在Bootstrap中使用.container-fluid类来设置一个跨越屏幕整个宽度的容器。
您可以尝试运行以下代码来实现Container-fluid类
<!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> <div class = "container-fluid"> <h3>Container fluid</h3> <div class = "w-100 bg-danger">Normal width</div> <div class = "w-75 bg-warning">Width is 75%</div> <div class = "w-50 bg-success">Width is 50%</div> <div class = "w-25 bg-warning">Width is 25%</div> </div> </body> </html>
