configuring ioslides background with css

Question

How can I remove the grey gradient at the bottom of slides generated with ioslides using Rstudio markdown? I managed to remove it from the title slide using custom css:

.title-slide {
 background-color: white; 
}

I have not succeeded in removing it from all other slides, however. The ioslides markdown documentation provides very little documentation of the default css used and how to modify it. I have looked at default.css on Github. Is there any other documentation that one can use in customising the appearance of ioslides using css?

I had the same problem. The following css code seems to remove the gradient background:

slides > slide.backdrop {
  background: white;
}
