Multiples iterations of a CSS class for re-use multiple times

Question

I have a basic webpage which I'm trying to show progress/completion status of one background task by using CSS from this Liquid bubble progress bar.

Further, I have multiple such background tasks and I want to show progress of each in the same html webpage by using another copy of that bubble progress bar. Say like I want to have 5 such bubbles and each showing progress of 5 independent tasks, I guess I have to copy paste the CSS of 1 bubble and change from name x to y for 5 times and use the 5 new names accordingly. Which is not right way to do.

Is there a way where i can replicate it for T times with a new names using javascript or something or any easy methods?

Please could I get some help to make the right javascript code and the right function calls to achieve that. Thanks heaps in advance.

Below is the CSS code from the source.

@import "nib"

@keyframes spin
  from
    transform rotate(0deg)
  to
    transform rotate(360deg)

 placeholder()
  ::-webkit-input-placeholder
    {block}

  // Progress Bar

  progress-border-size = 5px
  progress-inner-border-size = 5px
  progress-inner-size = progress-size - (progress-border-size + progress-inner-border-size)
  progress-inner-border = progress-inner-border-size solid page-background-color

  progress-alpha = 50%
  progress-level-change-speed = 1s

this should help you to get the idea. what I did is mapped the bubble with input using a custom attribute and then binding the click and change events using the custom attribute groupid

var colorInc = 100 / 3;

$(function() {
  $(".percent-box").each(function() {
    $(this).click(function() {
      $(this).select();
    });
  })


  $(".percent-box").each(function() {
    $(this).keyup(function() {
      var val = $(this).val();
      var groupId = $(this).attr('group'); // get the group id to correctly target the liquid bubble
      if (val <= 100 &&
        val >= 0) {}
      if (val != "" &&
        !isNaN(val) &&
        val <= 100 &&
        val >= 0) {
        //console.log(val);
        var valOrig = val;
        val = 100 - val;
        if (valOrig == 0) {
          $("[group=" + groupId + "] .percent-box").val(0);
          $("[group=" + groupId + "] .progress .percent").text(0 + "%");
        } else $("[group=" + groupId + "] .progress .percent").text(valOrig + "%");

        $("[group=" + groupId + "]  .progress").parent().removeClass();
        $("[group=" + groupId + "] .progress .water").css("top", val + "%");

        if (valOrig < colorInc * 1)
          $("[group=" + groupId + "] .progress").parent().addClass("red");
        else if (valOrig < colorInc * 2)
          $("[group=" + groupId + "]  .progress").parent().addClass("orange");
        else
          $("[group=" + groupId + "]  .progress").parent().addClass("green");
      } else {
        $("[group=" + groupId + "] .progress").parent().removeClass();
        $("[group=" + groupId + "] .progress").parent().addClass("green");
        $("[group=" + groupId + "] .progress .water").css("top", 100 - 67 + "%");
        $("[group=" + groupId + "] .progress .percent").text(67 + "%");
        $("[group=" + groupId + "].percent-box").val($("[group=" + groupId + "].percent-box").attr('placeholder'));
      }
    })
  });

One way, which seems to be a common technique, is to create new STYLE tags and append them into the BODY tag.

For example - see Create classes using javascript

With that method, you could build up whatever innerHTML you wanted to construct a complete class, or set of classes, using variables where necessary.

Here's a very simple idea of how that works:

function getRandomNumber(min, max) {
    // returns a random number between min and max, inclusive
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

function createBoxes() {
  let bdy = document.body;
  for (let i = 1; i <= 5; i++) {
    let d = document.createElement("div");
    d.className = "div" + i;
    bdy.appendChild(d);
  }
  let s = document.createElement("style");
  s.type = "text/css";
  for (let i = 1; i <= 5; i++) {
    let r = getRandomNumber(0, 255);
    let g = getRandomNumber(0, 255);
    let b = getRandomNumber(0, 255);
    s.innerHTML += "\n.div" + i + "{background-color:rgb(" + r + "," + g + "," + b + "); height:100px; width:100px;}\n";
    bdy.appendChild(s);
  }
}
// for testing purposes only
window.onload = createBoxes;
