What is this?
ARIA adds roles, states, and properties when native HTML isn’t enough — use sparingly.
Why should you care?
MarkupVerse dialogs and tabs need careful ARIA; prefer native elements first.
See it live — copy this example
Save as demo.html and open in your browser, or use Run Example below.
<div role="dialog" aria-modal="true" aria-labelledby="dlg-title">
<h2 id="dlg-title">Confirm transfer</h2>
<button type="button">Cancel</button>
<button type="button">Confirm</button>
</div>Run Example »
Edit the code below and click Run to see the result in Toolliyo’s live editor.

- First rule: don’t use ARIA if a native element works.
