HTML,CSS与中心div问题 [英] html, css with center div problem
问题描述
我想用三个分隔列(用不同的颜色)创建居中的html页面。我无法找到我的#container1在CSS中的解决方案。红色从左侧扩展(离开中心页面)。这里是: http://imgur.com/D3ZAV

(抱歉格式不对,我找不出原因你真的需要重新考虑你对这个问题的处理方式。
< div id =container> 我会建议:3个浮动div包装在一个容器中。
< div id =column1> Lorem ipsum< / div>
< div id =column2> Dolor sit amet< / div>
< div id =column3> Mauris orci< / div>
< / div>
至于您的CSS,您可以使用一些重要的东西:
#container {
overflow:hidden; //这将清除浮动列
width:960px;
}
#column1 {
float:left;
width:320px;
背景:#f00;
}
#column2 {
float:left;
width:320px;
背景:#0f0;
}
#column3 {
float:left;
width:320px;
背景:#00f;
$ / code>
实质上:
- 包装浮动并使用
overflow:hidden;
清除它们 - 浮动的总宽度为等于容器的宽度
I would like to create centered html page with three separated columns (with different colors). I can't find solution for my #container1 in css. The red color is spreading from left side(out of the centered page). Here it is: http://imgur.com/D3ZAV can someone please help me? thanks

(sorry for bad formatting, i can't figure out why it is so shitty )
You really need to reconsider your approach to this problem.
I'd suggest: 3 floated divs wrapped in a container.
<div id="container">
<div id="column1">Lorem ipsum</div>
<div id="column2">Dolor sit amet</div>
<div id="column3">Mauris orci</div>
</div>
And as for your CSS, there are a few significant things you can build on:
#container {
overflow: hidden; //this will clear the floated columns
width: 960px;
}
#column1 {
float: left;
width: 320px;
background: #f00;
}
#column2 {
float: left;
width: 320px;
background: #0f0;
}
#column3 {
float: left;
width: 320px;
background: #00f;
}
Essentially:
- Wrap the floats and clear them using
overflow: hidden;
- The total width of the floats is equal to the width of the container
