Validation Output: 6 Errors
Line 37, Column 17: Element style not allowed as child of element noscript in this context. (Suppressing further errors from this subtree.)
<noscript><style>#metadata_window {display:block !important} </style></noscript>
Contexts in which element style may be used:
If the scoped attribute is absent: where metadata content is expected.
If the scoped attribute is absent: in a noscript element that is a child of a head element.
If the scoped attribute is present: where flow content is expected, but before any other flow content other than inter-element whitespace, and not as the child of an element whose content model is transparent.
Content model for element noscript:
When scripting is disabled, in a head element: in any order, zero or more link elements, zero or more style elements, and zero or more meta elements.
When scripting is disabled, not in a head element: transparent, but there must be no noscript element descendants.
Otherwise: text that conforms to the requirements given in the prose.
