我正在使用这个 Bootstrap 模板 here为我的应用程序创建一个页面。 在中心列 (col-sm-7) 中，我将有一个表单，我想在底部创建一个页脚/导航栏/区域，它固定在底部，以便我可以添加按钮(例如保存，接下来，返回)。
我正在尝试不同的东西，比如页脚元素、带有“navbar-fixed-bottom”的 Bootstrap 导航栏和一个带有 div 的普通行，其中 bootom 为 0 且位置固定，但没有似乎工作正常。
问题是当我添加上述任何样式时，固定在底部的元素的宽度不会保持在中心 (col-sm-7) 列内。它最终跨越整个页面或不够。我只是无法将其包含在居中的列中
这里的任何建议都可以将任何东西固定在中心列的底部，这样我就可以在其中放置按钮，这将很有帮助!
这是我到目前为止尝试过的示例
这个有页脚。

</html>最佳答案
首先你需要了解基本结构，你不需要将页脚放在-col类中，看看结构
在标准情况下，您可以像这样添加代码
<header>
<nav>
<!-- Put the navbar here -->
</nav>
</header><!-- Header -->
<section>
<div class="container">
<div class="row">
<div class="col-sm-3">
</div><!-- .left items like my profile etc.. -->
<div class="col-sm-7">
</div><!-- . main content section here-->
<div class="col-sm-2">
</div><!-- /. upcomming section will be here -->
</div><!-- /.row -->
</div><!-- /.container -->
</section> <!-- /.content section -->
<footer>
</footer><!-- footer always stay at bottom -->
我已经像这样更改了你的代码
header,
.full-width {
float: left;
width: 100%;
}
footer {
background-color: #555;
color: white;
padding: 15px;
border: 1px solid black;
text-align: center;
