slider.css | HTML presentation without javascript

I am working on a photo editing page. The goal is for users to be able to adjust parameters such as hue, saturation, brightness by uploading pictures and then editing them using range sliders. In order to ensure the program worked well on mobile browsers I decided to use the rangeslider.js library. After getting an initial slider up and working I decided to try more advanced designs. I found this design online and like it. My goal now is to have multiple slider each which displays its value like the linked slider. I am having trouble achieving this. To keep things simple I am currently formatting my slider using the standard css from rangeslider.js. I am able to create a single slider which behaves like the one in the linked design, but now I want to generalize this to multiple sliders, which is where I am having trouble. In the single design the code relevant to creating the rangeslider is

here i need to control carousel slides with custom buttons i achieved this with the help of this Example.

This is the code for it..

I am using npm package vue-custom-range-slider but i have one problem my slider is divided into four colors blue, green, yellow, red it looks like this

Minimum number 19 and maximum number 65

Imagine that a person can choose a certain age blue color is a range from 19 to 21 green 22 to 30 yellow 31 to 49 and the last red is above 50 for a more understandable example you can see this picture

I used a linear-gradient to split the slider into four slider colors, Now let me explain the problem.

I need to make the numbers for the blue range, that is, the numbers from 19 to 21 are inside the blue, 22 - 30 are inside the green 31-49 are inside the yellow, and above 50 are inside the red

Because at the moment the numbers are set incorrectly at the moment, for example, the numbers for blue are set from 19 to 30 and so on with all

I recommend looking at this code in codesandbox for a better understanding.

I am trying to get @typeform/embed to work in React. I want to see them all before deciding which one is best for the case where I want to use it.

All types are imported and css is imported:

I have no clue when it comes to javascript but a client asked me if I could get this slider to autoplay. If anyone could help it would be awesome. I have tried to get it to work but to no avail so I decided to ask for help here.

my js doesn't work in my dynamic web project if I linked it from a jsp, but if i put it in the jsp it works fine. Same for every js code. I don't know what to do, jquery is imported... The javascript code is correct because it work fine in the same jsp, but if I put it in a *.js file it doesn't work. Here's my code:

I can't find reason why it's not working on safari lower then 14. After trying to fix it and looking in Google I give up.

It works everywhere except mine iPad 2, where is safari 13.3.1. I checked more iOS devices with Safari under 14 and there was same issue.

It's working fine on version over 14.

Here is a cleaned up code

JavaScript

Is it possible to make a multicolor "selected region" for the seiyria-bootstrap-slider?

Maybe someone is able to help me. I will attach below my project example, so u can try and test.

Multicolor example

I am trying to use session storage to save the values of the slider on my browser. On page reload I keep getting my default 0.5 being displayed. The script seems fine, I am wondering if using a "change" event is not the best approach.
