ID unik
Mengapa penting
IDs must be unique. When the same id appears twice, labels, skip links, aria-labelledby and in-page anchors can point to the wrong element.
Cara memperbaiki
- Make every id attribute unique on the page.
- Check repeated components (cards, forms, menus) that copy the same markup.
