Usually you should be able to create a div tag that wraps around your image/text with your own class name in your rich text, then follow it with the CSS that targets the div tag class name you created. So instead of targeting a glide object, you are targeting your own object. I don’t exactly have a ready example, but I’ve done it with html tables in my app and then added some extra styling. I’ve also done it with some animations that are controlled by by sheet data. There’s probably a few other example somewhere in the forum.
Take a look at how I added the clock in the app in this thread. It’s animated and within a rich text component. I don’t have an action on it, but I could if I needed. I think that will give you a general idea of what I’m talking about.
