Nadca.com HTML Check

HTML Validation Tool

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.

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

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

Element “h2” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)

Duplicate attribute “class”.

End tag “p” seen, but there were open elements.

Unclosed element “span”.

End tag “a” violates nesting rules.

Stray end tag “span”.

The “frameborder” attribute on the “iframe” element is obsolete.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

Bad value “” for attribute “name” on element “button”: Must not be empty.

Stray end tag “div”.

End tag for “body” seen, but there were unclosed elements.

Unclosed element “section”.

Warnings

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

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.

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