① Dynamic Shadow

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

To create a shadow that is based on the colors of an element, follow these steps:

1. Use the ::after pseudo-element with position: absolute and width and height set to 100% to fill the available space in the parent element.

2. Inherit the background of the parent element by using background: inherit.

3. Slightly offset the pseudo-element using top. Then, use filter: blur() to create a shadow, and set opacity to make it semi-transparent.

4. Position the pseudo-element behind its parent by setting z-index: -1. Set z-index: 1 on the parent element.

Here's an example HTML and CSS code:

<div class="dynamic-shadow"></div>

.dynamic-shadow {
  position: relative;
  width: 10rem;
  height: 10rem;
  background: linear-gradient(75deg, #6d78ff, #00ffb8);
  z-index: 1;
}

.dynamic-shadow::after {
  content: "";
  width: 100%;
  height: 100%;
  position: absolute;
  background: inherit;
  top: 0.5rem;
  filter: blur(0.4rem);
  opacity: 0.7;
  z-index: -1;
}
