定义 dom,一个容器中包含一个 span,span 内有文字:
<div class="book">
    <span>HTML</span>
</div>居中显示:
html, body {
    width: 100%;
    height: 100%;
    display: flex;
    align-items: center;
    justify-content: center;
    background: linear-gradient(to top left, white, dimgray);
}画出书的正面:
.book {
    width: 12rem;
    height: 18rem;
    background: linear-gradient(navy, deeppink, tomato);
    transform: skewY(-10deg);
}画出书的侧面:
.book {
    position: relative;
}
.book::before {
    content: '';
    position: absolute;
    width: 1.5rem;
    height: 100%;
    background: linear-gradient(navy, deeppink, tomato);
    top: 0;
    left: -1.5rem;
    transform: skewY(45deg);
    transform-origin: right;
    filter: brightness(0.6);
}画出书的顶面:
.book::after {
    content: '';
    position: absolute;
    width: 100%;
    height: 1.5rem;
    background: white;
    top: -1.5rem;
    left: 0;
    transform-origin: bottom;
    transform: skewX(45deg);
    filter: brightness(0.9);
}给图书加阴影,让它显得更立体:
.book {
    box-shadow: -10px 5px 30px rgba(0, 0, 0, 0.5);
}设置文字样式:
.book span {
    color: whitesmoke;
    font-size: 2.2rem;
    font-family: sans-serif;
    display: block;
    background: silver;
    text-align: center;
    height: 8rem;
    margin-top: 5rem;
    padding-top: 2rem;
    box-sizing: border-box;
    text-shadow: -2px 2px 10px rgba(0, 0, 0, 0.3);
    position: absolute;
    width: 100%;
}画出文字侧面,与画图书侧面的方法相似:
.book span {
    position: relative;
}
.book span::before {
    content: '';
    position: absolute;
    width: 1.5rem;
    height: 100%;
    background: silver;
    top: 0;
    left: -1.5rem;
    transform-origin: right;
    transform: skewY(45deg);
    filter: brightness(0.6);
}文字下增加一行小字号文字:
.book span::after {
    content: 'development';
    display: block;
    font-size: 1rem;
}dom 改为 3 本书,包含在一个容器之中,并且分别命名样式类:
<div class="books">
    <div class="book html">
        <span>HTML</span>
    </div>
    <div class="book css">
        <span>CSS</span>
    </div>
    <div class="book js">
        <span>JavaScript</span>
    </div>
</div>3 本书布局:
.books {
    display: flex;
    width: calc(12rem * 3 + 3rem * 2);
    justify-content: space-between;
    margin-top: 6rem;
}
.book:nth-child(2) {
    top: -3rem;
}
.book:nth-child(3) {
    top: -6rem;
}3 本书配色:
.book.html span,
.book.html span::before {
    background: orange;
}
.book.css span,
.book.css span::before {
    background: yellowgreen;
}
.book.js span,
.book.js span::before {
    background: royalblue;
}设置 3 本书的小字号文字:
.book.html span:after {
    content: '<devolopment />';
}
.book.css span::after {
    content: '.devolopment::';
}
.book.js span::after {
    content: '{ devolopment }';
}最后,为图书增加鼠标划过效果:
.book {
    transition: 0.3s;
}
.book:hover {
    margin-top: -1.5rem;
}大功告成!
