css之自动换行

自动换行问题,正常字符的换行是比较合理的,而连续的数字和英文字符常常将容器撑大,挺让人头疼,下面介绍的是CSS如何实现换行的方法

对于div,p等块级元素
正常文字的换行(亚洲文字和非亚洲文字)元素拥有默认的white-space:normal,当定义的宽度之后自动换行
html
<div id="wrap">正常文字的换行(亚洲文字和非亚洲文字)元素拥有默认的white-space:normal,当定义</div>
css
#wrap{white-space:normal; width:200px; }

1.（IE浏览器）连续的英文字符和阿拉伯数字,使用word-wrap : break-word ;或者word-break:break-all;实现强制断行

#wrap{word-break:break-all; width:200px;}
或者
#wrap{word-wrap:break-word; width:200px;}

<div id="wrap">abcdefghijklmnabcdefghijklmnabcdefghijklmn111111111</div>

效果：可以实现换行

2.（Firefox浏览器）连续的英文字符和阿拉伯数字的断行,Firefox的所有版本的没有解决这个问题,我们只有让超出边界的字符隐藏或者,给容器添加滚动条

#wrap{word-break:break-all; width:200px; overflow:auto;}

<div id="wrap">abcdefghijklmnabcdefghijklmnabcdefghijklmn111111111</div>

效果：容器正常，内容隐藏

对于table

1. (IE浏览器)使用 table-layout:fixed;强制table的宽度,多余内容隐藏

<table style="table-layout:fixed" width="200">
<tr>
<td>abcdefghigklmnopqrstuvwxyz1234567890ssssssssssssss
</td>
</tr>
</table>

效果：隐藏多余内容

2.(IE浏览器)使用 table-layout:fixed;强制table的宽度,内层td,th采用word-break : break-all;或者word-wrap : break-word ;换行

<table width="200" style="table-layout:fixed;">
<tr>
<td width="25%" style="word-break : break-all; ">abcdefghigklmnopqrstuvwxyz 1234567890
</td>
<td style="word-wrap : break-word ;">abcdefghigklmnopqrstuvwxyz 1234567890
</td>
</tr>
</table>

效果：可以换行

3. (IE浏览器)在td,th中嵌套div,p等采用上面提到的div,p的换行方法

4.(Firefox浏览器)使用 table-layout:fixed;强制table的宽度,内层td,th采用word-break : break-all;或者word-wrap : break-word ;换行，使用overflow:hidden;隐藏超出内容，这里overflow:auto;无法起作用

<table style="table-layout:fixed" width="200">
<tr>
<td width="25%" style="word-break : break-all; overflow:hidden; ">abcdefghigklmnopqrstuvwxyz1234567890</td>
<td width="75%" style="word-wrap : break-word; overflow:hidden; ">abcdefghigklmnopqrstuvwxyz1234567890</td>
</tr>
</table>

效果：隐藏多于内容

5.(Firefox浏览器) 在td,th中嵌套div,p等采用上面提到的对付Firefox的方法
运行代码框
最后，这种现象出现的几率很小，但是不能排除网友的恶搞。如果有什么问题请到我的留言本提出

下面是提到的例子的效果

The overflow declaration

Explorer Windows, with the exception of Explorer 7 in Strict Mode, implements overflow: visible incorrectly. See below.

The overflow declaration tells the browser what to do with content that doesn't fit in a box. This assumes the box has a height: if it doesn't, it becomes as high as necessary to contain its contents, and the overflow declaration is useless.

You can assign four values to overflow and they should give the following results:

visible. the content flows out of the box.
hidden. the overflowing content is completely hidden, not accessible to the user.
auto. show scrollbars where necessary (horizontal or vertical or both).
scroll. always show horizontal and vertical scrollbars, regardless of whether they're necessary. This value is never used; you generally want auto.

Test

Safari cannot dynamically change overflow to auto or scroll.

Test overflow by changing its value for the test element.

This is the test element. It has the following styles:

width: 30em;
height: 5em;
padding: 1em;
border: 1px solid #cc0000;

One more line of text

`overflow: visible` and Explorer Windows

Explorer Windows (with the exception of Explorer 7 in Strict Mode) implements overflow: visible incorrectly.

The correct behaviour is that the element with overflow: visible becomes as high and wide as the CSS orders, and that any content that doesn't fit spills out of the box, overlapping, if necessary, the content that follows.

Screenshot: Correct implementation of overflow: visible

Instead, Explorer Windows (with the mentioned exception) stretches up any element with overflow: visible until the content fits in it. Effectively width serves as min-width.
