Create CSS based Simple Slider

Simplest Slideshow

Download Source Code: Click Here to download

One of my Colleague was looking at doing a simple slideshow. The requirements were very straight forward like Images should MOVE sequentially after some Interval . I put my thinking cap on and decided to write a script from scratch. In the end, it turned out much simpler than even I predicted.Here you see how it looks like

You can customize it as per your requirement ..

HTML

Wrapper with div's as the "slides", which can contain any content.

 <div style="width: 500px; height: 300px;" id="simpleslider">
  <a href="#" class="control_next">>></a>
  <a href="#" class="control_prev"><</a>
  <ul style="width: 2000px; margin-left: -500px; left: 0px;">
   <li><img alt="" src="1.jpg"/></li>
  <li><img alt="" src="2.jpg"/></li>
   <li><img alt="" src="1.jpg"/></li>
    <li><img alt="" src="3.jpg"/></li>
 
  <li><img alt="" src="4.jpg"/></li>
 
   </ul>  
</div>
 

CSS

Slides need to be absolutely positioned within the wrapper.
#simpleslider {
  position: relative;
  overflow: hidden;
  margin: 20px auto 0 auto;
  border-radius: 4px;
}

#simpleslider ul {
  position: relative;
  margin: 0;
  padding: 0;
  height: 200px;
  list-style: none;
}

#simpleslider ul li {
  position: relative;
  display: block;
  float: left;
  margin: 0;
  padding: 0;
  width: 500px;
  height: 300px;
  background: #ccc;
  text-align: center;
  line-height: 300px;
}

a.control_prev, a.control_next {
  position: absolute;
  top: 40%;
  z-index: 999;
  display: block;
  padding: 4% 3%;
  width: auto;
  height: auto;
  background: #2a2a2a;
  color: #fff;
  text-decoration: none;
  font-weight: 400;
  font-size: 18px;
  opacity: .4;
  cursor: pointer;  
}

a.control_prev:hover, a.control_next:hover {
  opacity: 1;
  -webkit-transition: all 0.2s ease;
}

a.control_prev {
  border-radius: 0 2px 2px 0;
}

a.control_next {
  right: 0;
  border-radius: 2px 0 0 2px;
}

.slider_option {
  position: relative;
  margin: 10px auto;
  width: 160px;
  font-size: 18px;
}

JQuery

<script type="text/javascript">
 
 jQuery(document).ready(function ($) {

  $('#body').text(function(){
    setInterval(function () {
        moveAhead();
    }, 2000);
  });
  
 var total_Slides= $('#simpleslider ul li').length;
 var width_Slide = $('#simpleslider ul li').width();
 var hight_Slide = $('#simpleslider ul li').height();
 var sliderUlWidth = total_Slides* width_Slide;
 
 $('#simpleslider').css({ width: width_Slide, height: hight_Slide });
 
 $('#simpleslider ul').css({ width: sliderUlWidth, marginLeft: - width_Slide });
 
    $('#simpleslider ul li:last-child').prependTo('#simpleslider ul');

    function moveBack() {
        $('#simpleslider ul').animate({
            left: + width_Slide
        }, 200, function () {
            $('#simpleslider ul li:last-child').prependTo('#simpleslider ul');
            $('#simpleslider ul').css('left', '');
        });
    };

    function moveAhead() {
        $('#simpleslider ul').animate({
            left: - width_Slide
        }, 200, function () {
            $('#simpleslider ul li:first-child').appendTo('#simpleslider ul');
            $('#simpleslider ul').css('left', '');
        });
    };

    $('a.control_prev').click(function () {
        moveLeft();
    });

    $('a.control_next').click(function () {
        moveRight();
    });

});    
 
 </script>
