Errors:
The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.
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.
No “p” element in scope but a “p” end tag seen.
Attribute “datatype” not allowed on element “a” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in either Croatian, Serbian, or Bosnian, but the “html” start tag has “lang="en-us"”. Consider using either “lang="hr"”, “lang="sr"”, or “lang="bs"” instead.
