Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Start tag “a” seen but an element of the same type was already open.
No “p” element in scope but a “p” end tag seen.
The “align” attribute on the “p” element is obsolete. Use CSS instead.
Warnings:
The “type” attribute is unnecessary for JavaScript resources.
Empty heading.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
