(Rescan now...)
Errors:
Bad value “Cache-control” for attribute “http-equiv” on element “meta”.
Bad value “Expires” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
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.
Bad value “” for attribute “id” on element “div”: An ID must not be the empty string.
Duplicate ID “”.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Bad value “150px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Element “img” is missing required attribute “src”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Warnings:
The first occurrence of ID “” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
