(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “en” for attribute “content” on element “meta”: The legacy encoding declaration did not start with “text/html;”.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
Attribute “http-equiv” not allowed on element “meta” at this point.
Bad value “screen, projection” for attribute “media” on element “style”: Deprecated media type “projection”. For guidance, see the Media Types section in the current Media Queries specification.
Element “script” must not have attribute “defer” unless attribute “src” is also specified.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.
Duplicate ID “homeBTN”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “portfolio”.
Warnings:
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The first occurrence of ID “homeBTN” was here.
The first occurrence of ID “portfolio” was here.
