Is floating block allowed in adsense?

Question

css

For example, in the sidebar - what would a banner with an advertisement be shown when scrolling down?
Something like 300x600 =)

Answer 1

I read somewhere that this is prohibited, such as the user's emphasis on advertising

Answer 2

if there is high-quality traffic, there is a lot of it, there are conversions from the stack block, then Google turns a blind eye
