Sticky slider with Storefront

I have solved the problem with z-index 9999.

Great to know you solved it. Nice work. ??

Hello Maeve, the plugin has been well integrated. On the smartphone, however, I have slight overlays. That does not look so good.
I want to make the buttons transparent. The answer to threat: Semi transparent buttons I read:
div {div
background: rgba (0,0,0,0.5);
}
In the plugin folder Asset I find four file.css
Where and at which line do I have to enter the code?
Is it possible to use this option in the settings of the plugin?

Here’s a guide for where to put CSS:
