<!-- close: meta paragraph -->

jQuery can pretty much do anything you can think of. All you need is a creative imagination and some time to learn the simple and intuitive API .

 

In this article, we share with you some innovative uses of jQuery in animating web design elements. You’ll read about some interesting techniques, tutorials, and examples that will show you how to create similar effects on your own websites and web apps.

 

1. Puffing Smoke Effect in jQuery

 

 

This example by Dutch web developer Gaya Kessler features an impressive animation effect of cartoonish smoke emanating from factory smoke stacks. Kessler thoughtfully supplies a configurable jQuery plugin with instructions based on his site’s header, so that you may create a similar animation effect for your website.

2. Crafting an Animated Postcard

 

 

Sam Dunn of the web development duo, Build Internet, wrote a tutorial on how to create an animated landscape using transparent PNG images. The tutorial takes advantage of the popular jQuery Easing plugin to help with the animation and the setTimeout() JavaScript function to time the events accordingly.

3. Create a Realistic Hover Effect

 

 

In this tutorial, you will learn how to animate image elements in a smooth and fluid manner. The tutorial features objects that, when hovered on, rises upwards. In the live demo of the effect, notice how the reflections and shadows at the bottom also changes when the object lifts up; hence "realistic" in the name of the technique.

4. Scrolling Background Effect

 

 

The creators of the site youlove.us shares their code (and explanation) for making a seamless vertical scrolling CSS background; featured on the site’s header. The script is also dependent on the user’s system time; the animation starts at a different position depending on whether you visit the site at night or in the morning, a nice touch.

6. jQuery Blend

 

 

jQuery Blend is a plugin for animating CSS background images.

8. Stunning Sliding Door Effect

9. Make Your Header Responses to Mouse Movements

 

 

In this jQuery animation technique, you will learn how to animate a set of images that reacts to the user’s mouse movements. When the user hovers over a set of images, the set begins to follow the mouse cursor. This technique can be adapted to many user interface related functions, or you can just use it to impart a memorable experience to your users.

10. Animated Header Using jQuery

 

 

This animated tutorial goes over a similar concept to the youlove.us example of vertically moving a large CSS background image. Illustrations on how the technique works will help readers grok the concept more fully. Devirtuoso, the author of the tutorial, goes through due diligence by offering an IE6 hack for backwards compatibility.
