Chemistry-expo.ru HTML Check

HTML Validation Tool

Errors

Legacy encoding “windows-1251” used. Documents must use UTF-8.

Internal encoding declaration “utf-8” disagrees with the actual encoding of the document (“windows-1251”).

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

Attribute “block_id” not allowed on element “span” at this point.

Attribute “sys_name” not allowed on element “span” at this point.

Attribute “tarea_id” not allowed on element “span” at this point.

Attribute “name” not allowed on element “meta” at this point.

Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.

A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “modulepreload”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.

Stray end tag “head”.

Start tag “body” seen but an element of the same type was already open.

Duplicate ID “rbccontents_ee_block”.

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

The “align” attribute on the “img” element is obsolete.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

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

Duplicate attribute “class”.

Duplicate attribute “href”.

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

The “align” attribute on the “h2” element is obsolete. Use CSS instead.

The “align” attribute on the “div” element is obsolete.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

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

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

The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.

Duplicate ID “text”.

Attribute “weight” not allowed on element “img” at this point.

Bad value “29px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.

Warnings

The first occurrence of ID “rbccontents_ee_block” was here.

The “border” attribute is obsolete.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

The “type” attribute is unnecessary for JavaScript resources.

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

The first occurrence of ID “text” was here.
