Set breakpoints in REM instead

[aceres]

Hello Everyone,

According to documentation: "options", I see that I can add different breakpoints for this slider. It works very well. I did check the type that breakpoint value also can be a string? Is that correct?

See link attached:
https://splidejs.com/guides/options/#breakpoints

{ perPage: 4, breakpoints: { 640: { perPage: 2, }, } }

My question now: Can I use string for REM there? Instead of 640, I want to set: '40rem'. I see that this doesn't work. Any idea why?

{ perPage: 4, breakpoints: { '40rem': { perPage: 2, }, } }

Is this past of best practices? Breakpoints are meant to be fixed breaking points with pixel values, not relative values, I think.
