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”.
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.
Duplicate ID “myModalLabel”.
The “for” attribute of the “label” element must refer to a non-hidden form control.
The “aria-labelledby” attribute must point to an element in the same document.
Warnings:
The “form” role is unnecessary for element “form”.
The first occurrence of ID “myModalLabel” was here.
This document appears to be written in Czech but the “html” start tag has “lang="en"”. Consider using “lang="cs"” (or variant) instead.
