Adding an image slider to your WordPress site can greatly enhance its visual appeal and functionality. While many users rely on plugins to create sliders, it’s possible to add an image slider without using any additional plugins. In this guide, we’ll walk you through the steps how to add image slider in wordpress without plugin and a bit of custom code.

Why Use an Image Slider?

An image slider is a great way to showcase multiple images in a single space, making your website more engaging and dynamic. Sliders are particularly useful for displaying portfolios, testimonials, or promotional content. They help in catching the visitor’s attention and can improve user interaction on your site.

Steps to Add an Image Slider in WordPress Without a Plugin

Step 1: Prepare Your Images

1. Select and Resize Images: Choose the images you want to include in your slider. Make sure they are properly sized for your website to ensure fast loading times. You can use tools like Photoshop or online image editors to resize your images.
2. Upload Images to WordPress Media Library: Go to your WordPress dashboard, navigate to “Media,” and then “Add New.” Upload all the images you want to use in your slider.

Step 2: Add Custom HTML and CSS

1. Create a New Page or Post: Navigate to “Pages” or “Posts” in your WordPress dashboard and click “Add New.”
2. Switch to HTML View: In the editor, switch to the HTML view by clicking on the “Code Editor” or “Text” tab.
3. Add HTML Code for Slider: Insert the following HTML code into the editor. This code will create the basic structure of your slider.

   <div class="custom-slider">
       <div class="slides">
           <div class="slide"><img src="IMAGE_URL_1" alt="Slide 1"></div>
           <div class="slide"><img src="IMAGE_URL_2" alt="Slide 2"></div>
           <div class="slide"><img src="IMAGE_URL_3" alt="Slide 3"></div>
           <!-- Add more slides as needed -->
       </div>
   </div>

Replace IMAGE_URL_1, IMAGE_URL_2, etc., with the URLs of the images you uploaded to the Media Library.

4. Add CSS for Styling: To style your slider, switch back to the visual editor or the “Additional CSS” section in the WordPress Customizer. Add the following CSS code:

   .custom-slider {
       position: relative;
       width: 100%;
       overflow: hidden;
   }

   .slides {
       display: flex;
       transition: transform 0.5s ease-in-out;
   }

   .slide {
       min-width: 100%;
       box-sizing: border-box;
   }

   .slide img {
       width: 100%;
       height: auto;
   }

   /* Optional: Add navigation styles */
   .custom-slider .prev, .custom-slider .next {
       position: absolute;
       top: 50%;
       transform: translateY(-50%);
       background-color: rgba(0,0,0,0.5);
       color: #fff;
       border: none;
       padding: 10px;
       cursor: pointer;
   }

   .custom-slider .prev {
       left: 10px;
   }

   .custom-slider .next {
       right: 10px;
   }

This CSS code will ensure that your slider looks clean and professional. You can adjust the styles as needed to match your website’s design.

Step 3: Add JavaScript for Functionality

1. Include JavaScript for Sliding: To make the slider functional, you need to add some JavaScript. You can add this code in the “Additional JavaScript” section of your theme or use a plugin like “Code Snippets” to add custom scripts.

   let index = 0;
   const slides = document.querySelectorAll('.slide');
   const totalSlides = slides.length;

   function showSlide(n) {
       if (n >= totalSlides) index = 0;
       if (n < 0) index = totalSlides - 1;
       slides.forEach((slide, i) => {
           slide.style.transform = `translateX(-${index * 100}%)`;
       });
   }

   document.querySelector('.prev').addEventListener('click', () => {
       showSlide(index - 1);
   });

   document.querySelector('.next').addEventListener('click', () => {
       showSlide(index + 1);
   });

   setInterval(() => {
       showSlide(index + 1);
   }, 5000); // Change slide every 5 seconds

This JavaScript code will handle the automatic sliding and navigation functionality.

Step 4: Publish Your Slider

1. Preview Your Page or Post: Before publishing, preview your page to make sure the slider looks and works as expected.
2. Publish: Once you’re satisfied with the result, click “Publish” to make your page or post live with the new image slider.

By using a combination of HTML, CSS, and JavaScript, you can create a functional and visually appealing slider that enhances the user experience on your site.
