在框架集中重叠 Collapse/expand 内容

Question

如何重叠框架集中的 collapsed/expanded 内容显示（我不想缩短顶部框架的细节）？我使用一个 3 框架的框架集（顶部框架、左框架和右框架），并且无法使这个东西工作（为重叠顶部框架集中的扩展内容而制作的脚本，类似于 z-index 逻辑）。是否可以进行此更改？请给些建议。谢谢

当前系统布局的屏幕截图。

但是当我点击展开 link 时，所有顶部框架的细节都会被缩短。如何使展开的细节布局与顶框重叠？

"please give some advice"

Stop using frames: they are not supported in HTML5.

Use tables when you need a table. Do not use tables for layout purposes.

Always specify a docytpe.

Use lower case for the HTML tags (or upper case if you want, but don't mix them)

Take this list as a recommendation and not as criticism. I made those mistakes too.

正如您在问题中提到的，这可以通过 z-index 解决。您面临的问题可以通过使两个 table 具有绝对位置（与 top-left 对齐），并给第一个 table 一个比第一个 z-index 更高的 z-index 来解决第二个 table:
