Is there a way to make ordered list items appear faster in incremental mode in Rmarkdown ioslides?

Question

I am using Rmarkdown ioslides. I do not like how slow bullet points appear in the incremental mode. Is there a way to speed them up?

I am looking for something similar Slidy presentations. In slidy bullet points appear instantaneously when you click on the mouse. Thanks in advance

That's one of the transition properties of the CSS. Create a file called delays.css, and put this into it:

.build > * {
-webkit-transition: opacity 0.5s ease-in-out;
-webkit-transition-delay: 0.2s;
-moz-transition: opacity 0.5s ease-in-out 0.2s;
-o-transition: opacity 0.5s ease-in-out 0.2s;
transition: opacity 0.5s ease-in-out 0.2s;
}

Those are the default values. Change the numbers to make things faster or slower. For example, changing all the numbers to 0.0s will make things instant. There are other possible values for ease-in-out, but with no transition time they won't make any difference. If you want to read about them, look here: https://developer.mozilla.org/en-US/docs/Web/CSS/transition .

To make your slides use it, add this to your YAML:

output: 
  ioslides_presentation:
    incremental: true
    css:  delays.css
