css3animation是个好东西,之前应景的七夕表白爱心图。(都是中午午休时候的突发奇想。)
想想,应该在很多应节场合用css玩点有意思的。
突然想到上次的月食,那就玩玩。
看了一个div炫技网站.
画个月亮嘛,还是尝试用一个div来实现,主div做背景黑夜,before做月亮,after做挡住月亮的黑影。
position控制位置,用animation控制动画。

 .moonback{
    width: 600px;
    height: 600px;
    background-color: #000;
    margin: 0 auto;

    position: relative;

  }
  .moonback::before{
    content: ",";
    display: block;
    position: absolute;
    left: 200px;
    top: 100px;

    width: 200px;
    height: 200px;
    background-color: #ff0;
    border-radius: 100px;
  }
  .moonback::after{
    content: " ";
    display: block;
    position: absolute;
    left: 26px;
    top: 0px;

    width: 200px;
    height: 200px;
    background-color: #000;
    border-radius: 100px;

    -webkit-animation: 8s dog linear infinite;
    -moz-animation: 8s dog linear infinite;
    animation: 8s dog linear infinite;
  }

  @-webkit-keyframes dog {
    0% { 
      left:27px;
      top: 0px;
    }
    100% { 
      left: 399px;
      top: 216px;
    }
  }
  @-moz-keyframes dog {
    0% { 
      left:27px;
      top: 0px;
    }
    100% { 
      left: 399px;
      top: 216px;
    }
  }
  @keyframes dog {
    0% { 
      left:27px;
      top: 0px;
    }
    100% { 
      left: 399px;
      top: 216px;
    }
  }

最好body也设成背景黑,那就更好了~


等等,看不到星星的天空,缺少了幸福感。
正好偷师一下,一个div里的美队盾做法,直接用
也给个动画效果,放大缩小~

.star{
    position: absolute;
  }
  .star::before{
    content: "★";
    display: block;
    position: absolute;
    left: 10px;
    top: 20px;

    width: auto;
    height: auto;
    color: #fff;
    -webkit-transform:scale(0.5);
    -moz-transform:scale(0.5);
    transform:scale(0.5);

    -webkit-animation: 1s starlight linear infinite;
    -moz-animation: 1s starlight linear infinite;
    animation: 1s starlight linear infinite;
  }
  .star::after{
    content: "★";
    display: block;
    position: absolute;
    left: 40px;
    top: 120px;

    width: auto;
    height: auto;
    color: #fff;
    -webkit-transform:scale(0.5);
    -moz-transform:scale(0.5);
    transform:scale(0.5);

    -webkit-animation: 2s starlight linear infinite;
    -moz-animation: 2s starlight linear infinite;
    animation: 2s starlight linear infinite;
  }

  @-webkit-keyframes starlight {
    0% { 
      -webkit-transform:scale(0.5);
    }
    100% { 
      -webkit-transform:scale(0.1);
    }
  }
  @-moz-keyframes starlight {
    0% { 
      -moz-transform:scale(0.5);
    }
    100% { 
      -moz-transform:scale(0.1);
    }
  }
  @keyframes starlight {
    0% { 
      transform:scale(0.5);
    }
    100% { 
      transform:scale(0.1);
    }
  }

效果图如下:

完毕,嗯,再给月亮加个颜色渐变?
