如何堆叠和动画 2 svg 路径？

Question

我想通过用水填充圆圈并将我的徽标移动到圆圈内来为我的徽标设置动画。我有 2 个单独的 svg 路径。一是水，二是我的标志。 当我尝试通过放入 div #banner 为它们设置动画时，我得到了两个动画，但徽标“看不见”。我尝试添加 z 索引，但没有帮助。 这是我的代码：

 .logo{z-index:1000;
    position: relative;}
    
    #banner {
        border-radius: 50%;
        width: 150px;
        height: 150px;
        background: #b7c6ce;
        overflow: hidden;
        backface-visibility: hidden;
        transform: translate3d(0, 0, 0);
    }
    #banner .fill {
        animation-name: fillAction;
        animation-iteration-count: 1;
        animation-timing-function: cubic-bezier(.2, .6, .8, .4);
        animation-duration: 4s;
        animation-fill-mode: forwards;
    }
    #banner #waveShape {
        animation-name: waveAction;
        animation-iteration-count: infinite;
        animation-timing-function: linear;
        animation-duration: 0.5s;
        width:300px;
        height: 150px;
        fill: #04ACFF;
        z-index:-1;
    }
    
    @keyframes fillAction {
        0% {
            transform: translate(0, 150px);
        }
        100% {
            transform: translate(0, -5px);
        }
    }
    @keyframes waveAction {
        0% {
            transform: translate(-150px, 0);
        }
        100% {
            transform: translate(0, 0);
        }
    }

Answer 1

你有两个问题：

1. 徽标在 SVG 文件中位于首位，因此隐藏在蓝色的水后面。您需要移动它，使其位于水路之后。

2. 徽标相对于其他所有内容都太大了，因此您需要稍微缩放和移动它，使其位于正确的位置并且大小合适。为此，我向徽标路径添加了一个转换：

   transform="scale(0.3,0.3) translate(30,-30)"
   

通过这些更改，您将获得更好的结果。
