HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The first occurrence of ID “div-gpt-ad-1519659961110-0” was here.
Errors:
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
A slash was not immediately followed by “>”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
The “center” element is obsolete. Use CSS instead.
Duplicate ID “div-gpt-ad-1519659961110-0”.
Start tag “a” seen but an element of the same type was already open.
End tag “a” violates nesting rules.
Cannot recover after last error. Any further errors will be ignored.
