After setting the nature of your content type, the next step is to add fields to it.
Fields are the building blocks for structured content. The type and order of the fields that you add to a content type decides how the content will be finally presented. For instance, while creating a content type for a “News Article” page, you may add fields such as "Title," "URL,"' "Date," "Body," as seen in the following screenshot:
All the content that you will be adding to create an entry actually goes into fields.
Note: In a particular content type, you can add at the most 100 fields.
Fields are of various types, designed to handle the most common content input needs. Each field type determines the type of data it can store. An example of a field type is the Number field type, which accepts only numeric characters. Similarly, there are several other types of fields that you can use in a content type.
Each field possesses certain properties, such as “Display Name,” “Unique ID,” “Default Value,” “Help Text,” “Mandatory,” and so on. These properties are editable, providing flexibility to customize the nature of the field.
