css - 使用 float 网格模式内容将页脚贴在底部

Question

我有一个基于网格系统的网站，因此所有列都 float 到左侧。

这意味着主要的 .content div 没有高度，因为所有包含它的 div 都是 float 的并且在 HTML 流之外，所以 body 没有高度。

我已经搜索并尝试过类似 the push div to stick footer 的东西, 或 jQuery 代码 abobe:

$( function () {    
    var height_diff = $( window ).height() - $( 'body' ).height();
    if ( height_diff > 0 ) {
        $( 'footer' ).css( 'margin-top', height_diff );
    }    
});

这些尝试都没有给出积极的结果，因为 body 根本没有高度，即使它在视觉上充满了列，即使将它们放在显示为 block 的 .row div 中，问题依然存在。

解决这个问题的最佳方法是什么？

HTML:

<div class="container main clearfix">
                    <div class="grid_12">
                      <p>
                        970
                      </p>
                    </div>
                    <!-- end .grid_12 -->
                    <div class="clear"></div>
                    <div class="grid_1">
                      <p>
                        57
                      </p>
                    </div>
                    <!-- end .grid_1 -->
                    <div class="grid_11">

                      </p>

我不明白你的问题实际上是什么，如果你想要一个粘性页脚分开 whcch 应该固定在屏幕的底部但是对于粘性页脚使用下面的 CSS 到页脚

CSS

1. 要使页脚始终位于页面底部并使其即使在滚动页面时也可用，请使用以下 css

   页脚{
位置:固定；
底部:0；


DEMO

1. 要将页脚放置在页面底部并且仅当用户移动到页面底部时才能看到，请使用下面的 css
页脚{
position:absolute；
}
以上将使您的页脚保持在您的 container div 高度旁边。
