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”.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Element “img” is missing required attribute “src”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “p” implied, but there were open elements.
Unclosed element “span”.
Stray end tag “span”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
