太阳升起和落下(长文警告)

今天分享一个太阳升起落下的动画场景。

有朋友问我为什么只发代码不做说明，今天我们尝试下对代码进行注解说明一下。

首先这个场景大致的可拆分为4个部分：太阳/月亮，右下角的按钮，天上的云和最显眼的建筑。

我们先做一个按钮，它可以控制整个场景的切换，像下面这样我们定义一个按钮和一个标签，：

<input type="checkbox" id="day-night"><label for="day-night"></label>

写了这个按钮就会出现么，答案是：NO。我们还需要一点点小小的CSS代码：

/* 按钮 */input {display: none; }/*按钮动画效果切换*/input#day-night:checked ~ .content .clouds {top: -10vh;transition: all 3s var(--cbz) 0s;opacity: 1;filter: drop-shadow(1vmin -1vmin 1vmin #fff) drop-shadow(-1vmin 1vmin 5vmin #fff) drop-shadow(20vmin 5vmin 5vmin #fff) drop-shadow(-10vmin -1vmin 3vmin #fff);}input#day-night:checked ~ .content {transition: --glass 3s;--glass: 200deg;}/*标签设置*/label {position: absolute;right: 3vmin;bottom: 3vmin;width: 13vmin;height: 5vmin;background: #0008;border-bottom: 1px solid #fff8;border-top: 1px solid #000;border-radius: 4vmin;cursor: pointer;z-index: 3;}/*标签伪元素before*/label:before {content: "";position: absolute;width: 12vmin;height: 4vmin;background: radial-gradient(circle at 50% 48%, #ffbf00 calc(2vmin - 1px), #fff0 2vmin), radial-gradient(circle at 90% 42%, #fff0 2.5vmin, #e6e6e6 calc(2.5vmin + 1px));border-radius: 2vmin;left: 0.6vmin;top: 0.325vmin;transition: all 0.4s ease 1s;background-repeat: no-repeat;background-size: 4.25vmin 4.25vmin, 4.15vmin 4.15vmin;background-position: 7.85vmin 0, 0vmin 0vmin;}/*标签伪元素after*/label:after {content: "";position: absolute;width: 6vmin;height: 6vmin;border-radius: 100%;left: -0.95vmin;top: -1.1vmin;transition: all 1s var(--cbz) 0s;border: 0.5vmin solid #fffc;box-shadow: 0 0 1vmin 0 #fffc, 0 0 1vmin 0 #fffc inset;}/*选择器，用来设定点击后的样式改变*/input#day-night:checked + label:after {border-color: #ffc71e;box-shadow: 0 0 1vmin 0.25vmin #ffc71e, 0 0 1vmin 0.25vmin #ffc71e inset;}input#day-night:checked + label:after {left: 6.95vmin;transition: all 1s var(--cbz) 0s;}

当然还有全局设置不能忘记：

@property --glass {syntax: '<angle>';inherits: false;initial-value: 337deg;}* {transform-style: preserve-3d;box-sizing: border-box;}body {margin: 0;padding: 0;width: 100vw;height: 100vh;overflow: hidden;display: flex;align-items: flex-end;justify-content: center;--cbz: cubic-bezier(0.68, -0.55, 0.27, 1.55);}

这样一套操作下来，我们就可以得到右下角的按钮，这个时候整体的页面只有下面的按钮：

这样看起来不但丑而且很单调，光秃秃的。不过不要紧，我们接着给它填上背景：

<div class="content"></div>

同样加上一点点CSS代码：

.content {--frame: #070b32;--bush: #181b38;--dot1: radial-gradient(circle at 50% 50%, var(--bush) 0 0.25vmin, #fff0 calc(0.25vmin + 1px) 100%);--dot2: radial-gradient(circle at 50% 50%, var(--bush) 0 0.5vmin, #fff0 calc(0.5vmin + 1px) 100%);--dot3: radial-gradient(circle at 50% 50%, var(--bush) 0 1.15vmin, #fff0 calc(1.15vmin + 1px) 100%);--glass: 337deg;--luz1: hsl(var(--glass) 60% 50% / 60%);--luz2: hsl(var(--glass) 54% 32%);--luz3: hsl(var(--glass) 54% 25%);transition: --glass 3s;width: 80vmin;height: 100vh;display: flex;align-items: flex-end;justify-content: center;animation: start-glass 3s var(--cbz) 0s 1;}.content:before {content: "";position: absolute;width: 100vw;height: 100%;background: linear-gradient(180deg, #000, #080212, #341c5e, #50587e, #0079d9, #39a7ff, #70c6ed 100%);background-repeat: no-repeat;background-size: 100% 300%;background-position: 0% 10%;transform: translateZ(-100vmin);transition: all 3s var(--cbz) 0s;animation: start-bg 3s var(--cbz) 0s 1;}.content:after {content: "";position: absolute;width: 100vw;height: 200%;--s1: radial-gradient(0.1vmin 0.1vmin at 50% 50%, #ffffff, #fff0);--s2: radial-gradient(0.2vmin 0.2vmin at 50% 50%, #ffffff, #fff0);background-image: var(--s1),var(--s1), var(--s1),var(--s2), var(--s2),var(--s1), var(--s2),var(--s1), var(--s2),var(--s1), var(--s2),var(--s1), var(--s2),var(--s1), var(--s1),var(--s2), var(--s2),var(--s1), var(--s1),var(--s2), var(--s1),var(--s1);background-repeat: repeat-x;background-size: 26% 25%, 43.33% 33.33%, 50% 80%, 20% 20%, 33.33% 75.33%, 26% 73%, 39.33% 22%, 33.33% 26%, 31% 32%, 14.33% 35.33%, 18.33% 62.33%, 39.33% 86.33%, 29.33% 69%, 12.33% 30.33%, 29.33% 41.33%, 22.33% 46.33%, 35.33% 27.33%, 22.33% 39.33%, 20.33% 44.33%, 33.33% 56.33%;filter: drop-shadow(0px 0px 2px #fff) drop-shadow(0px 0px 5px #fff);background-position: -8% -10%;transform: translateZ(-100vmin);transition: all 3s var(--cbz) 0s;top: -16vmin;animation: start-stars 3s var(--cbz) 0s 1;}

这里我们给了两个不同的界面，黑夜和白天。如果有同学将这段代码沾进编辑器会发现出现的只有黑夜，点烂了切换按钮也不会变成白天。这是背景这会和按钮并没有关联起来，添加下面代码将它们关联。

input#day-night:checked ~ .content:before {background-position: 0% 90%;transition: all 3s var(--cbz) 0s;}input#day-night:checked ~ .content:after {top: -100%;transition: all 3s var(--cbz) 0s;}

这个时候整体看起来就好多了。

看起来还是有点诡异，明晃晃的天上竟然没有太阳！我的天，这是搞神嘛！

别急，太阳会来的，月亮也会~

搞一个太阳和月亮和简简单单的animation动画:

<div class="moon-sun"></div>

再加上css代码：

.moon-sun {position: absolute;width: 18vmin;height: 18vmin;bottom: 70vmin;margin-left: 90vmin;border-radius: 100%;background-repeat: no-repeat;animation: change-sm 3s var(--cbz) 0s 1;animation-fill-mode: forwards;background: radial-gradient(circle at 45% 55%, #fff -13%, yellow 35%, orange 90%, #fff0 90%);box-shadow: 0 0 6em 3em #ff9800, 0 0 8em 0 #ff9800 inset, 0 0 20px 5px #fdfdfd;--moon:radial-gradient( circle at 26% 71%, #ffffff 8%, #fff0 12% ),radial-gradient( circle at 23% 75%, #ccc 0% 1%, #fff0 10% ),radial-gradient( circle at 14% 42%, #fdfdfd 7%, #fff0 11% ),radial-gradient( circle at 12% 45%, #ccc 0%, #fff0 7% ),radial-gradient( circle at 23% 57%, #f9f9f9 2%, #fff0 6% ),radial-gradient( circle at 22% 58%, #ccc -2%, #fff0 4% ),radial-gradient(circle at 83% 25%, #fff0 10vmin, #fff calc(10vmin + 1px));filter: drop-shadow(0px 1px 6vmin #6493a9) drop-shadow(0px 1px 6vmin #fdfdfd);}input#day-night:checked ~ .content .moon-sun {animation: change-ms 3s var(--cbz) 0s 1 reverse;animation-fill-mode: forwards;}

这样搞了之后还是有点奇怪，为什么呢？因为…

嗯,仔细看一下代码,发现缺少两个月亮的关键帧,加上~

/*月亮*/@keyframes change-sm {0% {bottom: 70vmin; }45%, 55% {bottom: -35vmin; }49% {background: #ffeb3b; filter: drop-shadow(0px 1px 6vmin #ff9800) drop-shadow(0px 1px 6vmin #fdfdfd); }50% {background: var(--moon); }100% {bottom: 70vmin; background: var(--moon);filter: drop-shadow(0px 1px 6vmin #6493a9) drop-shadow(0px 1px 6vmin #fdfdfd); box-shadow: none; }}/*月亮落下*/@keyframes change-ms {0% {bottom: 70vmin; }45%, 55% {bottom: -35vmin; }49% {background: #ffeb3b; filter: drop-shadow(0px 1px 6vmin #ff9800) drop-shadow(0px 1px 6vmin #fdfdfd); }50% {background: var(--moon); }100% {bottom: 70vmin; background: var(--moon);filter: drop-shadow(0px 1px 6vmin #6493a9) drop-shadow(0px 1px 6vmin #fdfdfd); box-shadow: none; }}

月亮出来了,世界得救了~~

下来,我们再搞点云来~

<div class="clouds"></div>

.clouds {position: absolute;top: 75vh;width: 100vw;height: 100%;background: radial-gradient(ellipse at 10% 23%, #fff1 4vmin, #fff0 15vmin),radial-gradient(ellipse at 0% 15%, #fff1 4vmin, #fff0 8vmin), radial-gradient(circle at 6% 17%, #fff1 4vmin, #fff0 8vmin), radial-gradient(ellipse at 4% 16%, #fff1 1vmin, #fff0 5vmin), radial-gradient(circle at 9% 16%, #fff1 1vmin, #fff0 5vmin), radial-gradient(ellipse at 12% 18%, #fff1 1vmin, #fff0 5vmin), radial-gradient(circle at 17% 19%, #fff1 2vmin, #fff0 6vmin), radial-gradient(ellipse at 13% 13%, #fff1 1vmin, #fff0 6vmin), radial-gradient(ellipse at 22% 20%, #fff1 2vmin, #fff0 8vmin), radial-gradient(circle at 4% 22%, #fff1 0vmin, #fff0 4vmin), radial-gradient(circle at 7% 24%, #fff1 0vmin, #fff0 4vmin), radial-gradient(ellipse at 10% 22%, #fff1 0vmin, #fff0 4vmin), radial-gradient(circle at 30% 19%, #fff2 0vmin, #fff0 13vmin), radial-gradient(circle at 26% 13%, #fff1 0vmin, #fff0 4vmin), radial-gradient(circle at 33% 15%, #fff1 -3vmin, #fff0 7vmin), radial-gradient(circle at 45% 19%, #fff1 4vmin, #fff0 14vmin), radial-gradient(circle at 38% 20%, #fff1 -3vmin, #fff0 7vmin), radial-gradient(circle at 52% 20%, #fff1 0vmin, #fff0 6vmin), radial-gradient(circle at 56% 15%, #fff1 0vmin, #fff0 7vmin), radial-gradient(circle at 58% 18%, #fff1 0vmin, #fff0 7vmin), radial-gradient(circle at 41% 26%, #fff1 2vmin, #fff0 8vmin), radial-gradient(circle at 60% 15%, #fff1 0vmin, #fff0 7vmin), radial-gradient(circle at 63% 12%, #fff1 0vmin, #fff0 7vmin), radial-gradient(circle at 63% 21%, #fff1 4vmin, #fff0 15vmin), radial-gradient(circle at 60% 25%, #fff1 2vmin, #fff0 7vmin), radial-gradient(ellipse at 63% 20%, #fff1 0vmin, #fff0 7vmin), radial-gradient(circle at 71% 25%, #fff1 2vmin, #fff0 9vmin), radial-gradient(ellipse at 84% 22%, #fff1 -1vmin, #fff0 8vmin), radial-gradient(ellipse at 78% 25%, #fff1 -1vmin, #fff0 10vmin), radial-gradient(ellipse at 90% 18%, #fff1 -1vmin, #fff0 10vmin), radial-gradient(ellipse at 93% 17%, #fff1 2vmin, #fff0 11vmin), radial-gradient(circle at 79% 17%, #fff1 -3vmin, #fff0 7vmin), radial-gradient(ellipse at 73% 12%, #fff1 -3vmin, #fff0 6vmin), radial-gradient(ellipse at 68% 15%, #fff1 -2vmin, #fff0 9vmin), radial-gradient(ellipse at 95% 25%, #fff1 -2vmin, #fff0 9vmin), radial-gradient(ellipse at 98% 26%, #fff1 -2vmin, #fff0 9vmin), radial-gradient(ellipse at 90% 23%, #fff1 -2vmin, #fff0 9vmin);transform: translateZ(-100vmin);transition: all 3s var(--cbz) 0s;opacity: 0.6;}.clouds span {opacity: 0;}

看看效果:

完美,下来就差房子了.房子比较复杂一些,我们先写一个形状出来

<div class="cuboid floor one"><div class="side"></div><div class="side"></div><div class="side"></div><div class="side"></div><div class="side"></div><div class="side"></div></div>

.cuboid {--width: 20;--depth: 20;--height: 20;--hue: 235;--sat: 25%;height: calc(var(--height) * 1vmin);width: calc(var(--width) * 1vmin);position: absolute;transform: rotateY(-8deg) rotateX(5deg) translateZ(-24vmin);}.cuboid .side {position: absolute;top: 50%;left: 50%;height: 100%;width: 100%;border-radius: 1px;}.cuboid .side:nth-of-type(1) {--sat: 40%;transform: translate3d(-50%, -50%, calc(var(--depth) * 0.5vmin));background: hsl(var(--hue), var(--sat), 18%);}.cuboid .side:nth-of-type(2) {transform: translate3d(-50%, -50%, calc(var(--depth) * -0.5vmin))rotateY(180deg);background: hsl(var(--hue), var(--sat), 35%);}.cuboid .side:nth-of-type(3) {width: calc(var(--depth) * 1vmin);transform: translate(-50%, -50%) rotateY(90deg)translate3d(0, 0, calc(var(--width) * 0.5vmin));background: hsl(var(--hue), var(--sat), 35%);}.cuboid .side:nth-of-type(4) {width: calc(var(--depth) * 1vmin);transform: translate(-50%, -50%) rotateY(-90deg)translate3d(0, 0, calc(var(--width) * 0.5vmin));background: hsl(var(--hue), var(--sat), 40%);}.cuboid .side:nth-of-type(5) {--sat: 60%;height: calc(var(--depth) * 1vmin);transform: translate(-50%, -50%) rotateX(90deg)translate3d(0, 0, calc(var(--height) * 0.5vmin));background: hsl(var(--hue), var(--sat), 10%);}.cuboid .side:nth-of-type(6) {--sat: 60%;height: calc(var(--depth) * 1vmin);transform: translate(-50%, -50%) rotateX(-90deg)translate3d(0, 0, calc(var(--height) * 0.5vmin));background: hsl(var(--hue), var(--sat), 10%);}

看看效果:

下来我们给它加上屋顶和窗子:

<div class="cuboid roof one"><div class="side"><i class="cactus"></i></div><div class="side"></div><div class="side"></div><div class="side"></div><div class="side"></div><div class="side"></div></div>

在小小的修饰一下:

加上一个仙人掌:

i.cactus {background: var(--bush);width: 0.85vmin;height: 2vmin;position: absolute;bottom: 3vmin;left: 3px;border-radius: 100% 100% 10% 45%;transform: rotate(-2deg);}i.cactus:before {content: "";position: absolute;background: var(--bush);width: 0.75vmin;height: 2vmin;bottom: 1.4vmin;left: -0.35vmin;border-radius: 100%;}i.cactus:after {content: "";position: absolute;background: var(--bush);width: 0.5vmin;height: 1.5vmin;bottom: 3vmin;left: 0.075vmin;border-radius: 100%;box-shadow: -0.6vmin 0.2vmin 0 -0.075vmin var(--bush), 0.4vmin 1.5vmin 0 -0.075vmin var(--bush);}

加上百叶窗,让它变得像个房子:

.floor .side:nth-of-type(1):before, .floor .side:nth-of-type(1):after,.floor .side:nth-of-type(3):before, .floor .side:nth-of-type(3):after {position: absolute;content: "";width: 40%;height: 100%;left: 20%;background: repeating-linear-gradient(180deg, #101010, transparent), repeating-linear-gradient(90deg, #383e70 0 calc(100% - 0.25vmin), var(--frame) calc(100% - 0.25vmin) 100%);background-size: 100% 0.365vmin, 8vmin 100%;}.floor .side:nth-of-type(1):after {width: 20%;left: 80.25%;}

再加上地板和玻璃窗子:

.floor {--width: 40;--depth: 89;--height: 8;bottom: -5vmin;left: 16vmin;--lines-front: repeating-linear-gradient(90deg, var(--luz1) 0% calc(100% - 0.275vmin), var(--frame) calc(100% - 0.275vmin) 100%);--lines-side: repeating-linear-gradient(90deg, var(--luz1) 0% calc(100% - 1.5vmin), var(--frame) calc(100% - 1.5vmin) 100%);}.floor .side {border: 3px solid var(--frame); }.floor.two {bottom: 5vmin; }.floor.three {bottom: 15vmin; }.floor.four {bottom: 25vmin; }.floor.five {bottom: 35vmin; }.floor.six {bottom: 45vmin; }.floor.seven {bottom: 55vmin; }.floor.eight {bottom: 65vmin; }.floor .side:nth-of-type(1) {background:conic-gradient(from 116deg at 0 0, var(--luz2) 0 25%, #fff0 0 100%),linear-gradient(31deg, #fff0 60%, var(--luz2) 61%),linear-gradient(31deg, #fff0 20%, var(--luz2) 21%),linear-gradient(31deg, var(--luz1) 65%, var(--luz2) 21%),linear-gradient(90deg, var(--luz1) 19.5%, #fff0 19.5% 20%, var(--luz1) 20.5% 39.5%, #fff0 40% 61%, var(--luz3) 61% 80.25%, #fff0 80% 81%, var(--luz2) 81% 100%);background-size: 2.5% 51%, 19.5% 100%, 19.5% 100%, 19.5% 100%, 100% 100%;background-repeat: no-repeat;background-position: 79.75% 100%, 0 0, 25% 0, 75.4% 0, 0 0;}.floor .side:nth-of-type(3) {background: var(--lines-side), hsl(var(--hue) var(--sat) 75% / 0.5);background-size: 35.45% 100%;}.floor .side:nth-of-type(4) {background: var(--lines-side), hsl(var(--hue) var(--sat) 40% / 0.5);background-size: 35.45% 100%;}span {background: linear-gradient(32deg, #fff0 17%, var(--luz2) 19%), var(--luz1);position: absolute;width: 20%;height: 100%;left: 20%;}

这个时候它是这样的:

已经有点样子,下面我们继续往上盖和加些小物件进去,花,空调,猫,人,屋子里的灯光等就可以.
