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 “” for attribute “id” on element “div”: An ID must not be the empty string.
Bad value “https://bs.serving-sys.com/BurstingPipe/adServer.bs?cn=rsb&c=28&pli=23165782&PluID=0&w=300&h=250&ord=[timestamp]&ucm=true” for attribute “src” on element “script”: Illegal character in query: “[” is not allowed.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “https://bs.serving-sys.com/BurstingPipe/adServer.bs?cn=rsb&c=28&pli=23163270&PluID=0&w=300&h=250&ord=[timestamp]” for attribute “src” on element “script”: Illegal character in query: “[” is not allowed.
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Bad value “300px” for attribute “width” on element “iframe”: Expected a digit but saw “p” instead.
Bad value “183px” for attribute “height” on element “iframe”: Expected a digit but saw “p” instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
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).
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
