Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
Element “area” is missing required attribute “alt”.
Duplicate ID “topic_img_130517”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
