Trying to build a dice game using front end languages i.e html,css and javascript

Question

I am trying to develop a Dice game where the two dice roll simultaneously and generate random numbers. Here I used 3-D dice (not using Dice images) everything is working fine. I want to add one more thing: I want the numbers to appear on the front face of the dice on the screen like for example - 'the numbers are 2,3 or 4,5'. I need help in writing this code.

I don't know where to start. I want to do this using JavaScript, HTML, CSS.

function rollDice() {
  const dice = [...document.querySelectorAll(".die-list")];
  dice.forEach(die => {
    toggleClasses(die);
    die.dataset.roll = getRandomNumber(1, 6);
  });
}

function toggleClasses(die) {
  die.classList.toggle("odd-roll");
  die.classList.toggle("even-roll");
}

function getRandomNumber(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

document.getElementById("roll-button").addEventListener("click", rollDice);

**CSS**

The code is available in this CodePen. You can have a look at the dice.

After the dice stop rolling it has to appear like below:

The Numbers Are - 2,3

The numbers are based on the front face of the dice.

You almost have it, you just need to grab the values of each dice and display them.

I added the following div with a span for each dice value. I use the ids to match which dice is which.

<div>Your values are <span id="die-1-val"></span> <span id="die-2-val"></span></div>

This is the only JS I needed to add, which I placed inside the forEach.

document.getElementById(die.id+"-val").innerText = die.dataset.roll;

Working example...

function rollDice() {
  const dice = [...document.querySelectorAll(".die-list")];
  let dice1Val, dice2Val;
  dice.forEach(die => {
    toggleClasses(die);
    die.dataset.roll = getRandomNumber(1, 6);
    document.getElementById(die.id+"-val").innerText = die.dataset.roll;
  });
}

function toggleClasses(die) {
  die.classList.toggle("odd-roll");
  die.classList.toggle("even-roll");
}

function getRandomNumber(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

document.getElementById("roll-button").addEventListener("click", rollDice);
