4doctors.science HTML Validation

4doctors.science W3C HTML Markup Validation

HTML markup errors and warnings

(Rescan now...)

Warnings:

Consider avoiding viewport values that prevent users from resizing documents.

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

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).

Empty heading.

Attribute “"” is not serializable as XML 1.0.

The first occurrence of ID “modalLoginLabel” was here.

This document appears to be written in Spanish but the “html” start tag has an empty “lang” attribute. Consider using “lang="es"” (or variant) instead.

Errors:

A document must not include more than one “meta” element with a “charset” attribute.

A document must not include more than one “meta” element with its “name” attribute set to the value “description”.

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”.

Stray end tag “head”.

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

Stray end tag “img”.

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

Unclosed element “div”.

Stray end tag “div”.

Stray end tag “a”.

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

No space between attributes.

Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.

Attribute “"” not allowed on element “div” at this point.

“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.

Element “div” not allowed as child of element “h4” in this context. (Suppressing further errors from this subtree.)

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

Duplicate ID “modalLoginLabel”.

Attribute “"” not allowed on element “input” at this point.

Bad value “” for attribute “for” on element “label”: An ID must not be the empty string.

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

The “for” attribute of the “label” element must refer to a non-hidden form control.

The “aria-labelledby” attribute must point to an element in the same document.
