Hi,
I had want to change the colors on the button classes so wanted to add that to my custom.css file but when it did work I use Inspect and can see that it is being loaded before a few sp page builder .css files.

Just wanted to see if that is expected behaviour as i would have thought that custom.css would be loaded last.
Cheers.. I am still using SP PB 3 btw
