Question

在桌面模式下，图像会在“全名”和“表格编号”之间形成空白。如何使全名列从表单编号列的下方开始？我知道我可以将全名放在“表单编号”列div中，但是可以在单独的列中使用全名。

问题是，Bootstrap 4使用flexbox，因此每一行都是最高列的高度。如果您有单独的列，那么使它起作用的唯一方法是使用浮点数覆盖flexbox并重新排序列...

<div class="container-fluid">
    <div class="row d-sm-block d-flex">
        <div class="col-sm-4 float-right order-last">
            <img src="https://i.imgur.com/rC8Btb0.jpg" height="200px" width="200px" alt="image">
        </div>
        <div class="col-sm-4 float-left">
            Form Number: <span class="line">21129012</span>
        </div>
        <div class="col-sm-4 float-left">
            Hostel: <span class="line">(Yes / No)</span>
        </div>
        <div class="col-sm-4">
            Full Name: <span class="line">(Yes / No)</span>
        </div>
    </div>
</div>

通过为200像素的图像设置内联样式，可以设置整个引导程序行的高度。引导行基于flexbox，这就是为什么全名div不在您希望的位置的原因。您应该在下面加上全名，或者以其他方式重组HTML。
