Nsf.gov HTML Validation

HTML Validation Tool

Errors

Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).

Bad value “ISO-8859-1” for attribute “charset” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.

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

The “longdesc” attribute on the “img” element is obsolete. Use a regular “a” element to link to the description.

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

Warnings

The “navigation” role is unnecessary for element “nav”.

The “button” role is unnecessary for element “button”.
