Apply styles in C# scripts

In a C# script, you can set styles directly to the style properties of a visual element. For example, the following code sets the background color of a button to red:

button.style.backgroundColor = Color.red

You can also add a Unity style sheet (USS) to any visual element. Unity represents USS files as StyleSheet objects in C# scripts.

To add style sheets to a visual element:

  1. Load StyleSheet objects with standard Unity APIs such as AssetDatabase.Load() or Resources.Load().
  2. Use the styleSheets property of a visual element to add the StyleSheet object.

For example, given a style sheet in the local variable styleSheet and an element in the local variable element, the following example adds the style sheet to the element:

element.styleSheets.Add(styleSheet);

Note: Style rules apply to the visual element and all its descendants, but don’t apply to the parent or siblings of the element. Any change to the USS file automatically refreshes the UI that uses this style sheet.
