Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Stray end tag “link”.
Attribute “leftmargin” not allowed on element “body” at this point.
Attribute “topmargin” not allowed on element “body” at this point.
The “marginwidth” attribute on the “body” element is obsolete. Use CSS instead.
The “marginheight” attribute on the “body” element is obsolete. Use CSS instead.
Bad value “978px” for attribute “width” on element “img”: Expected a digit but saw “p” instead.
The “center” element is obsolete. Use CSS instead.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
The “font” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “width” attribute on the “td” element is obsolete. Use CSS instead.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
