Polka Dot Background Pattern

index.html and style.css have already been provided in the VM.

To create a polka dot background pattern, you can follow these steps:

Set the background-color property to black.
Use the background-image property with two radial-gradient() values to create two dots.
Specify the pattern's size using the background-size property. Use background-position to appropriately place the two gradients.
Set background-repeat to repeat.
Note that the fixed height and width of the element is for demonstration purposes only.

Here's an example HTML code for a div element with class polka-dot:

<div class="polka-dot"></div>

And here's the corresponding CSS code:

.polka-dot {
  width: 240px;
  height: 240px;
  background-color: #000;
  background-image:
    radial-gradient(#fff 10%, transparent 11%),
    radial-gradient(#fff 10%, transparent 11%);
  background-size: 60px 60px;
  background-position:
    0 0,
    30px 30px;
  background-repeat: repeat;
}
