使用Bootstrap中的.btn-sm类创建一个小按钮。
您可以尝试运行以下代码来创建小于默认大小的按钮-
<!DOCTYPE html> <html> <head> <title>Bootstrap Example</title> <link rel = "stylesheet" href = "https://maxcdn.bootstrapcdn.com/bootstrap/4.1.1/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/4.1.1/js/bootstrap.min.js"></script> </head> <body> <p>Click below if you want to know the warning message:</p> <button type = "button" class="btn btn-warning">Warning</button> <p>Click below if you want to know the result:</p> <button type="button" class = "btn btn-primary btn-sm">Result</button> </body> </html>
