Create a Slideshow Image Gallery Using HTML5

Introduction

 
This is a simple application for beginners that shows how to create a slideshow image gallery using HTML 5, JQuery and CSS tools. We know that HTML 5 is the advanced version of HTML. Basically HTML 5 can be used to develop 3D applications. This article is intended to help with the use of HTML5 tools to develop slideshow image gallery applications. CSS is the acronym for Cascading Style Sheet that is used for design. CSS defines how HTML elements are to be displayed. Canvas is an important tag of an HTML 5 that is used to show the image and text in an HTML 5 application. I hope this article helps to develop a slideshow image gallery using HTML 5, JQuery and CSS tools.

Step 7:Now in this step we define a CSS file named Photo1.css. In CSS we define all properties of sliders; that is background, border, margin, height, width, position, display, etc. 
 
Code
  1. body  
  2.    {  
  3.        color:Green;  
  4.        background:url('img/bg.jpg'repeat-x #CC99FF;  
  5.        font:13px "Lucida Sans Unicode",Arial;  
  6.       }  
  7.  #SLIDE  
  8.     {  
  9.        background-color:#F5F5F5;  
  10.        border:1px solid #FFFFFF;  
  11.        height:340px;  
  12.        margin:150px auto 0;  
  13.        position:relative;  
  14.        width:640px;  
  15.        -moz-box-shadow:0 0 22px #111;  
  16.        -webkit-box-shadow:0 0 22px #111;  
  17.        box-shadow:0 0 22px #111;  
  18.         }  
  19.  #SLIDE ul  
  20.     {  
  21.        height:320px;  
  22.        left:10px;  
  23.        list-style:none outside none;  
  24.        overflow:hidden;  
  25.        position:absolute;  
  26.        top:10px;  
  27.        width:620px;  
  28.      }  
  29.   #SLIDE li  
  30.     {  
  31.        position:absolute;  
  32.        display:none;  
  33.        z-index:10;  
  34.        }  
  35.   #SLIDE li:first-child  
  36.     {  
  37.        display:block;  
  38.        z-index:1000;  
  39.      }  
  40.   #SLIDE .slideActive  
  41.    {  
  42.        z-index:1000;  
  43.        }  
  44.   #SLIDE canvas{  
  45.        display:none;  
  46.        position:absolute;  
  47.        z-index:100;  
  48.      }  
  49.   #SLIDE .arrow  
  50.    {  
  51.        height:86px;  
  52.        width:60px;  
  53.        position:absolute;  
  54.        top:50%;  
  55.        margin-top:-43px;  
  56.        cursor:pointer;  
  57.        z-index:5000;  
  58.      }  
  59.   #SLIDE .previous{ background-position:left top;left:0;}  
  60.   #SLIDE .previous:hover{ background-position:left bottom;}  
  61.   #SLIDE .next{ background-position:right top;right:0;}  
  62.   #SLIDE .next:hover{ background-position:right bottom;} 
Step 8: Now in this step we set a path of a image in a div.
 
Code
  1. <div id="slideshow">  
  2.     <ul class="slides">  
  3.     <li><img src="Gallery/2aaaaaaa.jpg" width="620" height="320" alt="Marsa Alam underawter close up" /></li>  
  4.     <li><img src="Gallery/143392-30741-19_10_13---Spring_web.jpg" width="620" height="320" alt="Marsa Alam underawter close up" /></li>  
  5.     <li><img src="Gallery/c-sharpcorner.com.jpg" width="620" height="320" alt="Marsa Alam underawter close up" /></li>  
  6.     <li><img src="Gallery/1.jpg" width="620" height="320" alt="Marsa Alam underawter close up" /></li>  
  7.     <li><img src="Gallery/2.jpg" width="620" height="320" alt="Turrimetta Beach - Dawn" /></li>  
  8.     <li><img src="Gallery/3.jpg" width="620" height="320" alt="Power Station" /></li>  
  9.     <li><img src="Gallery/4.jpg" width="620" height="320" alt="Colors of Nature" /></li>  
  10.     </ul>  
  11.     <span class="arrow previous"></span>  
  12.     <span class="arrow next"></span>  
  13. </div> 
image.gif
 
Step 9: Now we have used a js file named galary.js. In the js file, we set a sliding functionality.
 
Code
  1. function createcanOverlay(image) {  
  2.    var can = document.createElement('can'),  
  3.        canContext = can.getContext("2d");  
  4.        can.width = slideshow.width;  
  5.        can.height = slideshow.height;  
  6.        canContext.drawImage(image, 0, 0);  
  7.        var Img = canContext.getImg(0, 0, can.width, can.height),  
  8.        data = Img.data;  
  9.        for (var i = 0, z = data.length; i < z; i++) {  
  10.        data[i] = ((data[i] < 128) ? (2 * data[i] * data[i] / 255) : (255 - 2 * (255 - data[i]) * (255 - data[i]) / 255));  
  11.        data[++i] = ((data[i] < 128) ? (2 * data[i] * data[i] / 255) : (255 - 2 * (255 - data[i]) * (255 - data[i]) / 255));  
  12.        data[++i] = ((data[i] < 128) ? (2 * data[i] * data[i] / 255) : (255 - 2 * (255 - data[i]) * (255 - data[i]) / 255));  
  13.        ++i;  
  14.            }  
  15.        canContext.putImg(Img, 0, 0);  
  16.        image.parentNode.insertBefore(can, image);  
  17.     }  
  18. }); 
Step 10: The complete code of the application is given below.
 
Code
  1. <html>  
  2.   <head>  
  3.   <title>Image Slider Demo</title>  
  4.   <link rel="stylesheet" type="text/css" href="photo1.css" />  
  5.   <body>  
  6.   </head>  
  7.   <div id="slideshow">  
  8.     <ul class="slides">  
  9.     <li><img src="Gallery/2aaaaaaa.jpg" width="620" height="320" alt="Marsa Alam underawter close up" /></li>  
  10.     <li><img src="Gallery/143392-30741-19_10_13---Spring_web.jpg" width="620" height="320" alt="Marsa Alam underawter close up"    /></li>  
  11.     <li><img src="Gallery/c-sharpcorner.com.jpg" width="620" height="320" alt="Marsa Alam underawter close up" /></li>  
  12.     <li><img src="Gallery/1.jpg" width="620" height="320" alt="Marsa Alam underawter close up" /></li>  
  13.     <li><img src="Gallery/2.jpg" width="620" height="320" alt="Turrimetta Beach - Dawn" /></li>  
  14.     <li><img src="Gallery/3.jpg" width="620" height="320" alt="Power Station" /></li>  
  15.     <li><img src="Gallery/4.jpg" width="620" height="320" alt="Colors of Nature" /></li>  
  16.     </ul>  
  17.     <span class="arrow previous"></span>  
  18.     <span class="arrow next"></span>  
  19.   </div>  
  20.   <script src="Scripts/galary.js"></script>  
  21.   <h1>Tom Develop a Slider image</h1>   
  22.   </body>  
  23. </html>
