纯CSS3实现的一些酷炫效果

  之前在网上看到一些用纯CSS3实现的酷炫效果,以为实现起来比较困难,于是想看看具体是怎么实现的。

一、笑脸猫动画

实现效果如下:

这个实现起来确实比较麻烦,很多地方需要花时间,有耐心地调整。

1.先看下页面结构:

<body>
  <div class="container">
    <!---->
    <div class="face">
      <!-- 头发 -->
      <div class="hair">
        <div></div>
      </div>
      <!-- 眼睛 -->
      <div class="eye-wrap">
        <div class="eye left">
          <div class="eye-circle">
            <div class="eye-core"></div>
          </div>
          <div class="eye-bottom"></div>
          <div class="eye-red"></div>
        </div>
        <div class="eye right">
          <div class="eye-circle">
            <div class="eye-core"></div>
          </div>
          <div class="eye-bottom"></div>
          <div class="eye-red"></div>
        </div>
      </div>
      <!-- 鼻子 -->
      <div class="nose">
      </div>
      <!-- 嘴巴 -->
      <div class="mouth-wrap">
        <!-- <div class="mouth-top"></div> -->
        <div class="mouth left"></div>
        <div class="mouth right"></div>
      </div>
      <!-- 胡子 -->
      <div class="mustache-wrap">
        <div class="mustache left">
          <div></div>
          <div></div>
          <div></div>
          <div></div>
          <div></div>
        </div>
        <div class="mustache right">
          <div></div>
          <div></div>
          <div></div>
          <div></div>
          <div></div>
        </div>
      </div>
    </div>
    <!-- 耳朵 -->
    <div class="ear-wrap">
      <div class="ear left"> </div>
      <div class="ear right"> </div>
    </div>
  </div>
</body>

2.再看css部分

1.先看脸部face:

.face {
  /* top: 100px; */
  left: 50%;
  top: 50%;
  position: absolute;
  width: 400px;
  height: 340px;
  margin-left: -200px;
  margin-top: -170px;
  border-radius: 50% 50% 35% 35%;
  border: 2px solid #000;
  z-index: 10;
  background: #f3f3f3;
  overflow: hidden;
}

主要是要画出椭圆形,width和height设置的值要注意,脸比较宽。然后关键就是border-radius的设置了:

border-radius全部设置为0时,就是一个长方形,然后把它的四个角对应的设置下,就可以出现我们想要的效果。

2.接下来看耳朵的设置:

耳朵看起来其实也是一个椭圆,通过设置border-radius,调出想要的效果。不过需要被遮住一部分,所以在HTML结构中,我把它放在face的外面了。

/* 耳朵 */
.ear-wrap {
  position: absolute;
  width: 400px;
  top: 100px;
  left: 50%;
  margin-left: -200px;
}
.ear {
  width: 160px;
  height: 200px;
  position: absolute;
  top: -22px;
  left: 0;
  border: 2px solid #000;
  background: #f3f3f3;
  transform: rotate(-15deg);
  -ms-transform: rotate(-15deg);
  -moz-transform: rotate(-15deg);
  -webkit-transform: rotate(-15deg);
  -o-transform: rotate(-15deg);
  border-radius: 4% 80% 0% 50%;
  transition: all 1s;
}
.ear-wrap .right {
  left: auto;
  right: 0;
  border-radius: 80% 4% 50% 0%;
  transform: rotate(15deg);
  -ms-transform: rotate(15deg);
  -moz-transform: rotate(15deg);
  -webkit-transform: rotate(15deg);
  -o-transform: rotate(15deg);
}
View Code

这是竖起来的耳朵,通过 transform:rotate(15deg); 旋转一点,耳朵就塌下来了。

3.然后是头发:

 有了上述的实践,知道头发也好弄了,还是椭圆

/* 头发 */
.hair {
  position: absolute;
  width: 180px;
  height: 160px;
  left: 50%;
  margin-left: -90px;
  background: #8d8d8d;
  overflow: hidden;
  border-radius: 0 0 50% 50%;
}
.hair div {
  width: 90px;
  height: 160px;
  background: #f0ac6b;
}
View Code

另外一个颜色,只需要在里面加一个子div,然后给不同的颜色就ok。

4.再来看眼睛:

眼睛比较复杂,拆分四个小部件,眼眶,眼珠,下眼线,眼红(笑起来露出的表情),对应的效果设置为:

/* 眼睛 */
.eye-wrap {
  position: absolute;
  width: 300px;
  height: 60px;
  top: 200px;
  left: 50%;
  margin-left: -150px;
  overflow: hidden;
}
.eye-wrap .eye {
  height: 100px;
  width: 100px;
  position: absolute;
}
.eye-wrap .eye-circle {
  width: 100px;
  height: 100px;
  border: 2px solid #000;
  overflow: hidden;
  position: absolute;
  border-radius: 50%;
  box-sizing: border-box;
}
.eye-wrap .eye-core {
  height: 100px;
  width: 30px;
  /* margin: 0 auto; */
  background: #000;
  position: absolute;
  left: 50%;
  margin-left: -15px;
  transition: all 1s;
}
.eye-wrap .eye-bottom {
  height: 50px;
  width: 160px;
  border-radius: 50%;
  position: absolute;
  /* background: #000; */
  margin-top: 50px;
  border-top: 2px solid #000;
  left: -30px;
  background: #f6f7f2;
  transition: all 1s;
}
.eye-wrap .right {
  left: auto;
  right: 0px;
}
.eye-red {
  position: absolute;
  height: 28px;
  width: 70px;
  background: red;
  top: 34px;
  /*top: 64px;*/
  left: 18px;
  border-radius: 50% 50% 50% 50%;
  background-image: -moz-radial-gradient( 50% 50%, rgba(253,214,240,0.8) 0%, rgba(253,224,244,0.8) 66%, rgba(253,234,247,0.8) 100%);
  background-image: -webkit-radial-gradient( 50% 50%, rgba(253,214,240,0.8) 0%, rgba(253,224,244,0.8) 66%, rgba(253,234,247,0.8) 100%);
  background-image: -ms-radial-gradient( 50% 50%, rgba(253,214,240,0.8) 0%, rgba(253,224,244,0.8) 66%, rgba(253,234,247,0.8) 100%);
  opacity: 0.0;
  /* transition: all 1.5s; */
  transition: all 0.1s ease-in 0.2s;
}
View Code

注意左右两只眼睛效果大致是一样,只是位置不一样,这是我们只需要设置右边的 right: 0px; 就可以(因为设置了position: absolute)

5.鼻子:

/* 鼻子 */
.nose {
  width: 30px;
  height: 10px;
  /* background: #000; */
  border-bottom: 8px solid #000;
  border-radius: 0% 0% 50% 50%;
  top: 250px;
  left: 50%;
  margin-left: -15px;
  position: absolute;
}

这里特别注意,height:10px; border-bottom: 8px solid #000;的设置,我本来想只用height:10px;然后设置border-radius,可是效果却长这样:

没有半圆的效果,是高度设置不够?变成18px,这货长这样,也不对,所以就加上border-bottom

6.嘴巴:

/* 嘴巴 */
.mouth-wrap {
  position: absolute;
  top: 268px;
  width: 100px;
  left: 50%;
  margin-left: -50px;
  height: 20px;
  overflow: hidden;
}
.mouth {
  width: 50px;
  height: 40px;
  border-bottom: 4px solid #000;
  border-right: 4px solid #000;
  border-radius: 0% 40% 50% 20%;
  margin-top: -26px;
  position: absolute;
  left: 0;
  transition: all 1s;
}
.mouth-wrap .right {
   border-bottom: 4px solid #000;
  border-right: none;
  border-left: 4px solid #000;
  border-radius: 40% 0% 20% 50%;
  position: absolute;
  left: auto;
  right: 0;
}
View Code

算是比较简单,设置border-bottom,border-left或border-right就可以。嘴巴上翘的效果是改变其border-radius值

7.两边的胡子:

/* 胡子 */
.mustache-wrap {
    height: 80px;
    width: 380px;
    position: absolute;
    top: 190px;
    z-index: 20;
    left: 50%;
    margin-left: -190px;
}
.mustache > div:first-child {
    width: 30px;
    height: 10px;
    border-top: 6px #E53941 solid;
    border-radius: 30% 50% 20% 50%;
    transform: rotate(25deg);
    -ms-transform: rotate(25deg);
    -moz-transform: rotate(25deg);
    -webkit-transform: rotate(25deg);
    -o-transform: rotate(25deg);
    margin-left: 20px;
}
.mustache > div:nth-child(2) {
    width: 20px;
    height: 6px;
    background-color: #E53941;
    border-radius: 50% 50% 50% 50%;
    transform: rotate(25deg);
    -ms-transform: rotate(25deg);
    -moz-transform: rotate(25deg);
    -webkit-transform: rotate(25deg);
    -o-transform: rotate(25deg);
    margin-left: 20px;
}
.mustache > div:nth-child(3) {
    /*margin-top:10px;*/
    width: 32px;
    height: 10px;
    border-bottom: 4px #E53941 solid;
    border-radius: 30% 0% 50% 30%;
    transform: rotate(25deg);
    -ms-transform: rotate(25deg);
    -moz-transform: rotate(25deg);
    -webkit-transform: rotate(25deg);
    -o-transform: rotate(25deg);
    margin-left: 8px;
}
.mustache > div:nth-child(4) {
    margin-top: 20px;
    width: 26px;
    height: 20px;
    border-bottom: 4px #E53941 solid;
    border-radius: 30% 0% 50% 30%;
    transform: rotate(30deg);
    -ms-transform: rotate(30deg);
    -moz-transform: rotate(30deg);
    -webkit-transform: rotate(30deg);
    -o-transform: rotate(30deg);
    margin-left: 28px;
}
.mustache > div:last-child {
    width: 22px;
    height: 10px;
    border-bottom: 3px #E53941 solid;
    border-radius: 0% 0% 50% 50%;
    transform: rotate(-15deg);
    -ms-transform: rotate(-15deg);
    -moz-transform: rotate(-15deg);
    -webkit-transform: rotate(-15deg);
    -o-transform: rotate(-15deg);
    margin-left: 40px;
    margin-top: -8px;
}
/*右边胡子*/
.mustache-wrap .right {
    transform: rotateY(180deg);
    -webkit-transform: rotateY(180deg); /* Safari 和 Chrome */
    -moz-transform: rotateY(180deg); /* Firefox */
    margin-top: -85px;
}
View Code

虽然比较麻烦,不过也算是简单的图形,只需要把height,width,border-top,border-radius,transform: rotate这些值设置恰当就好。

8.鼠标hover样式:

/*鼠标hover样式*/
.container:hover .ear-wrap > div:first-child {
    /* left: -10px; */
    transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -webkit-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    border-radius: 4% 80% 0% 60%;
    transition: all 1s;
     /*transition: transform 1s,left 1s;*/
}

.container:hover .ear-wrap > div:last-child {
    /* right: -10px; */
    transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -webkit-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    border-radius: 80% 4% 60% 0%;
    transition: all 1s;
    /*transition: transform 1s,right 1s;*/
}
.container:hover .eye-bottom {
  margin-top: 30px;
  transition: all 1s;
}
.container:hover .eye-red {
  opacity: 1;
  transition: all 2.5s;
}
.container:hover .mouth {
  border-radius: 50%;
  transition: all 1s;
}
.container:hover .eye-core {
  width: 40px;
  margin-left: -20px;
  transition: all 1s;
}
View Code

耳朵,嘴巴,眼睛等地方需要修改transform,border-radius,width等值的属性。

1.3维空间图

电脑屏幕中心为原点,横向为X轴,纵向为Y轴,人脸的方向为Z轴;

translate(x,y)、translateX(x)、translateY(y)、translateZ(z)、translate3d(x,y,z):定义位置的移动距离

rotate(angle)、rotateX(a)、rotateY(a)、rotateZ(a)、rotate3d(x,y,z,angle):定义元素的旋转角度

2.perspective属性

perspective 属性定义 3D 元素距视图的距离,以像素计。该属性允许您改变 3D 元素查看 3D 元素的视图。

当为元素定义 perspective 属性时,其子元素会获得透视效果,而不是元素本身。

注释:perspective 属性只影响 3D 转换元素。

提示:请与 perspective-origin 属性一同使用该属性,这样您就能够改变 3D 元素的底部位置。

3.transform-style属性

transform-style: flat|preserve-3d; 默认值为flat,表示子元素以2D平面呈现;perserve-3d表示子元素以3D平面呈现

4.transform-origin属性

transform-origin 属性允许您改变被转换元素的位置(可以理解为元素以哪个位置为旋转原点)。

语法:

transform-origin: x-axis y-axis z-axis;

属性演示效果: 戳我

默认值为: 50% 50% 0

三、酷炫button

效果:(渣渣像素(/ □ \))

看下Twitter 做的 立体按钮效果,类似翻盖的动作是怎么做的。

HTML部分:

<body class="body">
<section>
  <div class="button">
    hello, welcome to the new world!
  </div>
  <div class="cover">
    <div class="innie"></div>
    <div class="spine"></div>
    <div class="outie"></div>
  </div>
  <div class="shadow"></div>
</section>
</body>

CSS部分:

<style>
      section, section div {
        transition-duration: .6s;
      }

      * { box-sizing: border-box; }
      html, body { height: 100%; }
      body {
        display: flex;
        flex-direction: column;
        justify-content: center;
        align-items: center;
        background-image: -webkit-radial-gradient(center top, circle farthest-corner, #FFFFFF 0%, #D8DFE9 100%);
        background-image: radial-gradient(circle farthest-corner at center top, #FFFFFF 0%, #D8DFE9 100%);
        overflow: hidden;
      }

      section, .button { transition-timing-function: ease; }

      section {
        display: inline-block;
        position: relative;
        padding: .375rem .375rem 0;
        height: 2.5rem;
        background: #A9ADB6;

1.倒影的实现

基本语法:

img {
    -webkit-box-reflect: below;
}

offset属性值定义图片和倒影影像之间的间距:

img {
    -webkit-box-reflect: below 3px;
}

给倒影增加消影效果:

-webkit-box-reflect:below 3px -webkit-linear-gradient(top,rgba(0,0,0,0) 40%,rgba(0,0,0,0.5));
