Tailwindcss will have no effect when srcDir is set to an external directory of the current working directory

[ajiho]

Describe the bug

I raised an issue about the Tailwindcss style not being effective before.

With the enthusiastic help of Vitepress team member brc-dd, I solved this problem.

But now we have encountered a very tricky problem

Expected behavior

Even if srcdir is set outside the current working directory, tailwindcss can still function properly

I have tried to modify the content attribute of TDconfig, but neither absolute nor relative path works

@brc-dd Can you help me take a look? Thank you.

The problem has been resolved, I have decided to close it

What was the solution? Moving tailwind config to outside-src? (You can probably configure tw config path in postcss config too 👀)
