If you want to add style to more than one control, use a GUI Skin instead of a GUI Style. For more information about UnityGUI, please read the GUI Scripting Guide.

Please Note: This page refers to part of the IMGUI system, which is a scripting-only UI(User Interface) Allows a user to interact with your application. More info
See in Glossary system. Unity has a full GameObject-based UI system which you may prefer to use. It allows you to design and edit user interface elements as visible objects in the scene viewAn interactive view into the world you are creating. You use the Scene View to select and position scenery, characters, cameras, lights, and all other types of Game Object. More info
See in Glossary. See the UI System Manual for more information.

Details

GUIStyles are declared from scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary and modified on a per-instance basis. If you want to use a single or few Controls with a custom Style, you can declare this custom Style in the script and provide the Style as an argument of the Control function. This will make these Controls appear with the Style that you define.

First, you must declare a GUI Style from within a script.

/* Declare a GUI Style */
var customGuiStyle : GUIStyle;

...

When you attach this script to a GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary, you will see the custom Style available to modify in the InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary.

A Style declared in a script can be modified in each instance of the script

Now, when you want to tell a particular Control to use this Style, you provide the name of the Style as the last argument in the Control function.

...

function OnGUI () {
    // Provide the name of the Style as the final argument to use it
    GUILayout.Button ("I am a custom-styled Button", customGuiStyle);

    // If you do not want to apply the Style, do not provide the name
    GUILayout.Button ("I am a normal UnityGUI Button without custom style");
}
Two Buttons, one with Style, as created by the code example
