Here is a link to the official documentation for creating custom content types and new content. Link: https://developer.salesforce.com/blogs/2019/11/use-the-cms-app-to-create-content.html

As per the documentation you could use the below endpoint to fetch details about an existing content type. However, i was not able to find the {your-contenttype-id}. If you find a way please comment it here

Salesforce CMS (Content Management System) allows you to manage content documents.

A content type allows you to define the fields for a content. For example you could have blog posts, faq, how-to-article etc as content types. The below post describes how to create a new content type since this cannot be created with the Setup customization.

Use the workbench to create a new content type. A new content type allows you to define the fields for your content.

Endpoint:
/services/data/v47.0/tooling/sobjects/ManagedContentType/

Request Body:

Note that the 'isLocalizable' attribute determines if this field can be translated or not.
 


The data type of the field that be created is mentioned here. https://developer.salesforce.com/docs/atlas.en-us.api_meta.meta/api_meta/meta_managedcontenttype.htm (Check the nodeType entry in the table)

There are several ways to handle apply custom styling to your lightning components. This link gives you an overview of these approaches.

While using the component CSS file, i ran into an issue where the custom styles were not applied to a lightning component. On further analysis, it appeared to be depending on the way the CSS class definitions are declared in the CSS file.

Below are two types of declarations of the 'custom-button' class, the first one without spaces and the second one with spaces. In some cases the first one works, whereas in other cases the second one works. I have still not figured out the reason for this behavior. To debug similar issues just add/remove the spacing and observe the behavior.





As a best practice, you might want to tie your class to the selector to be more specific. The below example ties the class 'fancify' to the html element label.
