Hi there,
I am using Avenue template and want create black and white to colour rollover thumbnails on the 'Project' page (https://sapphire-wedge-gkn5.squarespace.com/config/design/template). I have looked at a few tutorials, and most mention 'Gallery Styles' for image grids under Site Styles. But this option does not appear in Avenue.
I would really appreciate some help.
Thank you 🙂
