System Drupal 7 becomes deprecated, so I working on migration of all my web sites to newer Drupal 8. Now I managed to upgrade the web of housing association made in the year 2015. There is a lot of incompatibilities in the new Drupal version, so upgrading it means to create also a new theme and replace few deprecated modules.
New theme is based on the default Drupal theme named Bartik. Main colors remains the same shades of orange, but I added a new plum violet accent color. These colors look great together, one is derived from color of the house facade, the second one is derived from the street name - Slívová (Plum street in english).
I also made a new logo for the web. It is a plum and it has an address number on it.
