Creating an image slider in WordPress can greatly enhance your website’s visual appeal and user engagement. While plugins offer an easy solution, you can also build a slider manually using HTML, CSS, and a bit of JavaScript. This approach gives you more control over the design and functionality of your slider. In this article, we’ll walk you through the steps to create an image slider in WordPress without relying on plugins.

Why Create a Slider Without a Plugin?

Opting to create an image slider manually has several benefits:

1. Full Control: Custom code allows you to tailor the slider’s design and functionality to your exact needs.
2. Reduced Plugin Overhead: Fewer plugins mean less bloat, which can lead to faster load times and improved site performance.
3. Learning Opportunity: Coding your slider helps you learn more about HTML, CSS, and JavaScript, which can be valuable for other projects.

Steps to Create an Image Slider in WordPress Without a Plugin

1. Prepare Your Images

Before you start coding, gather and prepare the images you want to include in your slider:

• Optimize Images: Ensure your images are web-optimized for faster loading. Tools like TinyPNG or Adobe Photoshop can help with this.
• Upload Images: Upload your images to the WordPress Media Library.

2. Add HTML Structure

You’ll need to insert HTML into a WordPress page or post. You can do this using the Block Editor or the Classic Editor. Here’s a basic HTML structure for a slider:

1. Go to Pages or Posts and edit the page or post where you want the slider.
2. Switch to the Code Editor (Classic Editor) or add a Custom HTML block (Block Editor).
3. Insert the following HTML code:

   <div class="slider">
     <div class="slides">
       <div class="slide"><img src="URL_TO_IMAGE1" alt="Image 1"></div>
       <div class="slide"><img src="URL_TO_IMAGE2" alt="Image 2"></div>
       <div class="slide"><img src="URL_TO_IMAGE3" alt="Image 3"></div>
     </div>
     <a class="prev" onclick="plusSlides(-1)">❮</a>
     <a class="next" onclick="plusSlides(1)">❯</a>
   </div>

Replace URL_TO_IMAGE1, URL_TO_IMAGE2, etc., with the actual URLs of your images.

3. Add CSS Styling

To make your slider visually appealing and functional, add some CSS. Go to Appearance > Customize > Additional CSS and add the following code:

   .slider {
     position: relative;
     max-width: 100%;
     margin: auto;
     overflow: hidden;
   }
   .slides {
     display: flex;
     transition: transform 0.5s ease-in-out;
   }
   .slide {
     min-width: 100%;
     box-sizing: border-box;
   }
   .slide img {
     width: 100%;
     vertical-align: middle;
   }
   .prev, .next {
     cursor: pointer;
     position: absolute;
     top: 50%;
     width: auto;
     padding: 16px;
     margin-top: -22px;
     color: white;
     font-weight: bold;
     font-size: 18px;
     transition: 0.6s ease;
     border-radius: 0 3px 3px 0;
     user-select: none;
     background-color: rgba(0,0,0,0.5);
   }
   .next {
     right: 0;
     border-radius: 3px 0 0 3px;
   }
   .prev:hover, .next:hover {
     background-color: rgba(0,0,0,0.8);
   }

4. Add JavaScript for Functionality

To make the slider functional, you need to add JavaScript for slide navigation. You can do this by adding the following script to the same Custom HTML block or using a Custom Code block if available:

   <script>
     let slideIndex = 1;
     showSlides(slideIndex);

     function plusSlides(n) {
       showSlides(slideIndex += n);
     }

     function showSlides(n) {
       let slides = document.getElementsByClassName("slide");
       if (n > slides.length) {slideIndex = 1}
       if (n < 1) {slideIndex = slides.length}
       for (let i = 0; i < slides.length; i++) {
         slides[i].style.display = "none";
       }
       slides[slideIndex-1].style.display = "block";
     }
   </script>

5. Test Your Slider

Finally, preview your page to ensure the slider works as expected. Test the slider on different devices and screen sizes to make sure it’s responsive and functional.
