How to build a layout using the column feature
The modules container and the modules itself have built-in a "column" feature which allows you to build multi-columns layouts.
Please check the next screenshots to see where you can find this feature.
All the columns are left floating. On responsive devices, according to the device screen width, these columns will be displayed using this CSS rule. In order to have a more control over the order of the columns ensure that you are using properly the containers. Avoid the usage of all your page modules in a single container.
