    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);  
  }

    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:

    .star {  
  width: 1px;  
  height: 1px;  
  background: transparent;  
  box-shadow: 678px 47px #fff, 1218px 895px #fff, 808px 793px #fff, 1059px 585px #fff, 1657px 258px #fff, 1671px 34px #fff, 758px 990px #fff, 290px 246px #fff, 1783px 218px #fff, 968px 883px #fff,

    这里stat容器通过上文的box-shadow属性设置发光点，随后15颗流星容器通过meteor方法效果划过夜空：

    身前是万家灯火，身后是繁星闪烁，绝了。

    结语

    白天不懂夜的黑，夜色朦胧最迷离，黑夜给了我们黑色的眼睛，我们却用它来寻找发光的特效，暗夜发光，独自闪耀，摄人魂魄，心驰神往，别有一番风味。
