Bootstrap 4 - Carousel

A carousel in Bootstrap 4 can be defined as a slideshow that is used for the purpose to slideshow through a series of content to show the audience the content and to enhance the website. A carousel can also be called as slideshow or image slider. It can be regarded as one of the best ways of displaying the large number of contents inside a small space on a web page.

A carousel can be created in four main ways, which are:

  1. Using slides only
  2. Using controls
  3. With the indicators
  4. With the captions

  2. .carousel-control-next class : It inserts a right or next button to the carousel, that will give access to the user to go forward between the slides.
  3. .carousel-control-prev-icon class : It can be used along with the .carousel-control-prev in order to create a previous button.
  4. .carousel-control-next-icon class : It can be used along with the .carousel-control-next to create a "next" button

With the Captions:

A user can also add captions to their slides in Bootstrap 4. A caption can be easily used to convey to the audience of the website that what exactly is happening in the carousel. For the purpose of adding captions, a user has to add elements inside <div class="carousel-caption"> within each <div class="carousel-item"> in order to create a caption for every slide.
