Style properties consist of two parts, a prefix that specifies when the property is used, and the property itself. For example, a button's ``hover_background`` property is used when a button is focused, while its ``idle_background`` property is used when the button is unfocused. (Setting the ``background`` property sets the ``idle_background`` and ``hover_background``, among others.)

4.

While Ren'Py has over 100 style properties, only a few properties are used in this section. Along with ``background``, we use ``color``, ``font``, ``outlines`` and ``size`` as style properties. For a full list of style properties, please read the :ref:`style properties <style-properties>` documentation.

Using Styles and Style Inheritance

6.

Each displayable has a style built-into it. When the displayable is created, either directly or using the screen system, style properties can be supplied to it, and these styles are used to update the look of the displayable. In the following example::

7.

the :propref:`size` property is supplied to a Text displayable, allowing us to change its text size. This will customize the look of the text displayable by displaying the text 40 pixels high.

8.

Similarly, when using Screen Language, each user interface statement takes relevant style properties::

9.

Ren'Py supports style inheritance, with each style having a single parent. If a style property is not defined in a style, the value of the property is inherited from the closest parent, grandparent, or other ancestor.

10.

Each displayable takes a property named ``style``, which gives the parent of the displayable's style::

11.

When no ``style`` property is given, a parent is chosen based on the kind of displayable be that has been supplied. The parent chosen can be influenced by the :ref:`style_group <style-group>` property of user interface statements in the screen language.

12.

When a style is defined without a parent being specified, a default parent is chosen for the style. If the style contains an underscore (_) in its name, the parent is named by removing everything up to and including the first underscore. For example, a style named ``my_button`` will inherit from ``button``. This inheritance can be changed using the style statement or by calling a method on a style object. When a style that does not exist is used, and the style has an underscore in its name, Ren'Py will create it using the default parent.
