Targeting banner images for fade-in on scroll

Site URL: https://gregorylassale.com/

I use a fade-in effect to reveal elements on scroll but can't get it to work on banner images.

Right now I'm targeting the following:

.image-block,.summary-item,.sqs-gallery img,.html-block,.sqs-block-button,.sqs-block-content'

What is the class selector for banner images?  I tried to inspect on Chrome, tried a few things but can't get banner images to fade in. 

I'm on Brine / 7.0.

Thanks. 

Hi. Do you still need help on this?

Where is banner? Can you take a screenshot?
