Step 1
Create a folder named “images” in the project path and put all the images required for the slider. Make sure that all the images are in the same size (width*height). Otherwise, the slider will misbehave while navigating between slides.
 
Step 2
Add the below code in body section of the HTML page.
 
  1. <body>  
  2.     <div class=“slidercontainer”>  
  3.         <div class=“showSlide fade”>  
  4.             <img src=“images/img1.jpg” />  
  5.             <div class=“content”>Lorem ipsum dolor sit amet</div>  
  6.         </div>  
  7.         <div class=“showSlide fade”>  
  8.             <img src=“images/img2.jpg”/>  
  9.             <div class=“content”>Lorem ipsum dolor sit amet</div>  
  10.         </div>  
  11.   
  12.         <div class=“showSlide fade”>  
  13.             <img src=“images/img3.jpg”/>  
  14.             <div class=“content”>Lorem ipsum dolor sit amet</div>  
  15.         </div>  
  16.         <div class=“showSlide fade”>  
  17.             <img src=“images/img4.jpg”/>  
  18.             <div class=“content”>Lorem ipsum dolor sit amet</div>  
  19.         </div>  
  20.         <!– Navigation arrows –>  
  21.         <a class=“left” onclick=“nextSlide(-1)”>❮</a>  
  22.         <a class=“right” onclick=“nextSlide(1)”>❯</a>  
  23.     </div>  
  24. </body>   
Here, <div class=”slidercontainer”> is the main container for slider and <div class=”showSlide fade”> are the slider images section that are repeating.
 
Step 3
Write the JavaScript code. Considering  it a small example, I am writing the code in the same HTML page using <script type=”text/javascript”></script>.
 
If required, you can create an external JS file in the project path and refer it to the HTML page. 
 
  1. <script type=“text/javascript”>  
  2.         var slide_index = 1;  
  3.         displaySlides(slide_index);  
  4.         function nextSlide(n) {  
  5.             displaySlides(slide_index += n);  
  6.         }  
  7.         function currentSlide(n) {  
  8.             displaySlides(slide_index = n);  
  9.         }  
  10.         function displaySlides(n) {  
  11.             var i;  
  12.             var slides = document.getElementsByClassName(“showSlide”);  
  13.             if (n > slides.length) { slide_index = 1 }  
  14.             if (n < 1) { slide_index = slides.length }  
  15.             for (i = 0; i < slides.length; i++) {  
  16.                 slides[i].style.display = “none”;  
  17.             }  
  18.             slides[slide_index – 1].style.display = “block”;  
  19.         }  
  20. </script>   
All the above functions are user defined. We just only write some logic to read the slides and showing.
 
Step 4
Now, it’s time to apply CSS to showcase the images in a proper position with some styles. Below is the final code —
 
HTML+JavaScript+CSS, 
 
  1. <!DOCTYPE html>  
  2. <html>  
  3. <head>  
  4.     <meta charset=“utf-8” />  
  5.     <title>My Slider</title>  
  6.     <style type=“text/css”>  
  7.         body {  
  8.             margin: 0;  
  9.             background: #e6e6e6;  
  10.         }  
  11.         .showSlide {  
  12.             display: none  
  13.         }  
  14.             .showSlide img {  
  15.                 width: 100%;  
  16.             }  
  17.         .slidercontainer {  
  18.             max-width: 1000px;  
  19.             position: relative;  
  20.             margin: auto;  
  21.         }  
  22.         .left, .right {  
  23.             cursor: pointer;  
  24.             position: absolute;  
  25.             top: 50%;  
  26.             width: auto;  
  27.             padding: 16px;

  33.             border-radius: 0 3px 3px 0;  
  34.         }  
  35.         .right {  
  36.             right: 0;  
  37.             border-radius: 3px 0 0 3px;  
  38.         }  
  39.             .left:hover, .right:hover {  
  40.                 background-color: rgba(115, 115, 115, 0.8);  
  41.             }  
  42.         .content {  
  43.             color: #eff5d4;  
  44.             font-size: 30px;  
  45.             padding: 8px 12px;  
  46.             position: absolute;  
  47.             top: 10px;  
  48.             width: 100%;  
  49.             text-align: center;  
  50.         }  
  51.         .active {  
  52.             background-color: #717171;  
  53.         }  
  54.         /* Fading animation */
