A beautiful Drupal 8 one page theme. There is more than one page possible. The home page is mostly one page and the rest is normal. The structure of these kind of themes have a lot of blocks. Every block has his own CSS and structure. A view for example is being showed in responsive divisions, if the teaser mode is used. Ideal for showing pictures. Be ware that you use the teaser mode. All other modes are showed in the usual way.
As there are many blocks and configurations, one page themes need a lot of Drupal experience... See also the English tutorial for the details.
