Are temporarily hidden elements bad for search-engine rankings?
I'm creating a FAQ for my page. To help the user to get a better overview I want to hide all answers and only display the questions. If the user clicks on a question the answer is set to display:block.
I know that google also reads and indexes hidden content, but I also know that hiding text is a common technique for spammers and thus probably discredited by google, resulting in getting wiped from search results.
But I'm wondering; Does google always downrank pages that have large amounts of hidden text? Does Google have some kind of intelligence? I mean an FAQ like this is not that uncommon. Should I not use this kind of FAQ?
