Bootstrap 5 Accordion
| Term | Description |
|---|
| Flush | Adding the .accordion-flush class removes default background color, borders, and some rounded corners from accordions, rendering them edge-to-edge with their parent container. | | Always Open | Omitting the data-bs-parent attribute makes accordion items stay open when another item is opened. | | SASS | Changing default accordion values using Bootstrap 5 SASS variables. |
