Finally, I did it. After six years I relaunched my website with a new look and a fresh blog design. I switched from the cms modX to wordpress while using the Septera theme. I wanted to save a lot of creation time with it. Nevertheless it took a while until everything was working like intended. Having a wordpress installed is super easy but having your landing page correcly showing and in a layout and design you want not. But in the end I understood how wordpress and the theme are constructed. With some custom css additions I even added the nice background video where normally a static image was placed.
