Parent to child partial inheritance

Hello! I am quite new to ionic and therefore my question may seem a bit strange. The problem i am currently working on is how to show a particular html element (div in my case) of a parent to a certain amount child elements. I have a few tabs and i need only one tab with its children elements to inherit certain html. Another possible solution for that could be creation of another parent element, but then js code gets quite messy.
I’d be grateful for any advice.
