Hi all! OK - I'm in the newest Squarespace version and trying to do what everyone else is... want my home page gallery to switch to color from b&w (over 1 second). Hoping this applies gloabally to the entire website. Oh - and any specific support around where to implement the CSS would be helpful. I'm just dumping it under "Design" and "Custom CSS." Perhaps I should do it elsewhere? None of the above code sections worked for me.
