Pages, Areas, Blocks, Themes and Stacks
A block is some content or functionality you can edit from within a page in concrete5. Think of legos, these are the actual building blocks that go together to make the pages of your site. There are many types of blocks. Your concrete5 install comes with some basic blocks including the Content block, Survey, Conversations, Image Slider, etc. You can find more blocks, both free and commercially supported in our marketplace.
Themes set the overall look and feel of your concrete5 site. Themes are presentation focused, and control how your content is presented. Themes can be applied to an entire site through the Dashboard's Themes page, or applied to just a single page (mouse over the Edit icon in your editing toolbar and click Design).
Stacks let you reuse a block or a combination of blocks in multiple places on your site. From this Dashboard page you can manage all the stacks you have permission to access. The Global Areas Stacks are the stacks that appear on every page of your site. The Other Stacks were created by users. When you add a Stack it will be added in the Other Stacks.
