Bad value “//fonts.googleapis.com/css?family=Montserrat:400,700|Karla:400,700,400italic,700italic” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.

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.
Attribute “allow” not allowed on element “iframe” at this point.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.

Warnings:
The “banner” role is unnecessary for element “header”.

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).
