Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Attribute “"” is not serializable as XML 1.0.
The first occurrence of ID “lnb-pc” was here.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Attribute “;” is not serializable as XML 1.0.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “div” at this point.
Duplicate ID “lnb-pc”.
Stray end tag “span”.
Attribute “;” not allowed on element “a” at this point.
Stray end tag “a”.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
End tag “div” seen, but there were open elements.
Unclosed element “button”.
Bad character “개” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
The “width” attribute on the “col” element is obsolete. Use CSS instead.
Element “caption” not allowed as child of element “table” in this context. (Suppressing further errors from this subtree.)
