I am attempting to create a R Presentation (.Rpres) using RStudio 0.98.1028 with a different background image on the title slide and another background image on the rest of
You're 99% of the way there. Just one or two more tweaks and you'll have it. You may consider adding the following to ensure your slides are using the separate css file with something like the following added to your title slide.
Intro
======
author: Clever Name
css: css-file.css
You then can overwrite the background of the title slide by including the following between <style> </style> tags at the very top of your .Rpres file before your intro slide, or in your separate css file.
<style>
/* Your other css */
.section .reveal .state-background {
background: url(foo1.png);
background-position: center center;
background-attachment: fixed;
background-repeat: no-repeat;
background-size: 100% 100%;
}
</style>
You're really close. Just change your title-slide { /* do stuff */ } to .section .reveal .state-background { /* do stuff */ }
