CSS，Flex瀑布流父元素宽度的问题
如下代码，我通过Flex写了一个类似瀑布流的父元素。宽度我不希望固定，而是希望根据子元素的数量将父元素撑大。
于是我设置了一个width: max-content。
但子元素明明换行了，父元素却没有撑开。
<!DOCTYPE html>

<style>
.father {
display: flex;
flex-direction: column;
flex-wrap: wrap;
background-color: chartreuse;
width: max-content;
max-height: 30vh;
}
.father>div {
border: 1px solid saddlebrown;
width: 100px;
height: 20px;
display: grid;
place-items: center;
}
</style>
</head>
<body>
<div class="father">
<!-- 模拟瀑布流，子元素数量不定 -->
<div>D1</div>
<div>D2</div>
<div>D3</div>
<div>D4</div>
<div>D5</div>
<div>D6</div>
<div>D7</div>
<div>D8</div>
<div>D9</div>
<div>D10</div>
<div>D11</div>
<div>D12</div>
<div>D13</div>
<div>D14</div>
<div>D15</div>
<div>D16</div>
</div>
</body>
</html>
解决办法
方案一：
.father {
display: flex;
flex-wrap: wrap;
background-color: chartreuse;
max-height: 30vh;
}
.father > div {
border: 1px solid saddlebrown;
flex: 0 1 100px;
height: 20px;
display: inline-grid;
place-items: center;
}
方案二：
.father {
display: grid;
grid-template-columns: repeat(auto-fill, 100px);
background-color: chartreuse;
max-height: 30vh;
}
.father > div {
border: 1px solid saddlebrown;
height: 20px;
display: inline-grid;
place-items: center;
}
