Not sure what to use for the overlay color, we changed bg-emphasis to a fitting color
maybe background overlay would be a better name?

• The demo will be automatically updated after the merge, you don't have to commit it.
• There is a merge conflict
• A bit of info with some links to the files in the readme would be nice

Fixed the conflict
shouldn't the demo be in the gitignore then?

I'll merge it, but 1 thing left: the z-indexes. Let's also apply this: rapidez/core#625 here with an updated readme to include the variables within the tailwind.config.js. Could you arrange that in a new PR @JimmyHoenderdaal?

Now this is merged; this needs te be replaced within Rapidez? See: https://github.com/rapidez/core/tree/master/resources/views/components/slideover. Could you arrange that @JimmyHoenderdaal?
