html+CSS3实现打火机开启关闭火焰效果

1、新建html文档。

2、书写hmtl代码。

<div class='playground'>

 <div class='flame'></div>

 <div class='lighterBody'>

  <div class='hover'> hover me </div>

 </div>

 <div class='lid'></div>

</div>

3、初始化css代码。

<style>

* { margin: 0; padding: 0 }

body { background: #cccccc; }

:before, :after { position: absolute; content: ""; }

</style>

4、书写css代码。

.playground { position: relative; width: 140px; height: 400px; left: 50%; margin-left: -70px; }

.flame { opacity: 0; position: absolute; bottom: 60%; left: 42%; width: 14px; height: 70px; background-color: white; border-radius: 100% 100% 0 0; box-shadow: 0 0 20px #FFFEF0, 0 0 20px #FFFEE6, 0 0 20px #fefcc9, 10px -10px 30px #feec85, -20px -20px 40px #ffae34, 20px -40px 50px #ec760c, -20px -60px 60px #cd4606, 0 -80px 70px #973716, 10px -90px 80px #451b0e; animation: flame 3s infinite linear; }

.lighterBody { position: absolute; width: 140px; height: 130px; top: 200px; left: 0; background: linear-gradient(to right, #959595 0%, #0d0d0d 46%, #010101 50%, #0a0a0a 53%, #4e4e4e 76%, #383838 87%, #1b1b1b 100%); border-radius: 2% 2% 8% 8%; box-shadow: inset 0 0 5px 5px #333333; }

.playground:hover .flame { opacity: 1; transition: 0.4s linear; }

.playground:hover .lid { animation: lidOff 0.3s linear; animation-fill-mode: forwards; }

.hover { text-align: center; margin-top: 30%; font-family: 'Sonsie One', cursive; font-size: 19px; color: rgba(255, 255, 255, 0.9); text-shadow: 0 1px 1px rgba(0, 0, 0, 0.8); }

.hover:before { z-index: 1; width: 0; height: 0; top: -50px; left: 20px; border-bottom: 35px solid #f2f2f2; border-left: 22px solid transparent; }

.lid { z-index: 2; position: absolute; width: 140px; height: 75px; top: 125px; left: 0; background: linear-gradient(to right, #959595 0%, #0d0d0d 46%, #010101 50%, #0a0a0a 53%, #4e4e4e 76%, #383838 87%, #1b1b1b 100%); border-radius: 8% 8% 2% 2%; box-shadow: inset 0 0 5px 5px #333333; }

.lid:before { width: 10px; height: 10px; top: 70px; left: 133px; background: radial-gradient(ellipse at center, #959595 0%, #0d0d0d 46%, #010101 50%, #0a0a0a 53%, #4e4e4e 76%, #383838 87%, #1b1b1b 100%); border-radius: 100%; }

 @keyframes flame {  0% {

 height: 70px;

 transform: skewY(0deg);

 border-radius: 100% 100% 0 0;

}

 25% {

 height: 60px;

 transform: skewY(40deg);

 border-radius: 10% 100% 0 0;

}

 60% {

 height: 65px;

 transform: skewY(-20deg);

 border-radius: 90% 10% 0 0;

}

 70% {

 height: 50px;

 transform: skewY(10deg);

 border-radius: 10% 100% 0 0;

}

 100% {

 height: 70px;

 transform: skewY(0deg);

}

}

@keyframes lidOff {  from {

 transform: rotate(0deg);

 transform-origin: 100% 100%;

}

to { transform: rotate(130deg); transform-origin: 100% 100%; }

}

5、代码整体结构。

6、查看效果。
