Caption on Slide

Hello. I want to know if is it possible using caption with slide shortcode. I’m trying using [caption] from default wordpress but I guess it is only for images because it doesn’t work.

Then I try typing it manually but then it always got this big gap like paragraph break. Link related. OFC I could use “title on” and use title as caption. But with that in mobile device, the sentence will covering almost half of the image. Even if I activated lightbox, not every visitor is smart enough or aware that the picture is click-able to show the whole image.

That is why I really need caption that placed below slide. Sometimes the sentences is two line. If I use title on, it looks ugly in mobile device.
