Cpsd.us HTML Validation

HTML Validation Tool

Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Element “meta” is missing one or more of the following attributes: “content”, “property”.

Attribute “trackingid” not allowed on element “script” at this point.

Attribute “trackingname” not allowed on element “script” at this point.

Attribute “otherdomains” not allowed on element “script” at this point.

Element “link” is missing required attribute “href”.

Bad value “android-touch-icon” for attribute “rel” on element “link”: The string “android-touch-icon” is not a registered keyword.

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

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

The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “&” instead.

Attribute “unselectable” not allowed on element “div” at this point.

Attribute “width” not allowed on element “a” at this point.

Attribute “height” not allowed on element “a” at this point.

Attribute “xmlns:dt” not allowed here.

The “aria-labelledby” attribute must point to an element in the same document.

Warnings

Consider avoiding viewport values that prevent users from resizing documents.

The “language” attribute on the “script” element is obsolete. You can safely omit it.

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

Attribute with the local name “xmlns:dt” is not serializable as XML 1.0.

Attribute with the local name “xmlns:mydate” is not serializable as XML 1.0.
