在保持縱橫比的同時縮放SVG

我有一個矩形的 SVG，我試圖使用width設定為多個em's的 CSS屬性來放大和縮小它。但是，我發現縱橫比沒有保留，圖示沿水平軸被切斷。

有沒有辦法只設定 CSSwidth屬性并讓圖示在保持縱橫比的同時自動調整其高度？理想情況下，我想要一個 CSS 解決方案，因為如果解決方案涉及更改 SVG 本身，我有大量的 SVG 需要更新（但如果那是唯一的解決方案，則可以）。

.icon {
  display: block;
  width: 10em;
  height: auto;

設定overflow: unset;。瀏覽器的用戶代理是它自己的默認設定。

svg:not(:root) {
    overflow: hidden;

更改 svg 的視圖框以viewBox="0 0 512 512"解決該問題。然后您可以設定width="448" height="512"保持該縱橫比：

我添加了紅色邊框以顯示縱橫比。

.icon {
  display: block;
  width: 10em;
  height: auto;
  border: 1px solid red;
}
