Mr. Usborne, thank you very much, I really appreciate your help.
Could you complete the trick?
If I do a search with this CSS activated, the brick containing the word(s) sought after is a bit bigger than the rest of the masonry posts. It fills all the space, ignoring the new margin that is set at the right.
The same behavoir happens when you open a normal page of the site (not a post)
I’m sorry I don’t have the skills nowadays to identify those items in the PHP files to add them to the CSS by myself 🙁
