Show/hide element based on current blog post category

Hi there,

I would really appreciate any help please, I must be missing something silly, but I’ve tried many forms and couldn’t reach what I need. Does anyone have any idea on how to show/hide or collapse/expand an element (such as a simple box with the id #box1 ) on a Blog Post page based on the current post category? Like for example I want #box1 to show when the post is on the Cuisine category, but I want it to hide and show #box2 instead if the post is on the Tourism category.

Sorry if it’s silly, but that’s the last thing I need to get what my client needs perfectly :smiley: Thanks in advance!
