Spotted a bug !
EDIT: moved preformated code out of summary as a workaround so bug doesn’t show anymore.
Wow, I’m currently exploding my average delay of posting on this blog. Once posted, I’ve noticed that the theme layout currently used with Zola (blow, not to name it) is broken with preformated content when you look at the sum up list of posts. Given I’m not much (read at all or so) into CSS, front-end and such, that may be fixed one day or another. Either by fixing blow or using another Zola theme. That’s it for now, you can resume your normal activities.
