In web design, full-screen background layout is a common and cool effect that can better display the website content, giving users a good visual experience. This article will introduce how to use HTML and CSS to implement a full-screen background layout, and provide specific code examples.

<head>
    <meta charset="UTF-8">

    <link rel="stylesheet" href="styles.css"> <!-- 引入CSS文件 -->
</head>

}

.container {
    background-image: url('background.jpg');
    background-size: cover;
    background-position: center;
    height: 100%;
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    color: #fff;
    text-align: center;
}
