VML Example
With just a few lines of code, you can create some pretty interesting effects. Granted, we could have created another JPEG or GIF graphic here, but we think you'll agree that it is simpler and more convenient to create and then play with the few lines of text in the Web page document presented in this lab exercise. 1. Download the file called SPFeature.htm from the Chapter 11 page of this book's Web site as noted in the book's introduction, and put the file in the C WWW SpaceGems directory. 2....
