        <h3>Screen Reader</h3>
        <p>
            OverlayPanel component uses <i>dialog</i> role and since any attribute is passed to the root element you may define attributes like <i>aria-label</i> or <i>aria-labelledby</i> to describe the popup contents. In addition
            <i>aria-modal</i> is added since focus is kept within the popup.
        </p>
        <p>OverlayPanel adds <i>aria-expanded</i> state attribute and <i>aria-controls</i> to the trigger so that the relation between the trigger and the popup is defined.</p>

        <h3>OverlayPanel Keyboard Support</h3>
        <p>When the popup gets opened, the first focusable element receives the focus and this can be customized by adding <i>autofocus</i> to an element within the popup.</p>
