Carousel(Slide) by query loop?

Dear Support,

According to the previous thread https://generatepress.com/forums/topic/quick-way-to-make-a-slider/

If you have GenerateBlocks already, you can just use the Query Loop Block, then just add a script and some CSS to turn it into a Carousel.

Yes, it would be good to place the Query Loop in a container.

Add a couple of buttons in the Container along with the Query Loop, then set them to position: absolute and position them to your preference.

Then, add a script. There might be a carousel that has a good script here: https://codepen.io/tag/carousel?

Many thanks,
