The structures 就算…也… and 就是…也 have the meaning "even though..., will (still)...".
In these structures, we should put a verb or a phrase in place of the ellipsis.
Examples
物质条件就算再艰苦也无法难倒我们
No matter how difficult the financial situation is, we will not give up
If a sentence has one subject, it can be placed either before or after 就.
If a sentence has two subjects, the first subject is placed after 就是/就算 and the second subject is placed before 也.
