Warnings:
The character encoding “gb2312” is not widely supported. Better interoperability may be achieved by using “UTF-8”.
Using “gbk” instead of the declared encoding “gb2312”.
The “type” attribute is unnecessary for JavaScript resources.
The first occurrence of ID “dataroll” was here.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
Errors:
Legacy encoding “gbk” used. Documents must use UTF-8.
Bad value “text/html; charset=gb2312” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
Attribute “border” not allowed on element “iframe” at this point.
Bad value “100%” for attribute “width” on element “iframe”: Expected a digit but saw “%” instead.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The “marginwidth” attribute on the “iframe” element is obsolete. Use CSS instead.
The “marginheight” attribute on the “iframe” element is obsolete. Use CSS instead.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Duplicate ID “dataroll”.
Bad value “260px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
Bad value “230px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
