Responsive Background Image Slideshow With Fade Transitions

Description:

A fully responsive background image slideshow with CSS3 powered fade transitions and next/prev/autoplay/pause controls.

Written in Vanilla JavaScript and CSS transitions.

How to use it:

1. Add as many slides to the slideshow.

<ul id="all_slides">
  <li class="slide active"></li>
  <li class="slide"></li>
  <li class="slide"></li>
  ...
</ul>

2. Add controls (next, previous, play/pause) to the slideshow. In this example, we’re going to use Font Awesome iconic font for the control icons.

<div class="buttons">
  <button class="controls" id="previous"><i class="far fa-arrow-alt-circle-left"></i></button>
  <button class="controls" id="pause"><i class="far fa-pause-circle"></i></button>
  <button class="controls" id="next"><i class="far fa-arrow-alt-circle-right"></i></button>
</div>

3. The core CSS styles for the slideshow.

#all_slides{
  position: relative;
  height: 100vh;
  padding: 0px;
  margin: 0px;
  list-style-type: none;
}

.slide{
  position: absolute;
  left: 0px;
  top: 0px;
  width: 100%;
  height: 100%;
  opacity: 0;
  z-index: 1;
  -webkit-transition: opacity 1s;
  -moz-transition: opacity 1s;
  -o-transition: opacity 1s;
  transition: opacity 1s;
}

.active{
  opacity: 1;
  z-index: 2;
}

.slide{
  font-size: 40px;
  padding: 40px;
  box-sizing: border-box;
  background: #333;
  color: #fff;
  background-size: cover;
}

4. Add background images to the slides.

.slide:nth-of-type(1){
  background-image: url('1.jpg');
  background-size: cover;
  background-position: 50% 50%;
  background-repeat: no-repeat;
}

.slide:nth-of-type(2){
  background-image: url('2.jpg');
  background-size: cover;
  background-position: 50% 50%;
  background-repeat: no-repeat
}

.slide:nth-of-type(3){
  background-image: url('3.jpg');
  background-size: cover;
  background-position: 50% 50%;
  background-repeat: no-repeat
}

5. The CSS rules for the controls.

.controls{
  display: none;
}

.controls{
  display: inline-block;
  position: relative;
  top: 1rem;
  right: .5rem;
  border: none;
  outline: none;
  font-size: 20px;
  cursor: pointer;
  border: 2px solid #fff;
  border-radius: 1.5rem;
  background: gold;
  width: 3rem;
  height: 3rem;
  margin-left: .5rem;
}

.controls:hover,
.controls:focus{
  background: #eee;
  color: #333;
}

.container{
  position: relative;
}

.buttons{
  position: absolute;
  right: .5rem;
  top: 0px;
  z-index: 10;
  font-size: 0px;
}

6. Load the main script at the end of the document. Done.

<script src="static/js/main.js"></script>
