🐇🐇🐇 实现火箭炮

我把火箭炮拆成三个部分：一部分是头部的圆角三角形、一部分是火箭炮火药桶、一部分是火箭炮导火线。

火箭炮的代码如下

<div class="rocketGun" id="rocketGun">
    <div class="gradient">
        <div class="bg"></div>
    </div>
    <div class="cylinder" id="cylinder">
        <div class="cylinderLi"></div>
        <div class="cylinderLi"></div>
        <div class="cylinderLi"></div>
        <div class="cylinderLi"></div>
    </div>
    <div class="woodStick">
    </div>
    <div class="firewire" id="firewire">
        <div class="imgs" id="imgs">
            <img src="./img/firewire.png">
            <img src="./img/firewire.png">
            <img src="./img/firewire.png">
            <img src="./img/firewire.png">

    </div>
</div>

    transform: scaleX(1.155) skewY(-30deg) rotate(-30deg) translateY(-42.3%) skewX(30deg) scaleY(0.866) translateX(-24%);
}

实现效果

火箭筒我还实现了两种效果，随机产生

🐇🐇🐇 点燃火箭炮

我找了一个中国各个城市代表的背景图，也祝祖国新年快乐！！！还跟李云龙借来了他的意大利炮按钮。整体效果如下：

点击开炮按钮就会点燃火箭炮了，效果你们自己去试试

单单实现火箭炮怎么够呢，我又用了强大的CSS实现了烟花

🐇🐇🐇 实现烟花

使用CSS的 background 仅有的特效属性linear-gradient与 radial-gradient画满整个div，实现烟花粒子效果。再配合animation将div不断放大，实现烟花绽放的效果。

代码如下：

<div class="firework" id="firework">
    <div class="rocketFirework"></div>
    <div class="rocketFirework"></div>
    <div class="rocketFirework"></div>
    <div class="rocketFirework"></div>
    <div class="rocketFirework"></div>
    <div class="rocketFirework"></div>
    <div class="rocketFirework"></div>
    <div class="rocketFirework"></div>
</div>

.firework {
    position: absolute;
    width: 100%;
    height: 100%;
    top: -16%;
    left: 50%;
    transform: translate3d(-50%, 0%, 10px) scale(0.8, 0.6);
    overflow: hidden;
    display: none;
}
@keyframes fireworks-animation {
    0% {
        transform: translate(-50%, 90vh);
        width: 4px;
        opacity: 1;
    }
    50% {
        width: 4px;
        opacity: 1;
    }
    100% {
        width: 600px;
        opacity: 0;
    }
}

.rocketFirework,
.rocketFirework::before,
.rocketFirework::after {
    content: "";
    position: absolute;
    top: 50%;
    left: 50%;
    aspect-ratio: 1;
    background:  linear-gradient(0deg, #39c0e6 80%, rgba(57, 192, 230, 0.44) 20%) 50% 00%,
    linear-gradient(0deg, #3fd1fc 100%, #101215 0%) 00% 50%,
    radial-gradient(circle at center, #d2439c 50%, #5c00fe 30%, #211122 0%) 50% 99%,
    radial-gradient(circle at center, #ff01f3 50%, #fd0094 30%, #211122 0%) 99% 50%,
    radial-gradient(circle at center, #4bf100 50%, #1b9f00 30%, #211122 0%) 80% 90%,
    radial-gradient(circle at center, #ff0044 50%, #f2052d 30%, #211122 0%) 95% 90%,
    radial-gradient(circle at center, #01d4f7 50%, #0280c2 30%, #211122 0%) 10% 60%,
    linear-gradient(0deg, #3fd1fc 100%, #101215 0%) 31% 80%,
    radial-gradient(circle at center, #d2439c 50%, #5c00fe 30%, #211122 0%) 80% 10%,
    radial-gradient(circle at center, #ff01f3 50%, #fd0094 30%, #211122 0%) 90% 23%,
    radial-gradient(circle at center, #ff01f3 50%, #fd0094 30%, #211122 0%) 45% 20%,
    radial-gradient(circle at center, #4bf100 50%, #1b9f00 30%, #211122 0%) 13% 24%;
    background-size: 8px 8px;
    background-repeat: no-repeat;
    transform: translate(-50%, -50%);
    animation: fireworks-animation 4s infinite;
}
.rocketFirework::before {
    transform: translate(-50%, -50%) rotate(25deg) !important;
}
.rocketFirework::after {
    transform: translate(-50%, -50%) rotate(-37deg) !important;
}

.rocketFirework:nth-of-type(2),
.rocketFirework:nth-of-type(2)::before,
.rocketFirework:nth-of-type(2)::after {
    top: 30%;
    left: 16%;
    animation-duration: 3.8s;
}
.rocketFirework:nth-of-type(3),
.rocketFirework:nth-of-type(3)::before,
.rocketFirework:nth-of-type(3)::after {
    top: 10%;
    left: 72%;
    animation-duration: 4.2s;
}
.rocketFirework:nth-of-type(4),
.rocketFirework:nth-of-type(4)::before,
.rocketFirework:nth-of-type(4)::after {
    top: 28%;
    left: 32%;
    animation-duration: 3.6s;
}
.rocketFirework:nth-of-type(5),
.rocketFirework:nth-of-type(5)::before,
.rocketFirework:nth-of-type(5)::after {
    top: 32%;
    left: 84%;
    animation-duration: 4.4s;
}
.rocketFirework:nth-of-type(6),
.rocketFirework:nth-of-type(6)::before,
.rocketFirework:nth-of-type(6)::after {
    top: 38%;
    left: 40%;
    animation-duration: 4.1s;
}
.rocketFirework:nth-of-type(7),
.rocketFirework:nth-of-type(7)::before,
.rocketFirework:nth-of-type(7)::after {
    top: 28%;
    left: 64%;
    animation-duration: 3.9s;
}
.rocketFirework:nth-of-type(8),
.rocketFirework:nth-of-type(8)::before,
.rocketFirework:nth-of-type(8)::after {
    top: 30%;
    left: 56%;
    animation-duration: 3.9s;
}

效果如下：

🐇🐇🐇 结尾

整体设计思想就是火箭炮开炮飞上天空后，引燃烟花的绽放。简简单单的玩法，祝大家新年快乐，新的一年里面事事顺心、再也没有bug、也能找到另一半。新的一年就到此结束了，创作不易，谢谢点赞。
