When the “srcset” attribute has any image candidate string with a width descriptor, the “sizes” attribute must also be present.
Attribute “about” not allowed on element “div” at this point.
The “align” attribute on the “img” element is obsolete. Use CSS instead.
Attribute “alt” not allowed on element “input” at this point.
Duplicate ID “SURVEY_ID”.
Warnings:
The “banner” role is unnecessary for element “header”.
The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
