HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The first occurrence of ID “” was here.
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Errors:
Bad value “https://fonts.googleapis.com/css?family=Open+Sans:300,300i,400,400i,600,700|PT+Serif:400,400i,700,700i&subset=cyrillic&display=swap” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Stray end tag “i”.
Bad value “” for attribute “id” on element “a”: An ID must not be the empty string.
Duplicate ID “”.
Stray end tag “a”.
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
The “language” attribute on the “script” element is obsolete. Use the “type” attribute instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
