div 上的全宽背景颜色 [英] full width background color on a div

问题描述

我正在使用 1120 像素的 css 响应式响应框架，或者它可以在我需要时充当固定网格.

我在 1120px 容器 div 中有一个 div，我想在其上应用全宽背景色.

div 的背景颜色当然只在容器 div 内，我想让它填满 body 元素的整个宽度.

现在的问题是 div 是由短代码自动生成的，所以我无法创建外部 div 并将其设置为 100% 宽度.

这是短代码中的标记:

<div class="toggle"><div class="toggle_title toggle_active">LINE-UP</div><div class="toggle_content" style="display:block;">Lorem ipsum sat dolor amet</div>

和这个 css :

.toggle{ margin-bottom: 5px;清楚:两者；向左飘浮;位置:相对；宽度:100%；}.toggle .toggle_title {位置:相对；字体大小:112.5%；字体粗细:700；填充底部:15px；左边距:25px；文字装饰:无；}

这里是一个FIDDLE

现在，问题是此标记位于宽度为 1120 像素的容器 div 下.我正在考虑添加 .toggle .toggle_title position:absolute;例如，将最小宽度设置为 1480 像素，但随后一切都会中断.

我相信这是解决此类问题的更好方法.谁能给我一些关于如何使这项工作的提示?谢谢！

解决方案

这是一种非常丑陋的方法.我发布这个是希望有人反对这个……但它有效.

将此添加到您的 CSS:

.toggle_title, .toggle_content {位置:相对；z-索引:2；}.toggle:before {内容:"";宽度:4000px；位置:绝对；高度:100%；背景颜色:红色；左:-50%；z-索引:1}

基本上，只需在 div 之前添加一个空内容，其宽度是预期屏幕分辨率的两倍，并将其定位到左侧 50% 以确保它拉伸整个距离.

你怎么看?

I'm using a 1120px css responsive framework responsive or it can act as a fixed grid whenever I need it.

I have a div inside the 1120px container div on which I want to apply a full width background color.

The background color of the div's is of course only inside the container div and I want to make it fill the full width of the body element.

Now the problem is that the div is generated automatically by a shortcode so I can not create an outer div and set it to 100% width.

Here is the markup from the shortcode:

<div class="toggle-default">
    <div class="toggle">
<div class="toggle_title toggle_active">LINE-UP</div>
<div class="toggle_content" style="display:block;">Lorem ipsum sit dolor amet</div>

</div>
    </div>

and this css :

.toggle{ margin-bottom: 5px; 
clear: both; float: left; 
position: relative;  
width: 100%;                
}
.toggle .toggle_title {
position: relative;
font-size: 112.5%;
font-weight: 700;
padding-bottom: 15px;
padding-left: 25px;
text-decoration: none;

}

and here is a FIDDLE

Now, the problem is that this markup is under a container div which has 1120px width. I was thinking to add on .toggle .toggle_title position:absolute; and set a min- width of 1480px for example but then everything will break.

I'm sure that is a better approach to this kind of issue. Can anyone give me some tips on how to make this work? Thank you!

解决方案

Here's a really ugly way to do this. and I'm posting this with an expectation of someone downvoting this... but it works.

Here's a fiddle for it http://jsfiddle.net/5mn22/8/

Add this to your CSS:

.toggle_title, .toggle_content {
    position:relative;
    z-index:2;
}

.toggle:before {
    content:"";  
    width:4000px;
    position:absolute;
    height:100%;
    background-color:red;
    left:-50%;
    z-index:1
}

Basically, just adding a null content before the div with a width double the size of expected screen resolution and position it to the left 50% to make sure it stretches the entire distance.

What do you think?
