The section variant of the aside element

On this page:

The aside element represents information supplementary to the main text and/or narrative flow.

The Section variant is an adaptation for use with asides that contain structured content.

An aside typically floats separate from the main text, often in a boxed or shaded region.

The role attribute optionally expresses the semantic nature of the aside.

Usage Example

<section>
    <p>Refer to the sidebar <ref ref="qisland">Quail Island</ref> for more information.</p>
    <aside xml:id="qisland" role="sidebar">
        <h>Quail Island</h>
        <section>
            <h>About</h>
            <p>Quail Island is located …</p>
        </section>
