Building a Dynamic Banner with CSS Sprites - Listing the complete source code for the banner
(Page 4 of 4 )
In consonance with the concepts that I deployed in the section that you just read, below I listed the complete source code that corresponds to this sample banner, which uses a two-image CSS sprite to do its business. Have a look at it, please:

<title>Sample Banner using CSS Sprites</title>
<style type="text/css">

If you don't feel inclined to copy and paste the code of the above example, you can download this ZIP file containing all the supporting material, including the background image that you saw previously. I hope you have a good time testing this CSS sprite-based banner!
Final thoughts
Over the course of this second article of the series, I demonstrated how to create a simple yet effective banner which uses the concept of CSS sprites to work properly, without any noticeable lags between its different stages. As you saw, the logic applied here is identical to that used to build the rollover buttons covered in the first part.
However, this journey hasn't finished yet. In the last tutorial I'm going to teach you how to build a basic image gallery that takes advantage of the functionality provided by CSS sprites to display thumbnails and large pictures as well. See you there!
