1.实现效果
2.实现步骤
- 定义一个灯笼的背景色bg，线条颜色lineColor
:root {
--lineColor: #ecaa2f;
--bg: #f00;
}
- 父容器container宽高设置为200px/150px
.container {
width: 200px;
height: 150px;
position: relative;
}
- 在父容器内添加一个圆角矩形，宽高为父容器一致，设置一定的圆角与box-shadow阴影，背景色为 bg
<div class="container">
<div class="center"></div>
</div>
.center {
position: relative;
width: 100%;
height: 100%;
background: var(--bg);
border-radius: 120px;
box-shadow: 0 0 80px -10px var(--bg);
}
- 在center中添加一个标签，宽高与父容器一致，在其前后伪元素上绘制灯笼上的线条
<div class="center">
<div class="center-line"></div>
</div>
.center-line {
width: 100%;
height: 100%;
}
- 在center-line的前伪元素上添加一个圆环，高度与父容器一致，宽度为150px；边框设置为2px，颜色为lineColor，距离顶部为0，水平居中
.center-line::before {
content: "";
position: absolute;
top: 0;
left: calc(50% - 75px);
width: 150px;
height: 150px;
border: 2px solid var(--lineColor);
border-radius: 50%;
}
- 在center-line的后伪元素上添加一个圆环，高度与父容器一致，宽度为70px；边框设置为2px，颜色为lineColor，距离顶部为0，水平居中
.center-line::after {
content: "";
position: absolute;
top: 0;
left: calc(50% - 35px);
width: 70px;
height: 150px;
border: 2px solid var(--lineColor);
border-radius: 50%;
}
- 在center-line中添加span标签，内容为"元旦快乐"，设置宽度与字体的font-size相同，水平垂直居中，字体颜色为lineColor
<div class="center">
<div class="center-line"><span>元旦快乐</span></div>
</div>
.center-line span {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 18px;
font-size: 18px;
color: var(--lineColor);
font-weight: bold;
}
- 为center容器添加前伪元素，宽高为80px/10px,背景色为lineColor,设置左上右上的一定的圆角弧度，水平居中，top设置为-8px，层级设置为2，居于最顶层
.center::before {
content: "";
position: absolute;
top: -8px;
left: calc(50% - 40px);
width: 80px;
height: 10px;
background: var(--lineColor);
border-radius: 5px 5px 0 0;
z-index: 2;
}
- 为center容器添加后伪元素，宽高为80px/10px,背景色为lineColor,设置左下右下的一定的圆角弧度，水平居中，bottom设置为-8px，层级设置为2，居于最顶层
.center::after {
content: "";
width: 80px;
height: 10px;
background: var(--lineColor);
border-radius: 0 0 5px 5px;
position: absolute;
bottom: -8px;
left: calc(50% - 40px);
z-index: 2;
}
- 在最外层的父容器container中添加一个标签，用来绘制灯笼最上面的线条
<div class="container">
+ <span class="head-line"></span>
</div>
.head-line {
position: absolute;
left: calc(50% - 2px);
top: -60px;
width: 4px;
height: 60px;
background-color: var(--lineColor);
}
- 在center中添加一个标签，用来绘制灯笼下面的线条
<div class="center">
+ <span class="footer-line"></span>
</div>
.footer-line {
position: absolute;
left: calc(50% - 2px);
bottom: -50px;
width: 4px;
height: 50px;
background-color: var(--lineColor);
z-index: -1;
}
- 为footer-line添加一个伪元素，用来绘制灯笼最下面的细须，用linear-gradient设置背景色，这样一个灯笼就绘制完成了，接下来我们给灯笼添加上动画效果
.footer-line::after {
content: "";
position: absolute;
bottom: -75px;
left: calc(50% - 8px);
width: 16px;
height: 80px;
background: linear-gradient(
#f00,
#e36d00 3px,
#fbd342 5px,
#e36d00 8px,
#e36d00 12px,
#f00 16px,
rgba(255, 0, 0, 0.8) 26px,
rgba(255, 0, 0, 0.6)
);
border-radius: 5px 5px 0 0;
}
- 添加rotate动画，动画的0%和100%旋转-10deg，50%的时候旋转10deg
@keyframes rotate {
0%,
100% {
transform: rotate(-10deg);
}
50% {
transform: rotate(10deg);
}
}
- 为灯笼底部的细须添加旋转动画
.footer-line {
+ animation: rotate 3s infinite ease-in-out;
}
- 为灯笼的中间区域center添加旋转动画
.center {
+ animation: rotate 3s infinite ease-in-out;
}
- 可以看到，灯笼中间与上方线条之间摆动的幅度太大，为center设置transform-origin
.center {
+ transform-origin: top center;
}
- 为最外层父容器添加旋转动画，就实现好了啦~
.container {
+ animation: rotate 3s infinite ease-in-out;
}
3.实现代码
