Colobu.com HTML Check

HTML Validation Tool

Errors

Bad value “alternative” for attribute “rel” on element “link”: The string “alternative” is not a registered keyword.

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

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

Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.

The “itemprop” attribute was specified, but the element is not a property of any item.

Warnings

Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
