Question

我在Bootstrap 4.0中有响应图像问题。我使用class="img-fluid"，但似乎不起作用。

我在Chrome上使用附加组件检查其他设备（iPhone 4），但该图像无法在设备监视器上缩放。

这是我的代码：

<!doctype html>
    <html lang="en">
    <head>
    <title>Màn hình danh sách điện thoại</title>

    <body>
    <div class="container-fluid">
        <div class="row border border-primary mt-1 ml-1 mr-1 rounded">
            <img src="img/PET.png" style="width: 8rem" class="img-fluid float-left pb-2">
            <div class="col-md-6 text-center text-danger">
                 <h5 class="font-weight-bold">CỬA HÀNG ĐIỆN THOẠI PET</h5>

                 <h5>Điện thoại: 0907.888.511</h5>
            </div>
            <div class="col-md-6">      
            </div>
        </div>
    </div>
    <!-- jQuery first, then Popper.js, then Bootstrap JS -->

我希望这张图片像这样：

Answer 1

在img中包装div标记，然后在此处而不是在class="img-fluid float-left pb-2"中设置img。

并使用col-6进行第二格划分。

        <div class="col-md-6">      
        </div>
    </div>
</div>

Answer 2

在CSS中尝试

objcon.execute "insert into logs (member,refer) values (12,12345)"
objcon.execute "select top 1 id from logs order by id desc"

Answer 3

将图像包裹在.row div内的额外div中，如下所示：

<div class="container">
    <div class="row">
        <div class="col">
            <img class="img-fluid" src="my-image.jpg" />
        </div>
    </div>
</div>

注意：.col类不是必需的，但我发现它使事情与使用容器和行时所期望的方式保持一致
