For a place in my website I need to create something that is not bootstrap related. 3 Columns using Flexbox. I have created one Div element (the Row) + 3 more Divs (columns) inside of it. I have assign a custom class for the Div Row (3-cl-container) and when I try to add css to it, nothing actually happen.
I am also not able to select the new class I have created through the Style Attribute dropdown.
Also if you look in the components list under UI > Structure you’ll find there is a component already built to do the 3 col row. Might save you some time pulling your hair out
