摘要

众所周知，网页的暗黑模式可以减少屏幕反射和蓝光辐射，减少眼睛的疲劳感，特别是在夜间使用时更为明显。其实暗黑模式也给霓虹灯效应（Neon Effect）提供了发挥的环境。

霓虹灯效应是一种视觉效果，其特点是在深色背景上使用鲜艳的颜色来产生强烈的视觉冲击。这种效应通常用于设计海报、广告、标志和网页等。霓虹灯效应的作用在于吸引人们的注意力和增强品牌形象的辨识度，因为这种效果让人印象深刻且易于记忆，本次我们盘点适合暗色模式的网页特效，还是喜欢，暗夜的你。

发光特效

暗黑模式下最炫酷的效果无外乎发光，基本上页面元素的发光需要依赖box-shadow属性：

logo {     width: 150px;     height: 150px;     background-color: #fff;        box-shadow: 120px 80px 40px 20px #0ff;     /* in order: x offset, y offset, blur size, spread size, color */     /* blur size and spread size are optional (they default to 0) */   }

这里使用多个阴影值来创建分层效果。您可以用逗号分隔多个阴影值，它们将叠加在彼此上面。

但是这种效果比较单调，box-shadow属性只会保持所在的元素的形状上发光，如果我们想让一个元素的发光效果比较有层次感，那么就需要border-radius属性的配合。

我们可以通过给出多组值（用逗号分隔）来在一个元素上堆叠多个发光效果。发光效果将首先堆叠在顶部，最后一个堆叠在底部：

div {     width: 40px;     height: 40px;     border-radius: 50%;     background-color: #fff;     box-shadow:       0 0 60px 30px #fff,  /* inner white */       0 0 100px 60px #f0f, /* middle magenta */       0 0 140px 90px #0ff; /* outer cyan */   }

说白了就是渐进的光晕效果，最内层往最内层逐渐减淡：

配合动画特效，比如animation属性：

.logo {  pointer-events: auto;   font-size: 1rem;   width: 2.5em;   height: 9em;   transform-origin: center top;   animation: swing 3s ease-in-out infinite alternate;   position: absolute;   left: calc(50% - 1.3rem);   top: calc(clamp(4em,8vmin,12vw) + .5rem);   transform-style: preserve3d;   transition: transform .5s ease-out;   cursor: pointer;   display: block;   background: 0 0;   border: none;   -webkit-appearance: none;   padding: 0;  }

随后结合box-shadow：

.light-bulb__image:before {   content: "";   position: absolute;   left: calc(50% - 1px);   bottom: 0;   width: .625em;   height: .625em;   background: 0 0;   border-radius: 50%;   z-index: -1;   box-shadow: 0 0 6.375em 4em #00fdcf;   opacity: .6;   transform: scaleY(.7) translateY(-1em) translateX(.4em);   transform-origin: center top;   }

我们就可以营造出这种“冷灯看剑，剑上几番功名”的特效：

对于SVG图片来说，不建议使用box-shadow，因为没法应用到path实体，这里建议使用filter属性：

.shadow_filter{      filter: drop-shadow(0px 0px 25px #116466);      }

这里通过第三个参数25px来控制发光的亮度，第四个参数可以改变颜色，暗色发光与亮色不发光的对比：

发光体与动画结合

除了静态的发光体，我们也可以让发光体“动”起来，首先建立发光体容器：

<div class="glowing">              <span style="--i:1;"></span>              <span style="--i:2;"></span>              <span style="--i:3;"></span>            </div>          <div class="glowing">              <span style="--i:1;"></span>              <span style="--i:2;"></span>              <span style="--i:3;"></span>            </div>          <div class="glowing">              <span style="--i:1;"></span>              <span style="--i:2;"></span>              <span style="--i:3;"></span>            </div>          <div class="glowing">              <span style="--i:1;"></span>              <span style="--i:2;"></span>              <span style="--i:3;"></span>            </div>

随后针对glowing容器添加动效：

.glowing {     position: relative;     min-width: 700px;     height: 550px;     margin: -150px;     transform-origin: right;     animation: colorChange 5s linear infinite;   }      .glowing:nth-child(even) {     transform-origin: left;   }      @keyframes colorChange {     0% {       filter: hue-rotate(0deg);       transform: rotate(0deg);     }     100% {       filter: hue-rotate(360deg);       transform: rotate(360deg);     }   }      .glowing span {     position: absolute;     top: calc(80px * var(--i));     left: calc(80px * var(--i));     bottom: calc(80px * var(--i));     right: calc(80px * var(--i));   }      .glowing span::before {     content: "";     position: absolute;     top: 50%;     left: -8px;     width: 15px;     height: 15px;     background: #f00;     border-radius: 50%;   }      .glowing span:nth-child(3n + 1)::before {     background: rgba(134,255,0,1);     box-shadow: 0 0 20px rgba(134,255,0,1),       0 0 40px rgba(134,255,0,1),       0 0 60px rgba(134,255,0,1),       0 0 80px rgba(134,255,0,1),       0 0 0 8px rgba(134,255,0,.1);   }      .glowing span:nth-child(3n + 2)::before {     background: rgba(255,214,0,1);     box-shadow: 0 0 20px rgba(255,214,0,1),       0 0 40px rgba(255,214,0,1),       0 0 60px rgba(255,214,0,1),       0 0 80px rgba(255,214,0,1),       0 0 0 8px rgba(255,214,0,.1);   }      .glowing span:nth-child(3n + 3)::before {     background: rgba(0,226,255,1);     box-shadow: 0 0 20px rgba(0,226,255,1),       0 0 40px rgba(0,226,255,1),       0 0 60px rgba(0,226,255,1),       0 0 80px rgba(0,226,255,1),       0 0 0 8px rgba(0,226,255,.1);   }      .glowing span:nth-child(3n + 1) {     animation: animate 10s alternate infinite;   }      .glowing span:nth-child(3n + 2) {     animation: animate-reverse 3s alternate infinite;   }      .glowing span:nth-child(3n + 3) {     animation: animate 8s alternate infinite;    }      @keyframes animate {     0% {       transform: rotate(180deg);     }     50% {       transform: rotate(0deg);     }     100% {       transform: rotate(360deg);     }   }      @keyframes animate-reverse {     0% {       transform: rotate(360deg);     }          50% {       transform: rotate(180deg);     }          100% {       transform: rotate(0deg);     }   }

这里通过colorChange方法来动态改变容器的位置和颜色，效果如下：

萤火虫特效

在移动发光体的基础上，我们可以继续精进，打造萤火虫的效果，首先创建元素容器：

<div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>   <div class="firefly"></div>

这里容器越多，萤火虫越密集。

随后将容器样式改成fixed定位，让萤火虫跟随窗口移动：

firefly {     position: fixed;     left: 50%;     top: 50%;     width: 0.4vw;     height: 0.4vw;     margin: -0.2vw 0 0 9.8vw;     animation: ease 200s alternate infinite;     pointer-events: none;   }   .firefly::before, .firefly::after {     content: "";     position: absolute;     width: 100%;     height: 100%;     border-radius: 50%;     transform-origin: -10vw;   }   .firefly::before {     background: black;     opacity: 0.4;     animation: drift ease alternate infinite;   }   .firefly::after {     background: white;     opacity: 0;     box-shadow: 0 0 0vw 0vw yellow;     animation: drift ease alternate infinite, flash ease infinite;   }      .firefly:nth-child(1) {     animation-name: move1;   }   .firefly:nth-child(1)::before {     animation-duration: 10s;   }   .firefly:nth-child(1)::after {     animation-duration: 10s, 10206ms;     animation-delay: 0ms, 8110ms;   }

随后编写移动动画，让萤火虫进行不规则运动：

@keyframes move1 {     0% {       transform: translateX(-2vw) translateY(49vh) scale(0.6);     }     4.7619047619% {       transform: translateX(-21vw) translateY(-20vh) scale(0.88);     }     9.5238095238% {       transform: translateX(19vw) translateY(-20vh) scale(0.95);

    }     28.5714285714% {       transform: translateX(-22vw) translateY(29vh) scale(0.89);     }     33.3333333333% {       transform: translateX(26vw) translateY(7vh) scale(0.61);     }     38.0952380952% {       transform: translateX(45vw) translateY(9vh) scale(0.73);

    }     71.4285714286% {       transform: translateX(-3vw) translateY(-21vh) scale(0.74);     }     76.1904761905% {       transform: translateX(16vw) translateY(2vh) scale(0.9);     }     80.9523809524% {       transform: translateX(20vw) translateY(46vh) scale(0.77);     }     85.7142857143% {       transform: translateX(12vw) translateY(-23vh) scale(0.8);     }     90.4761904762% {       transform: translateX(8vw) translateY(-24vh) scale(0.73);     }     95.2380952381% {       transform: translateX(-35vw) translateY(-11vh) scale(0.47);

  }   .firefly:nth-child(2)::after {     animation-duration: 10s, 6664ms;     animation-delay: 0ms, 4112ms;   }      @keyframes move2 {     0% {       transform: translateX(-3vw) translateY(13vh) scale(1);     }     4% {       transform: translateX(0vw) translateY(-4vh) scale(0.79);     }     8% {       transform: translateX(-1vw) translateY(-41vh) scale(0.84);     }     12% {       transform: translateX(-43vw) translateY(3vh) scale(0.73);     }     16% {       transform: translateX(17vw) translateY(-39vh) scale(0.26);     }     20% {       transform: translateX(9vw) translateY(34vh) scale(0.57);     }     24% {       transform: translateX(25vw) translateY(-44vh) scale(0.42);

这里每个萤火虫的移动轨迹都是单独定制的，也可以使用Sass进行复用，效果如下：

暗夜发光,独自闪耀,盘点网页暗黑模式(DarkMode)下的特效和动效,CSS3实现

暗夜流星

和萤火虫特效不同，暗夜流星顾名思义，就是璀璨的流星划过长夜，给人以转瞬即逝的美丽，首先还是设置容器元素：

<div class="star"></div>   <div class="meteor-1"></div>   <div class="meteor-2"></div>   <div class="meteor-3"></div>   <div class="meteor-4"></div>   <div class="meteor-5"></div>   <div class="meteor-6"></div>   <div class="meteor-7"></div>   <div class="meteor-8"></div>   <div class="meteor-9"></div>   <div class="meteor-10"></div>   <div class="meteor-11"></div>   <div class="meteor-12"></div>   <div class="meteor-13"></div>   <div class="meteor-14"></div>   <div class="meteor-15"></div>

这里除了流星容器，我们还使用stat容器设置繁星满天的效果，和流星特效交相辉映，相得益彰。

随后设置CSS样式:
