Opera Show Format
The Opera Show Format is a set of conventions used in a web page using XHTML 1.0 Strict and CSS 2.1. It is designed to allow presentations to be easily created with web authoring tools. OSF requires that a number of meta tags be present, including version, generator, author, and presdate. The entire presentation, including all slides and images is contained in a single file. The look of all slides is controlled by the layout section, contained in a
<div class="layout"> HTML element. The slides themselves are contained in a presentation section contained in a <div class="presentation"> element. Each slide is contained in a <div class="slide"> element.
