In this blog post, we’ll delve into creating a dynamic image slider with navigation controls using HTML, CSS, and JavaScript. This slider allows users to cycle through a series of images with smooth transitions and provides next and previous buttons for navigation.
HTML Structure:
The HTML structure defines the layout and content of the image slider. Here’s a breakdown:
<main>
<ul class='gallery'>

}- Global Styles:
- Resets default browser styles and sets the background color.
- Image Item Styles:
- Defines dimensions, position, background, border radius, and box shadow for each image item.
- Applies transition effects for smoother animations.
- Content Styles:
- Styles the content container with appropriate typography, text shadow, and opacity transitions.
- Adjusts the positioning and appearance of the title, description, and button.
- Navigation Button Styles:
- Positions the navigation buttons at the bottom center of the slider.
- Styles the buttons with background color, border, padding, and hover effects.
JavaScript Functionality:
The JavaScript code adds interactivity to the image slider, enabling navigation between images. Key functionalities include:
const gallery = document.querySelector('.gallery');
function moveSlide(e) {
const slides = document.querySelectorAll('.slide');
e.target.matches('.next') && gallery.append(slides[0])
e.target.matches('.prev') && gallery.prepend(slides[slides.length-1]);
}
document.addEventListener('click',moveSlide,false);- Navigation Activation:
- Listens for click events on the navigation buttons.
- Moves the first or last image item to the end or beginning of the slider, respectively, based on the clicked button.
Conclusion:
In this blog post, we’ve explored the creation of a dynamic image slider with navigation controls using HTML, CSS, and JavaScript. By understanding the structure, styling, and functionality of each component, you can customize and enhance the slider to suit various content and design requirements. Whether you’re showcasing a portfolio, product gallery, or storytelling visuals, this slider offers a user-friendly and engaging way to present images on your website.
