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);

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:
