引导布局内容表单元素扩展出列

Question

我有两列引导程序布局。 左栏是手风琴导航，右侧是主要内容。

左侧导航应该是固定宽度（在它到达断点之前） 但保持敏感，主要内容应保持响应。

我的问题是，我右侧的按钮似乎延伸到柱壁之外。按钮有一个固定的宽度和一个绝对的位置，但我怎么能修改它们，所以它们不会像这样延伸到列之外？

.container宽度假设宽度为1530px，但由于某种原因，它没有实现该样式。

Answer 1

您首先将.container类定义为宽度为1590，但随后将媒体查询max-width：1590类的.container添加为具有自动宽度，这将覆盖您的第一个规则。删除自动宽度规则。

阅读移动优先编码和使用最小宽度媒体查询，它将有助于避免将来出现这种情况。 此外 - 在自助训练中，你不能总共超过＆＃34; 12＆＃34;每行的col-width。

Answer 2

也许你必须在Bootstrap的col中使用另一个包装器，它被设置为position: relative;

<div class="row">
    <div class="col-sm-4">
        <div class="position-relative">
            absolute positioned elements
        </div>
    </div>
</div>

<强>更新

该列只是缩小以适应按钮。 尝试使用更宽的列来显示按钮。这是一个适用于带按钮的行的代码：

<label class="col-md-2 hidden-xs hidden-sm control-label custom-label" for="email">Email</label>
<div class="col-md-7 col-xs-12 col-sm-12 clearfix">
<div class="switch col-md-3 col-xs-12 col-sm-12 ">
    ...

希望有所帮助！

更新2：

您必须覆盖Bootstrap容器宽度。类似的东西：

@media (min-width: 1200px) {
   .container {
       width: 1600px !important;
    }
}
