Errors:
Missing space before doctype name.
Nameless doctype.

Bad start tag in “img” in “head”.
Stray end tag “noscript”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)

Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “br”.
Attribute “inputmode” not allowed on element “input” at this point.
The element “button” must not appear as a descendant of the “a” element.

Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “inputmode” attribute is not supported in all browsers. Please be sure to test, and consider using a polyfill.
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).
