HTML markup errors and warnings
(Rescan now...)
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Errors:
Attribute “itemprop” not allowed on element “meta” at this point.
Element “img” is missing required attribute “src”.
The “sizes” attribute may be specified only if the “srcset” attribute is also present.
The “big” element is obsolete. Use CSS instead.
Bad value “(min-width: 541px) 185w, 100w” for attribute “sizes” on element “img”: Expected units (one of “em”, “ex”, “ch”, “rem”, “vw”, “vh”, “vmin”, “vmax”, “cm”, “mm”, “q”, “in”, “pc”, “pt”, “px”) but found “w” at “(min-width: 541px) 185w,”.
No “li” element in scope but a “li” end tag seen.
