pure javascript slide showI have been always fascinated about the slideshows, how do they make one. Well here is the basic slideshow with pure JavaScript. No frameworks are used, No chunks of codes,  Simple Slideshow with 100% pure home grown JavaScript.

Demo Download Code

Lets start with the HTML.


  • div “show ” – this is where the images are displayed [ fixed width/ height, overflow hidden]
  • div “slideHolder” – is the div that holds the slides [relative to "show", images float left]

Here is the CSS


Slide Concept

Use the margin left property to move the slideHolder div inwards show div.  The overflowing part is hidden by the css. A timer function is used to iteratively reduce the margin left , lets call the function as slider(). A function named revert() is used to revert back the margins to its original position.

Animated Twitter Feed widget with Simple JavaScript

Demo Download Code
Here is a quick implementation of Twitter Feed using Simple JavaScript, No frameworks are used. Lets start with the HTML

<div id=”feedWraper”>
<div id=”twitterFeed”></div>
<div id=”feedCache”></div>

  • “feedWraper ” holds the widget , hence its width and height should be fixed.
  • “twitterFeed” contains all the tweets , and its will be animated with simple JavaScript
  • “feedCache” is a hidden div that stores the tweets.


The whole process can be divided into three

  1. JSONP Call
  2. Parsing JSON results [tweets]
  3. Animation

For the JSON call to work properly, all the supporting elements and reference functions should be available before the JSON request. That means all the HTML , CSS and JavaScript for the widget should be on the top and JSON Call should be at the bottom.
