HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
A “link” element with a “sizes” attribute must have a “rel” attribute that contains the value “icon” or the value “apple-touch-icon”.
Duplicate attribute “class”.
Attribute “href” not allowed on element “span” at this point.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Attribute “href” not allowed on element “div” at this point.
The element “button” must not appear as a descendant of the “a” element.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
