How do I add class or ID to sprites?

Hello, I'm a french beginner on construct 2 and I wanted to know if some of you guys, know how to add ID to a sprite. Indeed, i'm not making a game with construct 2, but a presentation like powerpoint does. So I would like to add some css effects(bounce, fade, etc...) to my photoshop pngs that i've imported to construct 2.

Sincerely

I don't think it's possible. You can do Fade, bounce and other effects with Construct behaviors.

Yes, but I've seen a video of someone showing his finished work on an index.html with elements that have css property as graphic bar which goes up and down, hover effects ans so on...

maybe these are just buttons with ID...can the buttons image be replaced by an imported png ?

You can assign ID and change CSS properties with "Form controls" objects (button, text box, progress bar etc.) But if you are planning to add just these objects to the layout and then control them from external scripts, this would be a very weird use of Construct.
