counting from negative to positive and separator style issues

[Graphicfort]

From https://codepen.io/msoler75/pen/NWLzNYj

1- separator style issue:
From the codepen example, you can see that there are space between the , and the number (99 , 999) this happened because of the width of the first span element.
Suggestion; add a class to the span element and set it's width to 0 to remove the extra spaces between the comma and the number, this will convert the number from 99 , 999 to 99,999

2- counting from negative to positive issue:
From the codepen change the code to

const counter = new CountUp("counter", 5, {
   startVal: -1,
    plugin: new Odometer({ duration: 2.3, delay: 0 }),
    duration: 3.0
});

This will shift the number 5 to the left and add extra 1 empty space the space could be different if you changed the number -1 to -10, this will shift the number 5 to the left by 2 spaces, this happened because the length of the negative number greater than the positive number
