OperaShow is a great way to create and view clean, elegant presentation slides. It takes a bit of work to create your first OperaShow presentation. But once you have your stylesheet and slide template in place, subsequent OperaShow presentations will be easy to put together. While the presentation used as an example in this article is visually very simple, yours don't have to be. With a bit of creativity and some clever use of HTML and CSS, you can create stunning OperaShow slides that have as much impact as those created using PowerPoint or any other presentation tool.
