Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
The “border” attribute is obsolete.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The “language” attribute on the “script” element is obsolete.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.
Attribute “"” is not serializable as XML 1.0.
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).
