Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “form” role is unnecessary for element “form”.
This document appears to be written in Turkish but the “html” start tag has “lang="en"”. Consider using “lang="tr"” (or variant) instead.
Errors:
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “sumit” for attribute “type” on element “button”.
Element “img” is missing required attribute “src”.
No “p” element in scope but a “p” end tag seen.
Named character reference was not terminated by a semicolon. (Or “&” should have been escaped as “&”.)
The “aria-labelledby” attribute must point to an element in the same document.
