Default Post Type Slider
Below is an example of the default Post Types Slider layout without any modifications to the element. As you can see it displays a caption over the image with a dark background.
Caption Under The Image
You can choose to display your captions below the image like in the example below. This way the image is not covered up at all. You could also disable the caption completely if you prefer.
Post Cards Carousel
Instead of using the Post Types Slider element, we recommend using the newer Post Cards element set to the carousel display type. By using the Post Cards element you will have access to tons of pre-built entry styles or you can create your own using WPBakery, Elementor or Gutenberg.
Post Cards Single Slide Carousel
The Post Cards carousel display type has many settings you can use to customize the carousel display. For example you can choose a different arrow style as well as alter the number of cards that display at a time.
