Yeah to set the block display to none somehow works. But that's not really what I wanted to do.
I have 6 slides at mobile viewport and 2 slides at desktop viewport
wanted to distribute the content of 6 mobile slides into 2 slides at desktop viewport.
The work around for now is to have 4 empty slides at end of desktop viewport and set display none,
But I don't think that's not really practical .
These kind of issue has different solution , and the solution is two have two separate slides and use mobile and desktop redirect method I guess, because yes we can manipulate the CSS at different viewport but there is no way to control HTML elements and content written in HTML document at different viewport.
