HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “https://fonts.googleapis.com/css?family=Caveat:700|Poppins:400,500,600,700” for attribute “href” on element “link”: Illegal character in query: “|” is not allowed.
Element “p” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Element “div” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Duplicate ID “Layer_1”.
The “frameborder” attribute on the “iframe” element is obsolete. Use CSS instead.
The “itemprop” attribute was specified, but the element is not a property of any item.
Warnings:
The first occurrence of ID “Layer_1” was here.
