font face and size in GUI box

I have put out this bit of code to make a standard text box but cant figure out how to format it, i want to increase certain sizes or the text, change to bold etc. Is this possible as the reference manual didnt’t leap it out to me.

function OnGUI() {
     GUI.Box(Rect(100,80,483,200),"f");

You have to create a new GUIStyle as a public var in the script, then pass that GUIStyle to the GUIContent of the GUI.Box. Then you can edit the display properties of the GUIStyle in the inspector pane of the editor.

Something like:

public var customGuiStyle : GUIStyle;

function OnGUI(){
	GUI.Box(Rect(100,80,483,200),"f", customGuiStyle);
}

See Unity - Manual: GUI Style (IMGUI System) for more info.

great, thank you
