Bootstrap 4 网页布局设计的难点

我试图在左侧显示侧边栏，在右侧显示主要的动态内容。在这里，我为侧边栏提供了

col-sm-3

，为内容提供了rest（

col-sm-9

）。 我在这里遇到的问题是，我的侧边栏不完全适合

col-sm-3

，因此侧边栏和主要内容之间的间隙很小（下图中的白色部分）。

如果我将侧边栏的网格减少到

col-sm-2

，那么主要内容会移回侧边栏，一些内容会被隐藏。在侧边栏的某个地方，我使用z-index作为1来管理背景图像、不透明度和内容

我怎样才能使侧边栏完全适合左侧的网格和右侧的动态内容，而中间没有这样的空白垂直空间

我也尝试过使用table，但在这样做的同时，我的内容移到了侧边栏的后面。解决办法是什么

这似乎是一个引导默认的填充和边距问题。将第3列和第9列的填充和边距归零，并相应地添加和删除

   <div class="container-fluid">
        <div class="row" style="padding:0; margin:0;">
            <div class="col-sm-3" style"padding:0; margin:0;">
                {{> home/sidebar}}
            </div>
            <div class="col-sm-9" style="padding:0; margin:0; background-color: #EEF1F3; ">
                {{{ body }}}
            </div>
        </div>
    </div>


{{>主页/侧边栏}
{{{body}}}
我用代码编辑了我的答案，这些代码应该将你的边距和填充置为零，并使所有内容都齐平。如果它不起作用，那么您还有一些其他问题。@John尝试发送一个指向该站点的链接或JS FIDDLE，或包含所有代码的代码片段，这样我们就可以看到问题所在并看到代码的运行情况。我已将边距和填充设置为0px。它也不起作用。请用叉子叉这个，帮我把它放在叉子上。
