Container
When you create a container, it’s a whole other section. It’s separate from other containers and columns. This will come in handy when you have different sections on your page, and you need to organize what information is in certain sections. You should always name your containers so you know what is in them.
Columns
When you create a column, you are adding column(s) into a container. Columns cannot be renamed, or are viewed as a separate area, like a container. You cannot organize columns into separate sections. Columns help embellish a container.
