HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “off-canvas” not allowed on element “div” at this point.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
Bad value “mail” for attribute “type” on element “input”.
Attribute “placeholder” is only allowed when the input type is “email”, “number”, “password”, “search”, “tel”, “text”, or “url”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
