Question

How would you implement a carousel in bootstrap?

Answer 1

Here is an example with a detailed explanation:

<div id="myCarousel" class="carousel slide" data-ride="carousel">
 <!-- Indicators -->
 <ul class="carousel-indicators">
   <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
   <li data-target="#myCarousel" data-slide-to="1"></li>
   <li data-target="#myCarousel" data-slide-to="2"></li>
 </ul>
 <!-- Wrapper -->
 <div class="carousel-inner">
   <div class="carousel-item active">
     <img src="ap.jpg" alt="Apple">
     <div class="carousel-caption">
       <h3>APPLE</h3>
     </div>
   </div>
  
       <div class="carousel-item">
     <img src="or.jpg" alt="Orange">
     <div class="carousel-caption">
       <h3>ORANGE</h3>
     </div>
   </div>
   
   <div class="carousel-item">
      <img src="kw.jpg" alt="Kiwi">
      <div class="carousel-caption">
        <h3>KIWI</h3>
      </div>
    </div>
 </div>

 <!-- Left and Right Controls -->
 <a class="carousel-control-prev" href="#myCarousel" data-slide="prev">
   <span class="carousel-control-prev-icon"></span>
 </a>
 <a class="carousel-control-next" href="#myCarousel" data-slide="next">
   <span class="carousel-control-next-icon"></span>
 </a>
</div>

The outermost <div> is as follows:

• For carousel controls to work properly, they must have an id (in this case, id="myCarousel").
• This <div> has the class="carousel" to indicate that it contains a carousel.
• When a new item is displayed, the .slide class adds a CSS transition and animation effect that causes the objects to slide. If you don't want this effect, leave this class out.
• When the page loads, the data-ride= "carousel" attribute tells Bootstrap to start animating the carousel right away.

The section on "Indicators" is as follows:

• Each slide's indicators are the small dots at the bottom (which indicates how many slides there are in the carousel, and which slide the user is currently viewing).
• With the class .carousel-indications, the indicators are supplied in an ordered list.
• The data-target attribute refers to the carousel's id.
• When a user clicks on a given dot, the data-slide-to attribute defines the slide they should go to.

The "Wrapper" section is as follows:

• A div with the class .carousel-inner specifies the slides.
• Each slide's content is defined by a div with the class .item. This can be in the form of text or visuals.
• One of the slides must have the .active class applied to it. The carousel will not be viewable otherwise.
• To generate a caption for each slide, a <div class="carousel-caption"> is added within each <div class="item">.

The section on "Left and Right Controls" is as follows:

• This code adds "left" and "right" buttons, allowing the user to manually navigate between slides.
• The data-slide attribute takes the keywords "prev" or "next," which change the position of the slide in relation to its current location.
