HTML Validation Tool

Errors

Quirky doctype. Expected “<!DOCTYPE html>”.

The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.

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”.

The “bgcolor” attribute on the “body” element is obsolete. Use CSS instead.

The “width” attribute on the “table” element is obsolete. Use CSS instead.

The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.

The “border” attribute on the “table” element is obsolete. Use CSS instead.

The “width” attribute on the “td” element is obsolete. Use CSS instead.

The “align” attribute on the “td” element is obsolete. Use CSS instead.

The “font” element is obsolete. Use CSS instead.

The “valign” attribute on the “td” element is obsolete. Use CSS instead.

The “bgcolor” attribute on the “table” element is obsolete. Use CSS instead.

The “align” attribute on the “p” element is obsolete. Use CSS instead.

Bad element name “gcse:searchbox-only”: Code point “U+003A” is not allowed

No “p” element in scope but a “p” end tag seen.

Element “g:plusone” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)

The “align” attribute on the “img” element is obsolete.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 “table” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)

Stray end tag “d”.

Table cell spans past the end of its row group established by a “tbody” element; clipped to the end of the row group.

End tag “p” implied, but there were open elements.

Unclosed element “font”.

Unclosed element “span”.

End tag “p” seen, but there were open elements.

Element “p” not allowed as child of element “font” in this context. (Suppressing further errors from this subtree.)

The “align” attribute on the “div” element is obsolete.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The “name” attribute on the “img” element is obsolete.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.

Stray end tag “span”.

Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)

Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)

The “bgcolor” attribute on the “td” element is obsolete. Use CSS instead.

Stray end tag “a”.

End tag “td” seen, but there were open elements.

The “align” attribute on the “table” element is obsolete. Use CSS instead.

Bad value “mailto:comments@theoremoftheday.org?subject=Theorem of the Day” for attribute “href” on element “a”: Illegal character in query: space is not allowed.

Element “area” is missing required attribute “alt”.

Warnings

The “language” attribute on the “script” element is obsolete. You can safely omit it.

Element name “gcse:searchbox-only” cannot be represented as XML 1.0.

Element name “g:plusone” cannot be represented as XML 1.0.

The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.

The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

A table row was 3 columns wide, which is less than the column count established by the first row (4).

This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
