太阳升起和落下(长文警告)

简介: 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。

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:
2.png

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;
