我对我的自举联系表格感到非常满意，但是当我将其最小化到细胞水平时，它消失了，我必须一直向右滚动。谁能帮我用我的CSS完美缩小尺寸？
另外，有什么方法可以使切换按钮在可见时居中，而不是向左浮动。

最佳答案
也许可以使用引导行和列参数来代替使用单独的li标记。尝试这样的事情：

<li class="nav-item">
<div class="row">
<div class="col-xs-2">
<a class="nav-link" href="https://www.instagram.com/eddiearkmunoz/" title="Follow on Instagram" target="_blank"><i class="fa fa-instagram" aria-hidden="true"></i></a>
