Dear @KingJut
There would be a difference based on what is needed.
Do you scroll and then i get's smaller once, E,g
Top of page > Logo=100px
25% down page > Logo=50px
Or does it shrink gradually in relation the the specific scroll E.g
Top of page > Logo=100px
1% further down > Logo=99px
1% further down > Logo =98px etc
This would need to be custom coded by you, adding the code within > Lay options > Custom CSS & HTML >

For targeting the site title has a class called sitetitle
E.g
.sitetitle{
// insert CSS here
}
