Start with a blank HTML document and add a <DIV> with ID #slideshow. The entire document will be dedicated to the slideshow. To embed the slideshow into other documents, use the <OBJECT> tag.
Each slide is a <DIV> with the classname "slide". The title slide has the additional class "title". Fill each slide with the content that should be on that slide.
Finally, add a navigation element (such as <P>) to the #slideshow element, and fix it to always appear at the bottom of the screen.
Next step: basic document styling
To ensure the correct aspect ratio for the document, use the CSS padding trick:
Use CSS to stack the slide <DIV>s on top of each other within the #slideshow element.
The following CSS rules will (a) keep the title slide above the stack, and (b) push the selected slide to the very top.
