在任何HTML文本周围使用默认的<blockquote>。您还可以添加一个<small>标记，用于标识报价的来源，并使用.pull-right类将blockquote右对齐：
<!DOCTYPE html> <html> <head> <title>Bootstrap pull-right class</title> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://stackpath.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://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script> </head> <body> <blockquote> <p>This is a default blockquote example. This is a default blockquote example. This is a default blockquote example.This is a default blockquote example. This is a default blockquote example.</p> </blockquote> <blockquote> This is a blockquote with a source title. <small>Someone famous in <cite title = "Source Title">Source Title</cite></small> </blockquote> <blockquote class = "pull-right">This is a blockquote aligned to the right. <small>Someone famous in <cite title = "Source Title">Source Title</cite></small> </blockquote> </body> </html>
