使用.affix时，元素宽度错误
使用.affix时，元素宽度错误
提问于 2017-08-09 07:30:48
在此example中，您可以看到，当我们向下滚动时，搜索字段显示较大的宽度。如果我删除标签(带有搜索标志图标)-一切正常。我在其他标签上也遇到了同样的问题，比如，还有其他元素类，比如.panel-group、.panel-heading和e.t.c。我怎么才能修复它？

解决这个问题的一种方法是添加left: 15px; right: 15px;来匹配父col的填充，这就是当元素没有被附加时控制宽度的东西。

.affix {
top: 20px;
left: 15px;
right: 15px;
}

<h3>Fixed (sticky) vertical sidenav on scroll</h3>
<p>Scroll this page to see how the left navigation menu behaves with data-spy="affix".</p>
<p><strong>The left menu sticks to the page when you have scrolled a specified amount of pixels.</strong></p>
