Why are the styles in the component being ignored?

Question

Vue.js

When specifying styles that already exist in another component, they are ignored, although logically they should be overridden. This happens if you set scoped styles.
Tried to set through a unique class, did not help.

Answer 1

The answer is found in the documentation.
in my case, you need to write / deep / before each nested class and everything will work.
