根据官方文档中的this示例,我注意到将在< 2000px的高度,我将在页脚下面有很多空白区域。
我无法根据this示例指定页脚的高度(它可能会动态增加),所以我想我不能将它粘贴到页脚?
如何解决这个问题?

在您评论中链接到的示例中,页脚实际上粘贴到页面底部的内容不是页脚高度,而是以下CSS规则:
.footer {
position: absolute;
bottom: 0;
}
如果您通过浏览器的开发者工具查看页脚并禁用height
CSS规则,则可以自行查看,页脚将继续位于页面底部。
就身体边缘而言,由于你的页脚没有固定的高度,你可以设置它的唯一方法是使用Javascript来测量页脚并在document.ready
上设置身体边距。参见附带的例子:
$(document).ready(function(){
var footerHeight = $('.footer').height();
$('body').css('margin-bottom', footerHeight);
});

/* Sticky footer styles
-------------------------------------------------- */
html {
position: relative;
min-height: 100%;
}
body {
/* Margin bottom by footer height */
margin-bottom: 60px;
}
.footer {
position: absolute;
bottom: 0;
width: 100%;
/* Set the fixed height of the footer here */
height: 60px;
background-color: #f5f5f5;
}
/* Custom page CSS
-------------------------------------------------- */
/* Not required for template or sticky footer method. */
body > .container {
padding: 60px 15px 0;
}
.container .text-muted {
margin: 20px 0;
}
.footer > .container {
padding-right: 15px;
padding-left: 15px;
}
code {
font-size: 80%;
}

使用Boostrap的粘性页脚,对于页脚的高度,使用此jquery,它检查页脚的高度并将其添加到html标记。 它在页面加载和Window.resize事件上运行,因此它适用于响应式项目。
$(document).ready(function(){
$(window).resize(function(){
$("html").css("padding-bottom",$(".footer").outerHeight())
}),
$("html").css("padding-bottom",$(".footer").outerHeight()
);
});
