Errors:
Bad value “” for attribute “href” on element “link”: Must be non-empty.
Bad value “https://fonts.googleapis.com/css?family=Source+Sans+Pro:300,400,600,700|Montserrat:300,400,700” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Bad value “https://api.w.org/” for attribute “rel” on element “link”: The string “https://api.w.org/” is not a registered keyword.
Element “div” not allowed as child of element “button” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
No “p” element in scope but a “p” end tag seen.
Bad value “50px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
Warnings:
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Empty heading.
This document appears to be written in English. Consider adding “lang="en"” (or variant) to the “html” start tag.
