HTML markup errors and warnings
(Rescan now...)
Warnings:
Documents should not use “about:legacy-compat”, except if generated by legacy systems that can't output the standard “<!DOCTYPE html>” doctype.
Consider avoiding viewport values that prevent users from resizing documents.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Errors:
Element “div” not allowed as child of element “strong” in this context. (Suppressing further errors from this subtree.)
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Bad value “//googleads.g.doubleclick.net/pagead/viewthroughconversion/ 939024691/?value=0&guid=ON&script=0” for attribute “src” on element “img”: Illegal character in path segment: space is not allowed.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Bad value “true” for attribute “async” on element “script”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
