I know there's several questions on this, but I'm struggling to find out how to use Math.random to get random numbers between two high integers?

So, for example, between 50 and 80. I thought this would work...

'left': Math.floor((Math.random() * 80) + 50) + '%'

Any ideas?

You need to know the range of the random.

Between 50 and 80, the range is 30 (80 - 50 = 30), then you add 1.

Therefor, the random would look like this :

Math.floor(Math.random() * 31) + 50
