HTML markup errors and warnings

Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Element “meta” is missing one or more of the following attributes: “charset”, “content”, “http-equiv”, “itemprop”, “name”, “property”.
A document must not include more than one “meta” element with its “name” attribute set to the value “description”.
Bad character “ ” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Attribute “webkitallowfullscreen” not allowed on element “iframe” at this point.
Attribute “mozallowfullscreen” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “script” must not have attribute “charset” unless attribute “src” is also specified.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
