Fullsreen Image Slideshow In Pure JavaScript – slider-show

slider-show is a responsive, mobile-compatible, fullscreen image slideshow written in pure JavaScript and CSS/CSS3.

It provides an Autoplay control which allows you to play/pause/resume the automatic cross-fading animation.

You can also manually switch between those images by clicking/tapping the pre/next buttons displayed in the bottom control bar.

How to use it:

1. Add images to the slideshow.

<div id="slider">
  <img class="selected" src="1.jpg" alt="Alt 1" />
  <img src="2.jpg" alt="Alt 2" />
  <img src="3.jpg" alt="Alt 3" />
  <img src="4.jpg" alt="Alt 4" />
  <img src="5.jpg" alt="Alt 5" />
</div>

2. Add controls to the slideshow.

<div class="controls">
  <button id="prev">Prev</button>
  <button id="stop">Pause</button>
  <button id="next">Next</button>
</div>

3. The necessary CSS styles for the slideshow & controls.
