HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Unsupported SVG version specified. This validator only supports SVG 1.1. The recommended way to suppress this warning is to remove the “version” attribute altogether.
The first occurrence of ID “Layer_1” was here.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
Errors:
Bad value “true” for attribute “novalidate” on element “form”.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
Bad value “tel:+1 646-568-7851” for attribute “href” on element “a”: Illegal character in scheme data: space is not allowed.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
Duplicate ID “Layer_1”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
