Slide show using Javascript

javascript

To create a slide show using JavaScript, you can use a combination of HTML, CSS, and JavaScript. Here’s a basic example:

HTML:

<div class="slideshow">
  <img src="slide1.jpg">
  <img src="slide2.jpg">
  <img src="slide3.jpg">
</div>

CSS:

.slideshow {
  position: relative;
  height: 400px;
  overflow: hidden;
}

.slideshow img {
  position: absolute;
  top: 0;
  left: 0;
  opacity: 0;
  transition: opacity 1s ease-in-out;
}

.slideshow img.active {
  opacity: 1;
}

JavaScript:

var slides = document.querySelectorAll('.slideshow img');
var currentSlide = 0;
var slideInterval = setInterval(nextSlide, 3000);

function nextSlide() {
  // Set the current slide to inactive
  slides[currentSlide].className = '';
  // Increment the current slide index
  currentSlide = (currentSlide + 1) % slides.length;
  // Set the next slide to active
  slides[currentSlide].className = 'active';
}

In this example, we have a simple HTML structure with a

containing multiple elements. The CSS sets the position of the images to be absolute, which allows them to be layered on top of each other, and uses the opacity property and CSS transitions to fade between slides. The JavaScript sets up an interval that calls a function to transition between slides.

The slides variable selects all the elements in the slideshow, and the currentSlide variable keeps track of the index of the currently displayed slide. The slideInterval variable sets up a timer to call the nextSlide function every 3 seconds.

The nextSlide function sets the current slide to inactive by removing the active class, increments the currentSlide index, and sets the next slide to active by adding the active class. The modulo operator is used to wrap the index around to the beginning when we reach the end of the slideshow.

This is a basic example that can be expanded upon to add more features, such as adding navigation buttons, changing the slide transition effect, or adding captions.
