Build Stunning Websites with Free Accordion Slider UI Component: A GitHub Guide by Roktim Ashraful

Hi, I’m Roktim Ashraful—Let Me Show You Accordion Slider!

As a developer, I’ve always wanted to create a UI component that’s simple to use, lightweight, and adaptable for any project. That’s why I built the AccordionSlider—a free, open-source slider that combines the visual appeal of an accordion with smooth, interactive transitions. Today, I’ll walk you through how it works, how to set it up, and why I designed it to be SEO-friendly. Let’s get started!

Why I Built This Accordion Slider

I’ve seen so many sliders that are either too bulky, rely on heavy libraries, or aren’t optimized for mobile. I wanted to create something different:

• Lightweight: No jQuery or bloat—just vanilla JavaScript.
• Responsive First: It adapts to any screen size automatically.
• Easy to Customize: Change colors, sizes, and animations with minimal effort.
• Free Forever: I believe tools like this should be accessible to everyone.

Whether you’re showcasing products, portfolio work, or blog content, this slider is designed to make your website stand out—without slowing it down.

Key Features I’m Proud Of

1. Smooth Animations
   I used CSS transitions to make panels expand and shrink fluidly. It feels natural, like flipping through a magazine!
2. Mobile-Friendly Design
   On smaller screens, inactive panels shrink to give focus to the active one. No more awkwardly cropped images!
3. Auto-Slide Mode
   Set it to cycle through panels automatically (great for hero banners) or let users navigate manually with Next/Previous buttons.
4. SEO-Ready Structure
   I structured the HTML with semantic tags and clean code so search engines can easily understand your content.

Step 1: Download the Files

Visit my GitHub repository and download the code. If you’re new to GitHub, just click the green “Code” button and download the ZIP file.

Step 2: Add the HTML

Copy this basic structure into your project. Customize the images and text with your content:

<!-- index.html --> 
<div class="accordion-slider">  
  <button class="as-prev">←</button>  
  <div class="as-panels">  
    <!-- The active panel is larger by default -->  
    <div class="as-panel active">  
      <img src="coffee-shop.jpg" alt="Cozy Café in Downtown Seattle">  
      <p class="caption">Visit us for artisan coffee!</p>  
    </div>  
    <div class="as-panel">  
      <img src="pastries.jpg" alt="Freshly Baked Croissants">  
      <p class="caption">Daily fresh pastries</p>  
    </div>  
    <!-- Add more panels here -->  
  </div>  
  <button class="as-next">→</button>  
</div>  

Step 3: Style It Your Way

Here’s the CSS I included. Tweak the colors, sizes, and effects to match your brand:

style.css 

.accordion-slider {  
  max-width: 1200px;  
  margin: 2rem auto;  
}  

.as-panel {  
  width: 100px; /* Collapsed size */  
  opacity: 0.7;  
  transition: all 0.3s ease-in-out;  
}  

.as-panel.active {  
  width: 600px; /* Expanded size */  
  opacity: 1;  
}  

.caption {  
  font-family: 'Arial', sans-serif;  
  color: #ffffff;  
  background: rgba(0, 0, 0, 0.5);  
  padding: 8px;  
}  

Step 4: Activate the Slider

Add this JavaScript snippet to enable auto-sliding and other features:

const slider = new AccordionSlider('.accordion-slider', {  
  autoLoop: true, // Auto-play the slider  
  loopInterval: 4000, // Change slides every 4 seconds  
  pauseOnHover: true, // Pause when users hover  
});  

SEO Tips from My Experience

1. Write Descriptive Alt Text
   Don’t just write “image1.jpg.” Use keywords like “organic coffee beans close-up” to help Google understand your images.
2. Compress Your Images
   Large images slow down your site. Use free tools like Squoosh to shrink file sizes without losing quality.
3. Add Hidden Text (If Needed)
   If your slider is the main content, include a short paragraph below it with keywords like “best coffee shop in Seattle.”
