HTML markup errors and warnings
(Rescan now...)
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”.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Bad element name “gcse:searchbox-only”: Code point “U+003A” is not allowed
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “navigation” role is unnecessary for element “nav”.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Element name “gcse:searchbox-only” cannot be represented as XML 1.0.
Empty heading.
This document appears to be written in English but the “html” start tag has “lang="ja"”. Consider using “lang="en"” (or variant) instead.
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).
