I think, its a quite common mistake in programming world but its okay it happens with everyone. All I can say to you, use Frontend Mentor website for practicing more UI rich templates, you'll also find others solution there, so even if you stuck at some point you'll able to read someone else code and understand how they have implemented. As a developer I can guarantee you that you'll learn a lot once you starting reading and understanding other developers code. Happy Coding ⚡
