Add & Edit Dialogs
Concrete CMS's edit interface makes heavy use of the Bootstrap 3 user interface toolkit. This special build of Bootstrap namespaces its CSS classes within the "ccm-ui" class, but block developers don't have to worry about including this class in their HTML. This is automatically included in the dialog window. Bootstrap isn't required – any markup will likely work in a block dialog, but it does create nice looking forms. The Hello World Block uses some basic Bootstrap styling.
Inline blocks that include their own toolbars should use the "ccm-inline-toolbar" on a UL element to create this toolbar. This will ensure that the toolbar affixes to the top of the browser window.
Nothing special is necessary to style a block's view.php. To repeat: nothing special is necessary! In general, a best practice is to use classes that begin with "ccm-block" and then use the block's handle. For example "ccm-block-page-list-title" and "ccm-block-topic-list-wrapper." This isn't required.
