Creating and editing content blocks
You create content blocks when you need to display various kinds of nonspecific information (all information different than the predefined content types, such as news or event announcements). Content blocks are very useful when you need to create text that will be used on many pages of your website. For example, company address.
You manage content blocks on the Content blocks shared across pages page.
To open the page, in the main menu in the upper part of the screen, click Content » Content blocks.
The Content blocks shared across pages page appears, displaying a list of all created content blocks together with actions you can perform on them.
Use this page to create, edit, and manage shared content blocks, which you can then reuse on as many pages as needed.

On this page you can do the following:
Displaying content blocks on your website
To display content blocks on your website, you must use the Content block widget and you must configure it.
For more information, see Configuring the Content block widget.
For more information about adding widgets on your page, see Adding widgets on your page.
You can then choose the way blocks are displayed by changing the template which the Content block widget uses.
