Accordion gallery | Responsive Gallery using html css javascript

Welcome🎉 to Code With Random blog. In this blog, we learn how we create an Accordion gallery. We use HTML, Css, and javascript for this Accordion gallery. Hope you enjoy our blog so let’s start with a basic HTML structure for an Accordion gallery.

HTML code

 <!DOCTYPE html>  
 <html lang="en">  
  <head>  
   <meta charset="UTF-8" />  
   <meta http-equiv="X-UA-Compatible" content="IE=edge" />  
   <meta name="viewport" content="width=device-width, initial-scale=1.0" />  
   <title>Accordion gallery</title>  
   <link rel="stylesheet" href="style.css" />  
  </head>  
  <body>  
   <div id="bg"></div>  
   <div id="fg"></div>  
   <script src="https://unpkg.co/gsap@3/dist/gsap.min.js"></script>  
   <script src="index.js"></script>  
  </body>  
 </html>

There is all HTML code for the Accordion gallery. Now, you can see output without CSS, then we write css & javascript for the Accordion gallery.
