是否可以使<div>适合其css掩码大小？假设掩码图像是100px x 100px。有可能让<div>自动变大100px x 100px吗？(不是通过将style="width: 100px; height: 100px"放在div上(
我在找style="width: 100%; height: auto"之类的东西。它不一定是<div>元素，它可以是任何东西(可能像<img>？(
这里有一些东西可以玩(你们可以编辑吗？(：
.logo {
background-color: black;
mask-image: url('https://s.cdpn.io/3/kiwi.svg');
width: 100px;
height: 100px;
}
.image {
content: url('https://s.cdpn.io/3/kiwi.svg');
width: 100px;
height: auto;
}<div class="logo"></div>
<img class="image">如果你们不能编辑上面的一个，这里有一个你们可以编辑的(在Angular中，我不确定我还能在哪里创建这样的东西？(

如果你的SVG总是一样的，那么你知道它的比例，所以你可以考虑填充技巧
