Pricing component done by Vanilla JS

Hi guys.

This was very challenging for me as I was struggling with writing proper JS code to make all the components as functional as they should be. It was hard figuring out how to change text values not only by clicking the toggle button, but also by changing values on the input bar.

Other hard thing for me was figuring out how to style the input range properly, after all I solved it by creating 2 divs underneath the input slider. Is there any better solution?

My code looks like a mess at the end, but the solution seems good.

Any suggestions are welcome!

Edit: The input bar is displayed differently in firefox and chrome, any suggestions how to solve cross-browser problems?

Edit 2: I added some -webkit- properties and now it seems to work at all browsers, if anyone is struggling with styling the range bar i reccomend this article
