
Bad value “https://www.facebook.com/tr?id=180889295958498&ev=PageView
&noscript=1” for attribute “src” on element “img”: Tab, new line or carriage return found.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
