Adding Containers to Media Queries
After you define a media query string, add the container or containers to which to apply the media query. After you add the containers you can modify them as necessary for the query.
To add containers to a media query:
Access the Select Classes for Media Query page.
SelectThe Template Designer page appears.
Click the Media Queries tab. The Media Queries page appears.
Click the Create Media Classes link.
All the containers defined for the template and that are not yet assigned to the media query appear on the page.
Select the container(s) to add to the media query.
Click the Create Classes button.
Click the Save button.
The Media Queries page appears and the container(s) you selected appear in a Containers grid at the bottom of the page.
You can now modify the containers defined to a media query without impacting the base container definition.
