To inherit or not to inherit properties in scss?

Question

css

Using sass, the question arose, to inherit or not to inherit?

<div class="block">
   <div class="inner_block"></div>
</div>

Option 1:

.block {
   // свойства
   .inner_block {
      // свойства
   }
}

Or option 2:

.block {
   // свойства
}
.inner_block {
   // свойства
}

The question is about two blocks that are essentially unrelated to each other.
I don't mean the link inside the block.

Answer 1

For example, I inherit. Since it is not known whether you will have another such block, with the class

.inner_block

for other purposes. And in such cases, I inherit this class from the parent.

Answer 2

Of course, I'm not hinting at anything, but ... "To use or not to use sass?".
And yes: perhaps we are talking about scss.
