我正在开发一个 JSP 站点。
我有 3 个主要的同心 div:
- “容器”(包含整个站点)
- “内容”(包含内容)
- “results”(在“content”里面，包含大量服务器生成的数据)
我设置了 CSS，以便当大量数据存放在 div“结果”时，水平和垂直滚动条会自动出现。
成功了。
直到我将这些标签添加到页面顶部以解决其他一些不相关的问题:
<!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">
我尝试了下面第二个答案中的建议，在 div 中设置高度。没有快乐，即使我用 px 设置高度。如果可能，我需要使用 %s 设置高度。
我对麻烦的 JSP 进行了屏幕保存，取出了所有与问题无关的垃圾，并将 CSS intp 置于头部以简化问题的调试。下面的引述是一个 HTML 文件，您可以将其放入浏览器和文本编辑器中亲自查看问题。粉红色的 div“结果”只应与 stackoverflow 编辑框一样高，并根据需要显示水平和垂直滚动条。

最佳答案
你确定你没有按照我说的去做吗？我刚刚将您的代码转储到我的浏览器中，并进行了更改
#results
{
height: 40%;
}
到
#results
{
height: 200px;
}
粉红色框的行为符合我的预期和您的要求。
关于使用 % 而不是 px:除非您为容器设置固定高度，否则您不能。
关于html - 当溢出设置为自动时，不再出现垂直滚动条，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11023270/
