What is the difference between dark romantic literature and Gothic literature?

[goths]

hey everybody,
i have a crucial question,perhaps even stupid,but be patient with me please
so the question is: What is the difference between dark romantic literature and Gothic literature?
i don't see any difference, especially when knowing that gothic literature appeared during the romantic period ,so i think it is normal also to call it "dark romanticism" ,am I wrong?

i found this answer on WikiAnswer but i still don't see the difference:
