Attribute “href” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “charset”, “content”, “http-equiv”, “itemprop”, “name”, “property”.
Bad value “https://fonts.googleapis.com/css?family=Open+Sans:600,700|Scada:400,700&subset=cyrillic” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Element “style” not allowed as child of element “body” 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.
Warnings:
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The “border” attribute is obsolete.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.
