暗夜發光,獨自閃耀,盤點網頁暗黑模式(DarkMode)下的特效和動效,CSS3實現
2023-03-23 09:01:21
眾所周知，網頁的暗黑模式可以減少螢幕反射和藍光輻射，減少眼睛的疲勞感，特別是在夜間使用時更為明顯。其實暗黑模式也給霓虹燈效應（Neon Effect）提供了發揮的環境。
霓虹燈效應是一種視覺效果，其特點是在深色背景上使用鮮豔的顏色來產生強烈的視覺衝擊。這種效應通常用於設計海報、廣告、標誌和網頁等。霓虹燈效應的作用在於吸引人們的注意力和增強品牌形象的辨識度，因為這種效果讓人印象深刻且易於記憶，本次我們盤點適合暗色模式的網頁特效，還是喜歡，暗夜的你。
發光特效
暗黑模式下最炫酷的效果無外乎發光，基本上頁面元素的發光需要依賴box-shadow屬性：
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) */
}
這裡使用多個陰影值來建立分層效果。您可以用逗號分隔多個陰影值，它們將疊加在彼此上面。
但是這種效果比較單調，box-shadow屬性只會保持所在的元素的形狀上發光，如果我們想讓一個元素的發光效果比較有層次感，那麼就需要border-radius屬性的配合。
我們可以通過給出多組值（用逗號分隔）來在一個元素上堆疊多個發光效果。發光效果將首先堆疊在頂部，最後一個堆疊在底部：
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 */
}
說白了就是漸進的光暈效果，最內層往最內層逐漸減淡：
配合動畫特效，比如animation屬性：
.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;
}
隨後結合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;
}
我們就可以營造出這種「冷燈看劍，劍上幾番功名」的特效：
對於SVG圖片來說，不建議使用box-shadow，因為沒法應用到path實體，這裡建議使用filter屬性：
.shadow_filter{
filter: drop-shadow(0px 0px 25px #116466);
}
這裡通過第三個引數25px來控制發光的亮度，第四個引數可以改變顏色，暗色發光與亮色不發光的對比：
發光體與動畫結合
除了靜態的發光體，我們也可以讓發光體「動」起來，首先建立發光體容器：
<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>
隨後針對glowing容器新增動效：
.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);
}
}
這裡通過colorChange方法來動態改變容器的位置和顏色，效果如下：
螢火蟲特效
在移動發光體的基礎上，我們可以繼續精進，打造螢火蟲的效果，首先建立元素容器：
<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>
這裡容器越多，螢火蟲越密集。
隨後將容器樣式改成fixed定位，讓螢火蟲跟隨視窗移動：
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;
}
隨後編寫移動動畫，讓螢火蟲進行不規則運動：
@keyframes move1 {

transform: translateX(-2vw) translateY(49vh) scale(0.6);

這裡每個螢火蟲的移動軌跡都是單獨客製化的，也可以使用Sass進行復用，效果如下：
暗夜流星
和螢火蟲特效不同，暗夜流星顧名思義，就是璀璨的流星劃過長夜，給人以轉瞬即逝的美麗，首先還是設定容器元素：
<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>
這裡除了流星容器，我們還使用stat容器設定繁星滿天的效果，和流星特效交相輝映，相得益彰。
隨後設定CSS樣式:
