WCAG 2.1·Perceivable·1.3 Adaptable
1.3.1 Info and Relationships
Level AInformation conveyed visually (headings, lists, tables, form labels) must be encoded in HTML so assistive tech can present the same structure.
Why it matters
A "heading" that is just bold text means nothing to a screen reader. Use the right element.
Common failure
<div class="heading">Pricing</div>
Accessible version
<h2>Pricing</h2>
How OnlyEnable handles this
Partially mitigated. OnlyEnable adds ARIA landmarks and roles where it can infer them, but proper HTML semantics is the right fix.
