在桌面模式下，图像会在“全名”和“表格编号”之间产生间隙。如何使全名列在表格编号列的正下方开始？我知道我可以将全名放在表格编号列 div 中，但是否可以在单独的列中使用全名。

【解决方案1】：

问题在于 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，使其工作的唯一方法是使用浮动覆盖弹性框并重新排列列...

<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>

【讨论】：

float: right 在该行内不起作用，因此您使用 d-sm-block 在所有设备上隐藏该行。

请说明您为修复代码所做的工作

【解决方案3】：

通过设置 200px 图像的内联样式，您可以设置整个引导行的高度。 Bootstrap 行基于 flexbox，这就是为什么您的全名 div 不在您想要的位置的原因。您应该将全名放在表格编号后面或以其他方式重组您的html。
