阻止页脚div隐藏在内容div后面

标签： html css html5 css3

你好堆叠器，

我试图在我的票证底部放置一个页脚，但是放在页脚上方的图像div隐藏了页脚div。我怎么能出现这个？

我已附上以下相关代码，您也可以查看JSFiddle。在此先感谢您的帮助。

                <p>I go by the name of Kadeem Laurie and this is my brief portfolio. I am an events graduate currently developing an events marketing start-up. This website, which is responsive, was created from scratch using HTML, CSS and jQuery for the purpose of showcasing some of my digital proficiencies. I specialise in event management, digital content, SEO, marketing strategy, branding and front-end web design.</p>
                <p>Freedom of thought inspires me. I love conceptualising and seeing ideas evolve. I see myself as a marketeer who simply likes to make things look good, branding has thus always been my most favourable aspect of marketing. I studied event management in university and have organised a <a href=events.html> few events</a> of my own. I hope to integrate events within marketing strategy more. I like to ask the <a href="http://stackoverflow.com/users/1923610/kadeem-laurie?tab=profile" target=_blank>right questions</a> and find solutions from different perspectives.</p>
                <p>My favourite book is <a href=https://en.wikipedia.org/wiki/The_Prince>The Prince</a> by Nicolo Machievelli. My favourite dish is <a href=http://lifestyle.sapo.pt/sabores/receitas/arroz-de-marisco>Arroz De Marisco.</a>

                    <br>This website has been recently created so content is being added concurrently.</p>

你有几件事情要发生在这里：

首先，您使用浮动图像（.item）但不清除它们。无论何时浮动图像或任何其他对象，您都可以将其从normal flow中取出。这意味着父容器不知道它们存在，因此不为它们腾出空间。

有几种方法可以解决此问题 - 称为clearfix methods。在这种情况下，我使用了overflow属性。将overflow: auto添加到父.post-container。

.post-container {  overflow: auto;  }

第二个问题是，同一个容器（.post-container）相对位于其正常（静态）位置顶部400px处。

.post-container { top: 400px; }

这会将容器向下推过页脚元素400px。

为了弥补这种向下移动，页脚元素也需要移动400px。

.goodbye { bottom: -400px; }

因此，使用clearfix和一些定位，您的页脚最终会位于.global-container的底部。

只需将position: relative添加到CSS中的页脚即可。 内容div也与z-index: 0相对定位。因此，它正在超越你的页脚。仅添加position: relative会使其显示在图像上方。
