Javascript Slider Carousel

The simplest javascript slider

You can add as many pictures as you like. All of them will appear at a given interval.

HTML


<div id="carousels">
<div class="carousel demonstration"><img src="images/1.jpg"></div>
<div class="carousel"><img src="images/2.jpg"></div>
<div class="carousel"><img src="images/3.jpg"></div>
</div>

Javascript


<script>
var carousels = document.querySelectorAll('#carousels .carousel');
var currentCarousel = 0;
var carouselInterval = setInterval(nextCarousel,5000); /* Interval between pictures */

function nextCarousel(){
carousels[currentCarousel].className = 'carousel';
currentCarousel = (currentCarousel+1)%carousels.length;
carousels[currentCarousel].className = 'carousel demonstration';
}
</script>

CSS


#carousels{
position: relative;
}

.carousel{
position: absolute;
left: 0;
top: 0;
opacity: 0;
transition: opacity 3s; /* Picture appearance time */
}

.demonstration{
opacity: 1;
}

I wish you creative successes.
