页面里有一个container, 里面有两个div





已知container的宽是800
让leftDiv宽为200, rightDiv宽为600 横向排列起来,请问要怎么写?

如果不使用float应该怎么实现?(我的页面比这个复杂很多,用了float后ie和firefox显示差异太大,我想知道有没有什么好的技巧能够代替float,所以提了这个问题) 


回复讨论(解决方案)

1,页面再复杂,各种浏览器对float解释的还是不错的。
2,不用float的话,我唯一知道的就是绝对定位了。。。一侧用绝对定位,另外一侧用margin 赋值。
3,推荐还是用float,绝对定位会越搞越麻烦。
4,float的话,左右都要float,下面用clear清除一下,就不会有问题了。ie6 下的双倍边距用_display:inline解决。firefox下的清除,可以写#container:after{overflow:hidden;display:block,content:"";height:0;line-height:0;}就可以解决了。

几点额外的建议:
1. 不要认为你把container宽度设为800,leftDiv设为200,rightDiv设为600就能拥有“实诚”的布局。
实际上,有些宽度是你很容易忽略的,比如border,padding,margin,这些都是很容易忽略的,建议把leftDiv和rightDiv按百分比设定,并且加起来小雨100%。比如:leftDiv = 24%, rightDiv = 74%。
2. 不用一味地float:left; 不要忘记还有float:right。给rightDiv设定float:right有时会有意想不到的收获。

简单地,可以这样写:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=gb_2312" /><title>No Title</title></head><style>#container { width:800px; padding:0; margin:0 auto; height:100%;}#leftDiv { width:24%; float:left; text-align:center; line-height:600px; height:600px; display:block; background-color:#ccc; color:#f00;}#rightDiv { width:74%; float:right; text-align:center; line-height:600px; height:600px; display:block; background-color:#c00; color:#fff;}</style><body><div id="container"> 	<div id="leftDiv">	leftDiv	</div> 	<div id="rightDiv">	rightDiv	</div> </div> </body></html>
Copy after login


table
布局格式已经固定的话 最外面直接包TABLE一行2列 何必写这么多CSS搞自己头晕 而且里面2个DIV是独立的以后修改也不麻烦

display:inline吧







float这里就不贴代码了,不用float的话,可以用定位来做,这种方法的优点是可以按DIV的顺序来决定优先显示的顺序,代码如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"  xml:lang="zh-CN" lang="zh-CN"><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /></head><body><style type="text/css">body {font-size:9pt;text-align:center;}#container {position:relative;margin:auto;width:800px;height:200px;}#leftDiv {position:absolute;top:0;left:0;width:200px;height:200px;background:#ddd;}#rightDiv {position:absolute;top:0;right:0;width:600px;height:200px;background:#eee;}</style>1、先显示leftDiv<div id="container"> <div id="leftDiv">leftDiv</div> <div id="rightDiv">rightDiv</div> </div>2、先显示rightDiv<div id="container"> <div id="rightDiv">rightDiv</div> <div id="leftDiv">leftDiv</div> </div></body></html>
Copy after login

说白了就是如果不想用float定位,那么就请使用position:absolute吧
使用时请注意在父层div中设定position:relative
然后left和right两个子层position:absolute

多说一句,子层这时候会脱离文本流,但是如果想让此div中数据能够自动撑开div,那么请在该层最下面添加一个清除浮动的元素如

HTML code
body{
font-size:9pt;
text-align:center;}
#container{
position:relative;
margin:auto;
width:800px;
height:200px;}
#leftDiv{
position:absolute;
top:0;
left:0;
width:200px;
height:200px;
background:#ddd;}
#rightDiv{
position:absolute;
top:0;
right:0;
width:600px;
height:200px;
background:#eee;}

1、先显示leftDivleftDiv

rightDiv


2. Display rightDiv firstrightDiv< /div>leftDiv

If floating positioning is not allowed, let’s use absolute positioning

The default div is a row-level tag. If you do not use float, you can display it: inline and then set the width of the two divs appropriately

In summary
When you start learning css,
Playing with float:left ,right is a big deal...

Not bad, I’ve studied them all,,,

Use positioning or TBALE

float:right;

Just use float, the effect of each browser can be set almost, it is impossible to be exactly the same

1. float
2. position
3. diaplay: inline
4 , table
