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.
No space between attributes.
Bad value “tel:(888) 885-5299” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Text not allowed in element “iframe” in this context.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
Element “p” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
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).
