HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “menu-item-589” was here.
Empty heading.
The “contentinfo” role is unnecessary for element “footer”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “menu-item-589”.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
