[Grammar] "Opposite of something" or "opposite something"

[fruitfly]

Hello. I have a question about grammar.
When do you use "Opposite of something" or "opposite something"?
I cannot think of an example for each one at the moment, but I remember reading a sentence in a textbook that said "something is opposite something".
I've always used "opposite of something", so I'm not sure why/when the latter one is used.

White is the opposite of black.
My house is opposite the post office. (= directly in front on the other side of the road)

Thank you for your fast reply. So is "opposite something" used for pointing out location? And is "opposite of something" used when there are two opposing concepts?

Yes, that's it, with my addition.

There may be something other than location where you can say "opposite something". I can't think of one right now but you should keep an open eye on it.

You can use it in something like opposite counterpart, which is not physically a location.
