+Feature: Access document styles
+  In order to discover and manipulate document styles
+  As a developer using python-docx
+  I need a way to access document styles
+
+
+  @wip
+  Scenario Outline: Access document styles collection
+    Given a document having <styles-state>
+     Then I can access the document styles collection
+      And len(styles) is <style-count>
+
+    Examples: having styles or not
+      | styles-state   | style-count |
+      | a styles part  |      6      |
+      | no styles part |      4      |
+
+
+  @wip
+  Scenario: Access style in style collection
+    Given a document having a styles part
+     Then I can iterate over its styles
+      And I can access a style by style id
+      And I can access a style by its UI name
