It seems no matter what animation delay I put on an element, it does not take effect. Looking through the bricks.js, the only code I see related to delay is for the Content Loaded trigger so I suspect this may have been overlooked.
Somewhat related – when setting the trigger to Content Loaded, delay only works with whole numbers and not decimals. So if I wanted to stagger the animation of 3 columns, the minimum I can put is 1 (second) as .1 - .9 don’t do anything.
