元宵节给网站挂个灯笼

元宵节将至，给网站挂个灯笼，也增加点节日气氛。喜欢的朋友们可以自己复制代码调试一下，样式也可以自己修改。 效果图如下：

在网上参考了相关代码，实现方式很简单，首先添加一张背景图片，代码实现过程如下：

`body {
        background: url("./test.png");
        -webkit-background-size: cover;
        -o-background-size: cover;
        background-size: cover;
    }
 <div class="lantern-box">
    <div class="lantern">
        <div class="lines"></div>
        <div class="lantern-a">
            <div class="lantern-b">
                <div class="lantern-t">元</div>
            </div>
        </div>
        <div class="spike spike-a">
            <div class="spike-c"></div>
            <div class="spike-b"></div>
        </div>
    </div>
</div>
<div class="lantern-box1">
    <div class="lantern">
        <div class="lines"></div>
        <div class="lantern-a">
            <div class="lantern-b">
                <div class="lantern-t">宵</div>
            </div>
        </div>
        <div class="spike spike-a">
            <div class="spike-c"></div>
            <div class="spike-b"></div>
        </div>
    </div>
</div>  `

灯笼是用css样式画出来的，之前以为网上画的灯笼都是图片，原来都是用样式实现的，代码如下： `

  .lantern-box {
        position: relative;
        top: 20px;
        left：-30px;
        z-index: 999;
    }

    .lantern-box1 {
        position: fixed;
        top: 20px;
        right: 0px;
        z-index: 999;
    }

    .lantern-box1 .lantern {
        position: relative;
        width: 120px;
        height: 90px;
        margin: 50px;
        background: #d8000f;
        background: rgba(216, 0, 15, 0.8);
        border-radius: 50% 50%;
        -webkit-transform-origin: 50% -100px;
        -webkit-animation: swing 5s infinite ease-in-out;
        box-shadow: -5px 5px 30px 4px rgba(252, 144, 61, 1);
    }

    .lantern {
        position: relative;
        width: 120px;
        height: 90px;
        margin: 50px;
        background: #d8000f;

        -webkit-transform-origin: 50% -100px;
        -webkit-animation: swing 3s infinite ease-in-out;
        box-shadow: -5px 5px 50px 4px rgba(250, 108, 0, 1);
    }

    .lantern-a {
        width: 100px;
        height: 90px;
        background: #d8000f;

        margin: 12px 8px 8px 8px;
        border-radius: 50% 50%;
        border: 2px solid #dc8f03;
    }

    .lantern-b {
        width: 50px;
        height: 90px;
        background: #d8000f;
        background: rgba(216, 0, 15, 0.1);
        margin: -4px 8px 8px 26px;
        border-radius: 50% 50%;
        border: 2px solid #dc8f03;
    }

    .lines {
        position: absolute;

        background: #ffa500;
        border-radius: 0 0 5px 5px;
    }

    .spike-b {
        position: absolute;
        top: 14px;
        left: -2px;
        width: 10px;
        height: 10px;
        background: #dc8f03;
        border-radius: 50%;
    }

    .spike-c {
        position: absolute;
        top: 18px;
        left: -2px;
        width: 10px;
        height: 35px;
        background: #ffa500;

    }

    .lantern:before {

        top: -7px;
        left: 29px;
        height: 12px;
        width: 60px;
        content: " ";

    .lantern:after {

        bottom: -7px;
        left: 10px;
        height: 12px;

        background: #ffa500;
        background: linear-gradient(to right, #dc8f03, #ffa500, #dc8f03, #ffa500, #dc8f03);
    }

    .lantern-t {
        font-family: 华文行楷, Arial, Lucida Grande, Tahoma, sans-serif;
        font-size: 3.2rem;
        color: #dc8f03;
        font-weight: bold;
        line-height: 85px;
        text-align: center;
    }

    .night .lantern-t,
    .night .lantern-box,
    .night .lantern-box1 {
        background: transparent !important;
    }

` 动画效果也是用css实现的，代码如下：

    `@-moz-keyframes swing {
        0% {
            -moz-transform: rotate(-10deg)
        }

        50% {
            -moz-transform: rotate(10deg)
        }

        100% {
            -moz-transform: rotate(-10deg)
        }
    }

    @-webkit-keyframes swing {
        0% {
            -webkit-transform: rotate(-10deg)
        }

        50% {
            -webkit-transform: rotate(10deg)
        }

        100% {
            -webkit-transform: rotate(-10deg)
        }
    }`
