By clicking Add on the side bar, then on Containers there are some smart ways to add content to your website in a contained way. For example, if you want a box containing an image and piece of text, first add the container, then add your image and text box - this box now has the text and image anchored to it, wherever you move the box, the text and image goes to. Not only is that quite nice when editing, it is also nicer behind the scenes in the website code, when a user now views your website on a smaller screen, the background box will justify correctly and still display the image and text how you defined it to.
The second nice feature with containers in the ability to tabulate them. Again in the Add > Container menu, select Tabs. With this container you can set up a series of different bits of content to display in the box, then you can set up how you want to transition between those different pieces of content. Providing a scenario may make its function clearer, lets assume you are wanting to display 3-4 different products you sell. Rather than displaying all of the images at once, cluttering up valuable website space you can add each image to a tab of a container. Once all 3 images have been added you can choose how you want users to move between them, to do this select the container, click Settings on the tools palette and click Tabs Transitions.
Here you are able to change the animation between each tab, how long that animation takes and if you want the animation to occur automatically, i.e. without the user having to trigger the tab change.
