Bootstrap4：主體放大的模態渲染問題

Question

我正在嘗試使用將主體放大90％的Bootstrap html頁面。Bootstrap模態從右邊和底部顯示空格。為了顯示此問題，我將基本html頁面與modal 90％縮放。

當您單擊打開的模態時，您將在模態的右側和底部看到空間。.如何使用主體縮放90％渲染模態而沒有多余的空間。.所需的輸出是模態模糊背景應覆蓋整個屏幕..和模態主體應該位於x軸的中心，就像90％和100％的縮放比例一樣，只是90％的縮放比例是小字體

.modal-backdrop類使用100vh和100vw，並且由於我們應用了90％縮放，因此100vh對應於屏幕高度的90％； 100vw相當於屏幕寬度的90％；

解決方案 ：使用width: 100%; height: 100%;覆蓋此類width: 100%; height: 100%; width: 100%; height: 100%;

 .modal-backdrop { width: 100% !important; height: 100% !important; }
