Change backgroup irs-line dinamic

[marcelod]

Hello everyone, what I need is for the backgroud color to be displayed according to the selection. For example, if I'm at 20, only red should be displayed, if I'm at 50, red and orange and so on.

Here's a start of what I tried to do.

I would look at using the onChange function to look at the current value, and then update the CSS to match what your expecting.
