I cannot see what you have done based on the HTML code, so I cannot tell you exactly what to do.
But depending on how you have implemented the animation you can use (for example) the opacity to make the objects initially invisible.
Pablo give good instructions, link etc. but you not good doing, this logos not have event, that is simply animations, so that can add double click at image
and add in animation fade down. Circle yellow can be event or transitions to work at hover to be bigger, that when with mouse logo goes left-right - that is script
I also thank you for your positive directions. I believe I will somehow overcome the problem. now on mobile, the background does not fit on the screen I did not understand this, I used 480x560x980x1024x1280x1920 as breakpoint. I don't know my phone model LG V30 +, I have the same view on your mobile device, but I have to overcome it. I am waiting for your ideas and guidance again. Best regards.
