HTML markup errors and warnings
(Rescan now...)
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
The first occurrence of ID “navbarDrop1” was here.
Text run is not in Unicode Normalization Form C.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Attribute “"” is not serializable as XML 1.0.
This document appears to be written in English but the “html” start tag has an empty “lang” attribute. Consider using “lang="en"” (or variant) instead.
Errors:
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
Duplicate ID “navbarDrop1”.
Element “a” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “marquee” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Bad value “images/slides/Bangabandhu sriti.jpg” for attribute “src” on element “img”: Illegal character in path segment: space is not allowed.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No space between attributes.
Saw “"” when expecting an attribute name. Probable cause: “=” missing immediately before.
Attribute “"” not allowed on element “a” at this point.
