Colours.cz HTML Validation

HTML Validation Tool

Errors

Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “cz” for attribute “hreflang” on element “link”: The language subtag “cz” is not a valid ISO language part of a language tag.

Bad start tag in “img” in “head”.

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

Stray end tag “noscript”.

A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.

Stray end tag “head”.

Start tag “body” seen but an element of the same type was already open.

Cannot recover after last error. Any further errors will be ignored.
