Custom Framework configuration 

If you don't use Bootstrap or you need to customize the prepared grid ratio then you have to change the grid.json file. Following steps will describe how to do it.

Copy Grid.json 

Copy the Grid.json to your resources folder. The Grid.json is located in: Resources/Private/Grid/Grid.json

Make your changes 

Make your changes in your own Grid.json file.

            "class": [
                "",
                ""
