要将元素形成为圆形,请在Bootstrap中使用.rounded-circle类。
它很容易实现-
<div class="test rounded-circle"></div>
让我们看一个在Bootstrap中创建一个圆的例子-
<!DOCTYPE html> <html lang="en"> <head> <title>Bootstrap Example</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css"> <script src="https://cdn.staticfile.org/jquery/3.3.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script> <style> .test { width: 300px; height: 300px; background-color: orange; } </style> </head> <body> <div class="container"> <h2>Circle</h2> <p>We have a circle below:</p> <div class="test rounded-circle"></div> </div> </body> </html>
