Iso.fr HTML Check

HTML Validation Tool

Errors

Attribute “target” not allowed on element “img” at this point.

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 “div”.

No “p” element in scope but a “p” end tag seen.

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

Bad value “0” for attribute “allowfullscreen” on element “iframe”.

The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.

Warnings

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

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

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

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

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).

The “type” attribute is unnecessary for JavaScript resources.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

This document appears to be written in French. Consider adding “lang="fr"” (or variant) to the “html” start tag.
