Schoolbordportaal.nl HTML Check

HTML Validation Tool

Errors

Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)

Obsolete doctype. Expected “<!DOCTYPE html>”.

When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.

The “version” attribute on the “html” element is obsolete. You can safely omit it.

The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.

Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)

The element “input” must not appear as a descendant of the “a” element.

Bad value “” for attribute “for” on element “label”: An ID must not be the empty string.

The element “label” must not appear as a descendant of the “a” element.

Bad value for attribute “href” on element “a”: Illegal character in query: “[” is not allowed.

The “center” element is obsolete. Use CSS instead.

The “border” attribute on the “table” element is obsolete. Use CSS instead.

The “valign” attribute on the “td” element is obsolete. Use CSS instead.

Bad value “138px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

No “p” element in scope but a “p” end tag seen.

Element “script” must not have attribute “charset” unless attribute “src” is also specified.

The “for” attribute of the “label” element must refer to a non-hidden form control.

Warnings

Empty heading.
