css+div:让文本字符环绕在你的图片周围_css教程

　　看到上面的效果，你也许以为这是一张带文字的图片而已;呵呵，用你的鼠标去选取文字看看，发现了吧，这完完全全是一张图片和文字的组合，下面我就来介绍它是怎么做的。

　　先看看代码:

　　 以下是引用片段：
<div id=”info”>
<h2>TRACKING YOUR IMAGES</h2>
<div id=”holdit”>
<img src=”http://www.knowsky.com//imagelist/06/24/4fnpgj5042e6.jpg” alt=”Winnie the pooh” title=”Winnie the pooh” />
<em class=”a420″></em>
<em class=”a430″></em>
<em class=”a400″></em>
<em class=”a370″></em>
<em class=”a340″></em>
<em class=”a300″></em>
<em class=”a270″></em>
<em class=”a250″></em>
<em class=”a240″></em>
<em class=”a230″></em>
<em class=”a230″></em>
<em class=”a340″></em>
<em class=”a340″></em>
<em class=”a360″></em>
<em class=”a540″></em>
<em class=”a540″></em>
<em class=”a540″></em>
<em class=”a550″></em>
<em class=”a550″></em>
<em class=”a550″></em>
<em class=”a550″></em>
<em class=”a550″></em>
<em class=”a550″></em>

<p>”I shall have to wait until I catch up with it,” said Winnie-the-Pooh. “Now, look there.” He pointed to the ground in front of him. “What do you see there?”<br />
“Tracks,” said Piglet. “Paw-marks.” He gave a little squeak of excitement. “Oh, Pooh! Do you think its a–a–a Woozle?”<br />
“It may be,” said Pooh. “Sometimes it is, and sometimes it isnt. You never can tell with paw- marks.”<br />
With these few words he went on tracking, and Piglet, after watching him for a minute or two, ran after him. Winnie-the-Pooh had come to a sudden stop, and was bending over the tracks in a puzzled sort of way.<br />
“Whats the matter?” asked Piglet.<br />
“Its a very funny thing,” said Bear, “but there seem to be two animals now. This–whatever-it-was–has been joined by another–whatever-it-is–
and the two of them are now proceeding in company. Would you mind coming with me, Piglet, in case they turn out to be Hostile Animals?”<br />
Piglet scratched his ear in a nice sort of way, and said that he had nothing to do until Friday, and would be delighted to come, in case it really was a Woozle.<br />
“You mean, in case it really is two Woozles,” said Winnie-the-Pooh, and Piglet said that anyhow he had nothing to do until Friday. So off they went together.</p>

#info h3{ text-align:center;
}
#holdit {width:700px; position:relative; margin:3em auto; padding:10px; border:1px solid #ddd;}
#holdit img {position:absolute; z-index:1; top:10px; left:10px; }
#holdit p { margin:0px; position:relative; z-index:10; line-height:18px; text-align:justify; font-size:10px; font-family:verdana, arial, sans-serif}
#holdit em {display:block; float:left; height:18px; clear:left; overflow:hidden; }
.a230 {width:230px;}
.a240 {width:240px;}
.a250 {width:250px;}
.a270 {width:270px;}
.a300 {width:300px;}
.a340 {width:340px;}
.a360 {width:360px;}
.a370 {width:370px;}
.a400 {width:400px;}
.a420 {width:420px;}
.a430 {width:430px;}
.a460 {width:460px;}
.a490 {width:490px;}
.a500 {width:500px;}
.a540 {width:540px;}
.a550 {width:550px;}

　　接着我们来分析一下红色加亮的部分:

　　首先将包容对象#holdit设置成相对定位(确保等下的img绝对定位以它左上角为原点)

　　接着把#holdit里面的img设成绝对定位且z-index高度为1，这样img就脱离文档流了

　　将em标签设置左浮动，高度和p的ling-height要一样，再根据图片的图案分别设置每个em的宽度(记得要用clear来清除浮动)

　　最后把P设置成相对定位且z-index高度设置大于img的数值

　　其实我们也可以直接将图片作为为#holdit的背景，这样就不需要专门为img来设置CSS了
