Warnings

Consider avoiding viewport values that prevent users from resizing documents.

The “banner” role is unnecessary for element “header”.

The first occurrence of ID “search” was here.

The first occurrence of ID “searchform” was here.

The first occurrence of ID “search-input” was here.

The first occurrence of ID “go_button” was here.

The “contentinfo” role is unnecessary for element “footer”.

Errors

A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.

Bad value “x-xrds-location” for attribute “http-equiv” on element “meta”.

Bad value “screen, projection” for attribute “media” on element “link”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.

Bad value “handheld” for attribute “media” on element “link”: Deprecated media type “handheld”. For guidance, see the Media Types section in the current Media Queries specification.

Attribute “alt” not allowed on element “input” at this point.

Duplicate ID “search”.

Duplicate ID “searchform”.

Duplicate ID “search-input”.

Duplicate ID “go_button”.

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

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