代码示例1
#container {
    border: solid gold 1px;   
    width: 400px;
    height: 200px;
    background:rgba(56,255,255,0.1);
}

#box {
    border: solid silver 1px;
    margin: 10px;
    width: 300px;
    height: 100px;
    background:rgba(205,206,255,0.1);
      transition: 2s background;
}

// if you then want to apply an animation, do it on background-color instead of opacity
