HTML markup errors and warnings
(Rescan now...)
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “b-sign-in”.
End tag “li” seen, but there were open elements.
Unclosed element “div”.
Attribute “js-video-source” not allowed on element “div” at this point.
Attribute “js-video-width” not allowed on element “div” at this point.
Attribute “js-video-height” not allowed on element “div” at this point.
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
The “big” element is obsolete. Use CSS instead.
Attribute “alt” not allowed on element “div” at this point.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “<” instead.
Warnings:
The first occurrence of ID “b-sign-in” was here.
