Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
A “charset” attribute on a “meta” element found after the first 1024 bytes.
A document must not include more than one “meta” element with a “charset” attribute.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Bad value “100%” for attribute “width” 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.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in Turkish but the “html” start tag has an empty “lang” attribute. Consider using “lang="tr"” (or variant) instead.
