Bootstrap 4.5 代碼未按預期工作

Bootstrap 4.5 代碼未按預期工作

楊魅力 2022-11-11 13:49:10
我是 Bootstrap 的初學者，我正在關(guān)注 bootstrap 文檔。盡管如此，我的代碼仍然無法正常工作。我的文件夾只包含一個 index.html 文件。Visual Studio 代碼截圖。<!doctype HTML><html><head><!-- Required meta tags --><meta charset="utf-8"><meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"><!-- Bootstrap CSS --><link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css"    integrity="sha384-9aIt2nRe3js3W69CrMinNGtLdWyYrnnKzHR26vu4tDT5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous"><title>WeGo</title></head><body><div class="container"><!-- This part is not working.
