Stemchallenge.org HTML Check

HTML Validation Tool

Errors

Bad value “h” for attribute “media” on element “link”: Expected a CSS media type but the query ended.

Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.

Element “script” must not have attribute “charset” unless attribute “src” is also specified.

The “frameborder” attribute on the “iframe” element is obsolete.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

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

Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.

Attribute “no-repeat” not allowed on element “div” at this point.

Attribute “75px"” not allowed on element “div” at this point.

Warnings

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

Empty heading.

Attribute “75px"” is not serializable as XML 1.0.

Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
