no-ineffective-attr

info

🔧 This rule supports auto-fix with the --fix option.

Warn that if the attribute specified cannot affect (in other words, mean-less) the element.

info

Not included in any preset: markuplint:html-standard only admits rules for a HTML LS MUST; an ineffective (but not disallowed) attribute is non-normative.
