css属性 overflow-y:auto; DIV里面的内容超过DIV的高度，右边就会自动出现滚动条

1、用一个div，定制成图中的宽度和高度
2、然后再把div的样式设成overflow-y:scroll，当div里的文字超出那个高度的时候，滚动条就出来了。
例如：<div style="width:100px; height:100px; overflow:auto; border:1px solid #000000;"><img src="" style="width:300px; height:300px;"></div>

要么就直接加一个系统默认效果的滚动条，overflow-y:auto;记得div要设置高度；
如果不喜欢系统默认的滚动条，那你可以做一个模拟滚动条，我直接发一个示例给你，你自己对照修改，我想会css的人修改应该不会有问题

不会CSS 可以讲得具体些吗

追答

不会css那就有点麻烦了，需要改的css代码太多，也没法说得具体，给你的只是实例，就相当于给你原理，你得根据原理制作；搞不来模拟滚动条的话就用默认滚动条吧，因为滚动条用css直接换样式的话兼容性不好，所以你还是直接用最简单的默认效果好了，在你需要加滚动条地方加overflow-y:auto;并设置高度，例如：

注：100px是宽度，200px是高度，你根据你自己的部分设置相应的高宽即可

给div加,给一个简单额例子给你

<div style="width:100px; height:100px; overflow:auto; border:1px solid #000000;"><img src="" style="width:300px; height:300px;"></div>追问

这个要加载什么位置哦

第3个回答 2013-03-27

用一个div，定制成图中的宽度和高度，然后再把div的样式设成overflow-y:scroll，当div里的文字超出那个高度的时候，滚动条就出来了。

第4个回答 2013-03-27

css属性 overflow-y:auto; DIV里面的内容超过DIV的高度，右边就会自动出现滚动条追问

问题是不是要最右边出现滚动条，而是中间白色的框里面出现一个滚动条啊

追答

你的内容是写在DIV中的吧，在DIV设置这个属性，固定高度，超出DIV就会出现滚动条，而不是页面最右边，还可以设置overflow:scroll;滚动条始终出现，在哪个DIV设置，那个DIV就会出现

追问

好的我去试试
