Bootstrap Carousels: A History
Carousels don’t automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they’re not explicitly required. Add and customize as you see fit.
Be sure to set a unique id on the carousel for optional controls, especially if you’re using multiple carousels on a single page.
Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards.
