Add block » Advanced » Container

Containers are used to define and contain the various sections of your page in the building tool. You can then add other blocks or more containers inside the container. To add content or another container below the current one click the + beside the container name block. In the html code of your page they create
<div class= "xt_container" data-xtcontainer="container name">......</div>
The
data-xtcontainer="container name" is what tells the building tool to create the block as a container. You can set the name of the container (This shows in the building tool). The css class"xt_container"is assigned to the container by default. You can add a second class to add more styles to the container and these must be defined in your global_stylesheet.css file or with the page css editor from the building tool. There is also an alignment parameter to hold the basic "text-align" for the container.
NOTE: If You Delete A Container, ALL The Blocks It Contains Are Also Deleted. The container names header navigation gallery are reserved and will create containers with the class
xt_header
xt_navigaton
xt_gallery
with special add navigation item or add gallery item blocks. Mobile users have the option in panel » settings » look and feel to collapse the content of containers in the building tool to save space just the blocks in the container will be listed when you open it.
