InnerClassName prop

[Mohammadreza-Sarvari]

next and previous click ranges are 50% of page. when we want to decrease their width based on out needs, we should define a wrapper for Stories component and set a class to this wrapper to access next and previous div, like this:

.story > div > div > div:last-child > div:nth-of-type(2) {}
.story > div > div > div:last-child > div:nth-of-type(1) {}

So, I think, if we define a class for parent of them, we can set styles easier.
