HTML markup errors and warnings
(Rescan now...)
Errors:
A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad start tag in “img” in “head”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
The element “a” must not appear as a descendant of the “button” element.
Element “input” with attribute “type” whose value is “button” must have non-empty attribute “value”.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
