HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Element “div” not allowed as child of element “dl” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
Element “ul” not allowed as child of element “dl” in this context. (Suppressing further errors from this subtree.)
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The “language” attribute on the “script” element is obsolete.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.
