HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “100%” for attribute “height” on element “img”: Expected a digit but saw “%” instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Stray end tag “i”.
The “scrolling” attribute on the “iframe” element is obsolete. Use CSS instead.
The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Warnings:
Empty heading.
Potentially bad value “allow-scripts allow-same-origin” for attribute “sandbox” on element “iframe”: Setting both “allow-scripts” and “allow-same-origin” is not recommended, because it effectively enables an embedded page to break out of all sandboxing.
The “type” attribute is unnecessary for JavaScript resources.
The “charset” attribute on the “script” element is obsolete.
Consider adding a “lang” attribute to the “html” start tag to declare the language of this document.
