How to style a template grid

Hello, I have 2 questions about styling a template grid that I was hoping to get answered. The first being how can I add a space between the items of a template grid so they are not touching each other. The second question I have is how can I change the background color of the item I select in the template grid meaning when I click on it, the block will change color other than the standard grey color how can I make this color say blue?

Hi Samuel,


there are a lot of different ways of customizing elements within mendix.

I would advise doing a codeacademy tutorial, and looking into the custom variables in the theme folder in your project directory
