提问by Dan
I have a problem with a template. On a large screen, it's look fine, like this:
我的模板有问题。在大屏幕上，它看起来不错，像这样：
But when I resize my browser, the content won't push the footer down. Here is a picture:
但是当我调整浏览器的大小时，内容不会将页脚向下推。这是一张图片：

Removing position:absolute;from the footerin the css appears to work. Perhaps consider having it set to absolute at wider screen sizes using media queries if having position:absoluteis absolutely (pardon the pun) necessary.
position:absolute;从footercss 中删除似乎有效。如果position:absolute绝对（请原谅双关语）有必要，也许可以考虑使用媒体查询在更宽的屏幕尺寸下将其设置为绝对值。
I provided a snippet with the absolute positioning removed, as well as the potential addition to a media query, which is commented out, but there to demonstrate.
我提供了一个删除了绝对定位的片段，以及对媒体查询的潜在添加，该内容已被注释掉，但用于演示。

The way Bootstrap sees how you want to change sizes for different screen sizes are in the column size identifiers. And each number is a fraction of 12.
Bootstrap 看到您希望如何更改不同屏幕大小的大小的方式在列大小标识符中。每个数字都是 12 的分数。
<div class="footer-col col-md-4">
means you want the footer to take 4/12 of the screen on devices medium or higher. To designate that you want it to be different on different sizes, you would put something like
意味着您希望页脚在中等或更高的设备上占据屏幕的 4/12。要指定您希望它在不同尺寸上有所不同，您可以输入类似
<div class="footer-col col-md-4 col-sm-12">
to mean that you want it to take up 4/12 of the screen on medium devices or larger, and 12/12 of the screen on small devices up to medium.
这意味着您希望它在中型设备或更大的设备上占据 4/12 的屏幕，在小型设备上占据 12/12 的屏幕，直到中型设备。

You have inline styling on your header <img>tag.
您的标题<img>标签上有内联样式。
<img class="img-responsive" src="<?php echo base_url(); ?>assets/img/simple_img.png" alt="" style="height: 200px;">
I would recommend trying to use a new class on that <img>tag, then apply a new @mediaquery to adjust height for different screen sizes.
我建议尝试在该<img>标签上使用新类，然后应用新@media查询来调整不同屏幕尺寸的高度。
Also, having the .img-responsive class on that element may also be conflicting with the inline height styling.
此外，在该元素上使用 .img-responsive 类也可能与行内高度样式相冲突。
回答by Rahul
Add the class "position-relative"
添加“位置相对”类
<!-- Footer Starts -->
<div class="container-fluid">
<div class="navbar fixed-bottom position-relative">
<p>You Footer Content<p>
</div>
</div>
<!-- Footer ends -->
