This is the beginning of learning WordPress using the Divi 4 template. Working visually, by copying a pre existing great design is a good approach. Compared to my previous experience this sound like fun. Although I learned a lot about setting up WordPress locally then using hosting plans I barely learned design due to my preoccupation with technical implementation. 

chosing a template to copy manually and methodically with the purpose of learning what goes into a design is actually a smart move since the inspiration and the solutions are already there
