javascript - Adding margin to an element in vue2.0 reports an unexpected "indentation" error?

Question

An error is reported after adding margin, why? How to solve it?

Answer 1

With all due respect, I can’t see the error message clearly

Answer 2

The picture is so small, I don’t even know what the title is.

Answer 3

I’m not familiar with stylus, but I see that the syntax is similar to python, both relying on indentation
In addition, the error reported is unexpected indent
It should be that spaces and tabs are mixed together
It is estimated that the previous code used spaces, and the newly added margin You must use tab indentation
