1.3.1 Info and Relationships

Level A

Information 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.
