代码解读
定义一个名为 box 的容器:
<div class="box">
</div>
内容居中显示:
html,
body {
height: 100%;
display: flex;
align-items: center;
justify-content: center;
}
画条纹背景:
.box {
width: 300px;
height: 300px;
background: linear-gradient(
-45deg,
white 0%,
white 25%,
hotpink 25%,
hotpink 50%,
white 50%,
white 75%,
hotpink 75%,
hotpink 100%);
background-size: 10%;
}
在 box 容器内定义一个名为 content 的容器:
<div class="box">
<div class="content">
</div>
</div>
box 容器留出厚边框,content 容器嵌在其中:
.box .content {
height: 100%;
display: flex;
align-items: center;
justify-content: center;
}
.box {
box-sizing: border-box;
padding: 15px;
}
.box .content {
background-color: white;
}
设置厚边框的立体效果:
.box,
.box .content {
box-shadow: 0 0 2px deeppink,
0 0 5px rgba(0, 0, 0, 1),
inset 0 0 5px rgba(0, 0, 0, 1);
border-radius: 10px;
}
content 容器中增加内容:
<div class="box">
<div class="content">
<h2>What is Lorem Ipsum?</h2>
<p>Mauris volutpat risus quis nisi tempus hendrerit. Nullam nisi urna, suscipit quis risus sed, congue congue quam. Morbi sit amet suscipit ex. Vivamus vel nulla ac libero volutpat ultrices.</p>
</div>
</div>
内容布局:
.box .content {
flex-direction: column;
box-sizing: border-box;
padding: 30px;
text-align: center;
font-family: sans-serif;
}
.box .content h2 {
color: deeppink;
}
.box .content p {
color: dimgray;
}
定义动画效果:
@keyframes animate {
from {
background-position: 0;
}
to {
background-position: 10%;
}
}
最后,把动画效果应用到 box 容器上:
.box {
animation: animate 2s linear infinite;
}
大功告成!
