1. Advantages of CSS3 rotating background

1. Enhance the three-dimensional sense of the page: CSS3 rotating background can make a simple flat background pattern three-dimensional, thereby enhancing the three-dimensional sense of the page.
2. Achieve dynamic effects: CSS3 rotating background can achieve dynamic effects, making the page more lively and interesting and attracting the user's attention.

The transform attribute is important for realizing rotating background in CSS3 Attributes, which can achieve effects such as rotation, scaling, and movement of elements. A rotation effect can be easily achieved by applying the transform attribute to the background pattern in the element.

background:url(../images/bg.jpg) no-repeat center center fixed;
-webkit-transform: rotate(30deg);
-moz-transform: rotate(30deg);
-ms-transform: rotate(30deg);
-o-transform: rotate(30deg);
transform: rotate(30deg);

In the above code, the background attribute is used to set the background pattern of the element, and the transform attribute is used to implement Rotation operation. Different browsers support different transform attributes, so multiple methods are needed for compatibility.

2. Use the animation attribute for animation

In addition to using the transform attribute for rotation, you can also use the animation attribute to achieve dynamic effects of rotation. The animation attribute can set the animation effect of the element, including time, delay, and speed, so as to achieve more flexible animation effects.

background: url(../images/bg.jpg) no-repeat center center fixed;
animation: rotate 5s linear infinite;
-webkit-animation: rotate 5s linear infinite;
@keyframes rotate {
from {transform: rotate(0deg);}
to {transform: rotate(360deg);}
}

In the above code, the animation attribute is used to set the animation effect of the element, including time , delay, speed and other parameters, while @keyframes is used to set the rotation animation effect of the element.
