    }
</style>

Sometimes we want the background image to remain motionless when scrolling the page to produce a fixed effect. By using the background-attachment attribute, we can set the scrolling method of the background image. The specific code is as follows:

<style>
    .fixed-bg {
        background-image: url("image.jpg");
        background-attachment: fixed; /* 背景固定 */
    }
</style>
