Sass Maps

So, I'm having trouble understanding this.

So, if it's less than 'sm' $break it'll apply the 'xs' breakpoint.

But it's it's greater than 'sm' will it just apply the 'med' or will it instinctively know to apply the 'lg' $break. Or would I have to apply that logic to the mixin?

You're still passing the $break to the mixin from the previous videos, so the function is aware of whether this is applying to a xs, sm, med, or lg screen. In this lesson, the variables at the top are using that value to pull back a number from the map. Once the number values are returned, the if-statement is then checking whether the statement is less than the value returned by 'sm'.

essentially in pseudo-code: if the value returned is less than small return the media query with max-width of the value else (you don't have to write this in the code, but if all other situations: greater than or equal to small) return the media query with min-width of the value
