Creating a basic HTML/Javascript Leaderboard

Question

Whether or not it's easily possible and done with Javascript I'm not sure but..

As shown in the code below, I've 5 players, each with a different score. I'm looking to code it so that it will automatically relist the players based off how high their score is. IDEALLY, I would also want to colour the first 3 rows to be gold-silver-bronze if that was possible.

Any help making this or pointing me in the right direction would be much appreciated. I'm not sure where I should start.

#container {
	width: 600px;
	height: auto;
}

.row {
	position: relative;
	display: block;
	width: 100%;
	height: 40px;
	border-bottom: 1px solid #AFAFAF;
}

.name {
	position: relative;
	display: inline-block;
	width: 75%;
	line-height: 45px;
}

.score {
	position: relative;
	display: inline-block;
	width: 25%;
}

<div id="container">
    <div class="row">
        <div class="name">Player1</div><div class="score">430</div>
    </div>
    
    <div class="row">
        <div class="name">Player2</div><div class="score">580</div>
    </div>
    
    <div class="row">
        <div class="name">Player3</div><div class="score">310</div>
    </div>
    
    <div class="row">
        <div class="name">Player4</div><div class="score">640</div>
    </div>
    
    <div class="row">
        <div class="name">Player5</div><div class="score">495</div>
    </div>
</div>

You can make the first 3 rows the color you want by using nth-child()

/* Gold */
.row:nth-child(1) {background: gold;}
/* Silver */
.row:nth-child(2) {background: #c0c0c0;}
/* Bronze */
.row:nth-child(3) {background: #cd7f32;}

Next to sort the items you can put the rows into an array, then use sort to sort the items.

document.addEventListener('DOMContentLoaded', () => {
  let elements = []
  let container = document.querySelector('#container')
  // Add each row to the array
  container.querySelectorAll('.row').forEach(el => elements.push(el))
  // Clear the container
  container.innerHTML = ''
  // Sort the array from highest to lowest
  elements.sort((a, b) => b.querySelector('.score').textContent - a.querySelector('.score').textContent)
  // Put the elements back into the container
  elements.forEach(e => container.appendChild(e))
})

#container {
  width: 600px;
  height: auto;
}

.row {
  position: relative;
  display: block;
  width: 100%;
  height: 40px;
  border-bottom: 1px solid #AFAFAF;
}

.name {
  position: relative;
  display: inline-block;
  width: 75%;
  line-height: 45px;
}

.score {
  position: relative;
  display: inline-block;
  width: 25%;
}

.row:nth-child(1) {
  background: gold;
}

.row:nth-child(2) {
  background: #c0c0c0;
}

.row:nth-child(3) {
  background: #cd7f32;
}

<div id="container">
  <div class="row">
    <div class="name">Player1</div><div class="score">430</div>
  </div>

  <div class="row">
    <div class="name">Player2</div><div class="score">580</div>
  </div>

  <div class="row">
    <div class="name">Player3</div><div class="score">310</div>
  </div>

  <div class="row">
    <div class="name">Player4</div><div class="score">640</div>
  </div>

  <div class="row">
    <div class="name">Player5</div><div class="score">495</div>
  </div>
</div>
