Errors:
Internal encoding declaration “euc-jp” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=euc-jp” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Duplicate ID “navbarDropdownMenuLink”.
Stray end tag “nav”.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
End tag “section” seen, but there were open elements.
Unclosed element “div”.
Start tag “a” seen but an element of the same type was already open.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “a” at this point.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “navigation” role is unnecessary for element “nav”.
The first occurrence of ID “navbarDropdownMenuLink” was here.
Attribute “"” is not serializable as XML 1.0.
