+Classes can also be given a special relation type that defines a lollipop interface on the class. A lollipop interface is defined using the following syntax:

 #### Classes
 
 More convenient than defining the style every time is to define a class of styles and attach this class to the nodes that

+should have a different look.
+
+A class definition looks like the example below:
+
+```
+classDef className fill:#f9f,stroke:#333,stroke-width:4px;
+```
+
+Also, it is possible to define style to multiple classes in one statement:
+
+```
+classDef firstClassName,secondClassName font-size:12pt;
+```
+
+Attachment of a class to a node is done as per below:
+
+```
+cssClass "nodeId1" className;
+```
+
+It is also possible to attach a class to a list of nodes in one statement:
+
+```
+cssClass "nodeId1,nodeId2" className;
+```
+
+A shorter form of adding a class is to attach the classname to the node using the `:::` operator:
+
+```mermaid-example
+classDiagram
+    class Animal:::someclass
+    classDef someclass fill:#f96
+```
+
+```mermaid
+classDiagram
+    class Animal:::someclass
+    classDef someclass fill:#f96

+        -int sizeInFeet
+        -canEat()
+    }
+    classDef someclass fill:#f96
+```
+
+### Default class
+
+If a class is named default it will be applied to all nodes. Specific styles and classes should be defined afterwards to override the applied default styling.
+
+```
+classDef default fill:#f9f,stroke:#333,stroke-width:4px;
+```
