Hey,
I'm using Montezuma theme and I switched CSS grid to 100%. Now, when I select a picture for a post, it is shown on my main page. But it is shown on the left and I want it in the center of the picture box. So, in .post-thumb img in posts.css, I added margin-left: auto; margin-right: auto; . But this doesn't change anything.
What do I have to change that it works?
