HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Empty heading.
The “form” role is unnecessary for element “form”.
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 “//fonts.googleapis.com/css?family=Source+Sans+Pro:400,600,300|Kalam:400,700” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Attribute “href” not allowed on element “button” at this point.
Stray start tag “script”.
Bad value “” for attribute “src” on element “img”: Must be non-empty.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “h2” not allowed as child of element “label” in this context. (Suppressing further errors from this subtree.)
The first child “option” element of a “select” element with a “required” attribute, and without a “multiple” attribute, and without a “size” attribute whose value is greater than “1”, must have either an empty “value” attribute, or must have no text content. Consider either adding a placeholder option label, or adding a “size” attribute with a value equal to the number of “option” elements.
The “for” attribute of the “label” element must refer to a non-hidden form control.
The “aria-labelledby” attribute must point to an element in the same document.
