In web design, background effects are a very important part, it can add a vivid atmosphere to the website. Improve user experience. As a key language for web page style design, CSS gives full play to flexibility and diversity, and provides a wealth of attributes and techniques to create various dynamic background effects.

Gradient background can add charm to the web page and make the page appear more three-dimensional and vivid. CSS provides two commonly used gradient methods: linear-gradient and radial-gradient. Here is a sample code using a gradient background:

@keyframes bg-move {
  from {
    background-position: 0 0;
  }
  to {
    background-position: 100% 100%;
  }
}

.animated-bg {
  background-image: url('bg-image.jpg');
  animation: bg-move 10s infinite alternate;
}

The shadow effect can make the web page look more three-dimensional and rich. Through the box-shadow attribute, we can achieve various cool shadow background effects. Here is a simple example code:

.shadow-bg {
  box-shadow: 0 0 20px rgba(0, 0, 0, 0.5);
}
