Errors:

Attribute “aria-selected” not allowed on element “style” at this point.
No space between attributes.
Duplicate ID “bg-box”.
Warnings:
The “border” attribute is obsolete.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The “language” attribute on the “script” element is obsolete.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.
The first occurrence of ID “bg-box” was here.
