Adobe XD in User Interface/User eXperience (UI/UX)

During UI/UX lesson, we learnt on how to create websites for electronics devices on Adobe XD. The issue that I am having is that sometimes the things which I am trying to do to make it similar to the real websites is different from what I wanted it to goes. I tried to solve it by redo the things again and it works after a few tries. I am also able to create a phone which have everything inside my phone.
