如何使用CSS创建完美的3列布局，支持跨浏览器？如何使用CSS创建完美的3列布局，支持跨浏览器？
我有3个div的像
<div class="clm1">Some content</div>
<div class="clm2">Some content</div>
<div class="clm3">Some content</div>
试着用搜索引擎，但所有作了或CSS3。我需要一个完美的3列在基本的CSS。请帮助
更新 完美在这个意义上，所有的浏览器所需要的支持，但并易于修改
包裹在父元素全部三个（在我的例子一个<div>）。给所有三个<div>元素一个float:left; CSS属性和一个非自动width属性。然后使用Faux Columns trick给他们背景颜色。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<style type="text/css">
.three-columns .column {
width:33%;
float:left;
}
</style>
</head>
<body>
<div class="three-columns">
<div id="clm1" class="column">Some content</div>
<div id="clm2" class="column">Some content <br />Some content <br />Some content <br />Some content <br /></div>
<div id="clm3" class="column">Some content <br />Some content <br />Some content <br />Some content <br />Some content</div>
</div>
</body>
</html>
在这个例子中我已经采取改变你class属性id属性，因为他们并没有感到适合于class属性的自由。
在这里你去，直出从Dreamweaver没有巨大的编码。解释说，等：

1) Padding is only placed on the top and/or bottom of the divs. The elements within these divs have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.
2) No margin has been given to the columns since they are all floated. If you must add margin, avoid placing it on the side you're floating toward (for example: a right margin on a div set to float right). Many times, padding can be used instead. For divs where this rule must be broken, you should add a "display:inline" declaration to the div's rule to tame a bug where some versions of Internet Explorer double the margin.
3) Since classes can be used multiple times in a document (and an element can also have multiple classes applied), the columns have been assigned class names instead of IDs. For example, two sidebar divs could be stacked if necessary. These can very easily be changed to IDs if that's your preference, as long as you'll only be using them once per document.
4) If you prefer your nav on the right instead of the left, simply float these columns the opposite direction (all right instead of all left) and they'll render in reverse order. There's no need to move the divs around in the HTML source.

马修·詹姆斯·泰勒有一个模板here与我已经在很多场合使用了巨大的成功一个非常坚实的布局。他有几种灵活的布局可供选择。

有不少列在这里的模板：Three Column Layouts
当你说“完美”时，你是什么意思？列是相同的宽度？高度相同吗？它们的宽度和高度可以根据内容动态变化？ – DOK 2010-06-14 14:31:45
