HTML markup errors and warnings
(Rescan now...)
Warnings:
The “navigation” role is unnecessary for element “nav”.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “myModalLabel” was here.
The “type” attribute is unnecessary for JavaScript resources.
This document appears to be written in Persian but the “html” start tag has “lang="en"”. Consider using “lang="fa"” (or variant) instead.
Errors:
Duplicate attribute “class”.
Element “div” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Start tag “a” seen but an element of the same type was already open.
Stray end tag “a”.
End tag “br”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Bad value “” for attribute “src” on element “img”: Must be non-empty.
The element “button” must not appear as a descendant of the “a” element.
CSS: “min-height”: only “0” can be a “unit”. You must put a unit after your number.
Duplicate ID “myModalLabel”.
End tag for “body” seen, but there were unclosed elements.
Unclosed element “div”.
