HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “form” role is unnecessary for element “form”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
This document appears to be written in Polish. Consider adding “lang="pl"” (or variant) to the “html” start tag.
Errors:
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value for attribute “href” on element “a”: Percentage ("%") is not followed by two hexadecimal digits.
Element “div” not allowed as child of element “h1” in this context. (Suppressing further errors from this subtree.)
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “<” instead.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Element “ul” not allowed as child of element “ul” in this context. (Suppressing further errors from this subtree.)
Element “script” must not have attribute “async” unless attribute “src” is also specified.
Bad value “https://www.facebook.com/tr?id=803254963187136&ev=PageView
&noscript=1” for attribute “src” on element “img”: Tab, new line or carriage return found.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
