Errors

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

The element “button” must not appear as a descendant of the “a” element.

The “frameborder” attribute on the “iframe” element is obsolete.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

The first child “option” element of a “select” element with a “required” attribute, and without a “multiple” attribute, and without a “size” attribute whose value is greater than “1”, must have either an empty “value” attribute, or must have no text content. Consider either adding a placeholder option label, or adding a “size” attribute with a value equal to the number of “option” elements.

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

Unclosed element “form”.

Stray end tag “form”.

Warnings

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

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