Bad value “content-style-type” for attribute “http-equiv” on element “meta”.
Bad value “content-script-type” for attribute “http-equiv” on element “meta”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “100%” for attribute “width” on element “img”: Expected a digit but saw “%” instead.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
