Divi is a wonderful framework that lets you build sophisticated websites via drag & drop. There are also plenty of decent extensions and child themes available for it. Take Memento for instance: it is a portfolio and resume theme for Divi powered websites. It has dark and light skins.
This theme has 3 light and dark modes. It has a responsive, clean design, so it looks great on mobile devices and desktop computers. Memento not only lets you display your portfolio but also testimonials and services. Your visitors will be able to view your work and get in touch with you with their questions. Designpik is the designer behind this theme.
