| ## Carousel
 | |
| 
 | |
| Carousel is a slideshow component for cycling through elements like images or slides of text.
 | |
| It provides a dynamic way of representing large amount of data (text or images) by sliding or cycling through, in a smooth fashion
 | |
| 
 | |
| Sample Code of Image Slider is below :
 | |
| 
 | |
| ```html
 | |
| <html>
 | |
| <head>
 | |
|   
 | |
| <!-- BootStrap's minified CSS version -->
 | |
| <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" integrity="sha384-PsH8R72JQ3SOdhVi3uxftmaW6Vc51MKb0q5P2rRUpPvrszuE4W1povHYgTpBfshb" crossorigin="anonymous">
 | |
| 
 | |
| 
 | |
|  </head>
 | |
| 
 | |
| <style>
 | |
|   
 | |
| .carousel-indicators li
 | |
| {
 | |
| background-color:red;
 | |
| } 
 | |
| 
 | |
| .carousel-indicators .active
 | |
| {
 | |
| background-color:blue;
 | |
| }
 | |
| 
 | |
| .carousel-indicators .item
 | |
| {
 | |
| height:700 px;
 | |
| width :800 px;
 | |
| }
 | |
| </style>
 | |
| 
 | |
|

| Understanding the Attributes and classes used in above example :
 | |
| 
 | |
| ### 1) Attributes
 | |
| 
 | |
| a) `data-ride`  :-  `data-ride ="carousel"`  allows on page load animation to begin.
 | |
| 
 | |
| b) `data-target` :- It points to the id of the Carousel
 | |
| 
 | |
| c) `data-slide-to` :- It specifies which slide to move on to when clicking on the indicators(specific dots).
 | |
| 
 | |
| ### 2) Classes
 | |
| 
 | |
| a) `carousel`  :- `class="carousel"` specifies that the  div contains carousel.
 | |
| 
 | |
| b) `slide` :- This class adds CSS transitions.
 | |
| 
 | |
| c) `carousel-inner` :- This denotes the section of code which will hold the text/image to be displayed in slides.
 | |
| 
 | |
| d) `item` :- It refers to the content to be displayed in the carousel.
 | |
| 
 | |
| e) `left carousal-control` :- This adds the back button allowing sliding to the previous slide.
 | |
| 
 | |
| f) `right carousal-control` :- This adds the next button allowing sliding to the next slide.
 | |

 | |
| 
 | |
| ### Usage
 | |
| #### 1) Via data attributes
 | |
| The `data-ride="carousel"` attribute is used to mark a carousel as animating starting at page load.
 | |
| `data-slide` accepts the keywords `prev` or `next`, which alters the slide position relative to its current position. 
 | |
| #### 2) Via JavaScript
 | |
| Call carousel manually with:
 | |
| 
 | |
| `$('.carousel').carousel()`
 | |
| 
 | |
| ### Options
 | |
| Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-interval=""`.
 | |
| 
 | |
| Some frequently used options are:
 | |
| 
 | |
| * interval
 | |
| * pause
 | |
| * ride
 | |
| * wrap
