HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
The “center” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “h1” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “widget-category-posts-grid”.
Duplicate ID “widget-category-posts-boxed”.
Element “style” not allowed as child of element “section” in this context. (Suppressing further errors from this subtree.)
Bad value “” for attribute “src” on element “script”: Must be non-empty.
Warnings:
The “language” attribute on the “script” element is obsolete.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”.
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 first occurrence of ID “widget-category-posts-grid” was here.
The first occurrence of ID “widget-category-posts-boxed” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
