Errors:
Start tag seen without seeing a doctype first. Expected “<!DOCTYPE html>”.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Stray end tag “img”.
End tag “h1” seen, but there were open elements.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Attribute “!important” not allowed on element “ul” at this point.
Warnings:
Attribute “!important” is not serializable as XML 1.0.
The “type” attribute is unnecessary for JavaScript resources.
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).
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
