Webtrn.cn HTML Validation

HTML Validation Tool

Errors

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

Stray end tag “meta”.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.

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

The “align” attribute on the “img” element is obsolete.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

Bad value “none” for attribute “border” on element “img”: Only “0” is a permitted zero literal.

Bad value “” for attribute “id” on element “div”: An ID must not be the empty string.

Warnings

The “type” attribute is unnecessary for JavaScript resources.

The “charset” attribute on the “script” element is obsolete.

The “language” attribute on the “script” element is obsolete.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The “border” attribute is obsolete.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The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.

Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
