HTML markup errors and warnings
(Rescan now...)
Errors:
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
Attribute “size” not allowed on element “input” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No space between attributes.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.
Element “li” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
The “for” attribute of the “label” element must refer to a non-hidden form control.
