CSS

Container class – Think of it as the bedrock of your layout. It is wide enough to hold everything you need in visibility and place it in the best way possible. Let’s make sure it is spacious, centered, and happy to be out there!
Color-container class – Here is where the fun begins! This container shall be an arena of brilliant colors that change with time. Smooth, clean, and dynamic transitions that animate your colors bringing your page to life, that is what we mean!

				
					body {
    margin: 0;
    font-family: cursive;
  }
  
  h1 {
    text-align: center;
  }
  
  .container {
    display: flex;
    flex-wrap: wrap;
    justify-content: center;
  }
  
  .color-container {
    background-color: orange;
    width: 300px;
    height: 150px;
    color: white;
    margin: 5px;
    display: flex;
    justify-content: center;
    align-items: center;
    font-size: 25px;
    text-shadow: 2px 2px 4px rgba(0, 0, 0, 0.5);
    border: solid black 2px;
    border-radius: 10px;
  }

JavaScript

First, use the querySelector to create a container called ContainerA that will hold everything.
Next, create 12 color blocks inside that container, each one as follows: create a div with a class color-container and append it to the ContainerA.
Then create a function generateColors() which will be responsible for generating random colors for each of these blocks.
All the random color magic will go on here! Inside this function, we’ll have it grab each block, generate a random color code, and style it with that color.
Now, the randomColor() function actually produces a new hex color code each time it is called. So, the randomness will add that little twinkling touch!

				
					const containerA = document.querySelector('.container');  

for(index = 0; index < 12 ; index++){
    const colorContainerA = document.createElement('div');
    colorContainerA.classList.add("color-container");
    containerA.appendChild(colorContainerA);
}

const colorContainers = document.querySelectorAll('.color-container');

generateColors();

function generateColors(){
    colorContainers.forEach(colorContainerA => {
        const newColorCode = randomColor();
        colorContainerA.style.backgroundColor = "#" + newColorCode;
        colorContainerA.innerText = "#" + newColorCode;
    });
}

function randomColor(){
    const chars = "0123456789ABCDEF";
    const colorCodeLenght = 6;
    let colorCode = "";
    for (index = 0 ; index < colorCodeLenght; index++){
        const randomNum = Math.floor(Math.random()* chars.length);
        colorCode += chars.substring(randomNum, randomNum + 1);
    }
    return colorCode;
}
