To add a Carousel block, click the Toggle block inserter ( + ) in the top left corner of the Gutenberg editor and select Carousel.
A preview of the Carousel should appear containing two carousel slides.
To add additional carousel slides, click inside the Carousel and a block inserter should appear inside.
By default, the Carousel displays three spaces for carousel slides. To add additional spaces, click Number of Items per Slide under Settings within Block Settings. This will give the option of adding up to four carousel slides.
To add content, simply click to type within either the heading or description. To add additional content, click inside the carousel slide and a block inserter should appear inside.
By default, the Carousel displays the Basic Card. To change the variant of the card, select the card. Once selected, the Block Settings will appear where the variant and/or image can be updated.
If you wish to add a block within the Carousel other than a Basic or Info card, navigate to list view in the upper left corner and delete the card from the slide.
From there, a block inserter will appear within the Carousel where any block can be added.
