Page using a lot display: flex, position: relative and absolute

It took me 1 month to finish this project. Good thing we have display flex to save our lives. In some cases I had to use position: relative and absolute to position some elements on the screen. I think I overdid it when putting the percentage measurements to define the widths of the elements and that compromises when it comes to responsiveness. The right side of the project is not aligned vertically. I still have a lot of doubt about how to position certain elements. But with constant practice, we will win.
