HTML markup errors and warnings
(Rescan now...)
Warnings:
The “main” role is unnecessary for element “main”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
Bad value “” for attribute “width” on element “img”: The empty string is not a valid non-negative integer.
Bad value “” for attribute “height” on element “img”: The empty string is not a valid non-negative integer.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Element “object” is missing one or more of the following attributes: “data”, “type”.
The “classid” attribute on the “object” element is obsolete. Use the “data” and “type” attributes to invoke plugins. To set a parameter with the name “classid”, use the “param” element.
The “codebase” attribute on the “object” element is obsolete. Use the “data” and “type” attributes to invoke plugins. To set a parameter with the name “codebase”, use the “param” element.
Stray end tag “embed”.
Bad value “_slef” for attribute “target” on element “a”: Reserved keyword “slef” used.
Bad character “%” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Element “param” not allowed as child of element “object” in this context. (Suppressing further errors from this subtree.)
