Twinkling when hovering

Hello World !

Is there a way for me to have images of my landing page to “twinkle” when hovering, kind of the same way my “Rush to the Store” text at the bottom of my landing page does ?

Same, is there a way to make the images appear from the side, for example, or just to appear, as we scroll down on the landing page ?

I wish you a nice day !
