使用Bootstrap，您可以轻松地将标题添加到缩略图。
您可以尝试运行以下代码来添加HTML标题-
<!DOCTYPE html> <html> <head> <title>Bootstrap Example</title> <link href = "/bootstrap/css/bootstrap.min.css" rel = "stylesheet"> <script src = "/scripts/jquery.min.js"></script> <script src = "/bootstrap/js/bootstrap.min.js"></script> </head> <body> <div class = "row"> <div class = "col-sm-6 col-md-3"> <div class = "thumbnail"> <img src = "/bootstrap/images/kittens.jpg" alt = "Kittens"> </div> <div class = "caption"> <h3>Thumbnail Heading</h3> </div> </div> </div> </body> </html>
