I have a grid with 3 rows with three containers with 33% width in each row. It worked perfectly – untill today I found that it is distorted, and I find no way to fix it. There was an update yesterday of some plugin generatepress, so I think it has to do with that update? https://honigwerk.de
(I have fixed it now, there was a global style set, that broke the layout, I had to redesign without this global style.)
