css - text - effects
You can use CSS filters to add special effects to text, images and other aspects of a webpage without using images or other graphics. Filters only work on Internet Explorer 4.0+,. So if you are developing your site for multi browsers then it may not be a good idea to use CSS filters because there is a possibility that it would not give any advantage.
In this tutorial we will see detail of each CSS filter. These filters may not work in your browser.
