我的尝试：



母版页内容

What I have tried:

master page content

<div>

</div>

推荐答案

我在这段代码中没有看到两个div。除了强制换行之外，div不会做太多（如果你有两个div，它们会在不同的行上）。除非你有奇怪的CSS，你所说的不可能发生，而你的代码不是你所谈论的例子。



ASP.NET已经淘汰了十多年。如果你只是在学习，我建议你学习别的东西。如果您正在维护ASP.NET现有系统，您实际上可以在MVC中运行ASP.NET，在MVC中构建新页面，并在ASP.NET中使用旧页面

I don't see two divs in this code. A div doesn't do much besides forcing a new line (if you had two divs, they would be on separate lines). Unless you have weird CSS going on, what you're saying can't happen, and your code isn't an example of what you're talking about.

ASP.NET has been obsolete for over a decade. If you're just learning, I suggest you learn something else. If you're maintaining an ASP.NET existing system, you can in fact run ASP.NET inside MVC, build new pages in MVC, and have your old pages in ASP.NET
