HTML markup errors and warnings
(Rescan now...)
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 “script”.
The “bgcolor” attribute on the “body” element is obsolete. Use CSS instead.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
The “width” attribute on the “table” element is obsolete. Use CSS instead.
The “width” attribute on the “td” element is obsolete. Use CSS instead.
The “valign” attribute on the “td” element is obsolete. Use CSS instead.
The “align” attribute on the “h1” element is obsolete.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.
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
The “border” attribute on the “table” element is obsolete. Use CSS instead.
Stray end tag “p”.
No “p” element in scope but a “p” end tag seen.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
