How to use Titanium app.tss in classic mobile app

I want to create a stylesheets for my Titanium app. I'm not using Alloy framework, so how i can use app.tss? in which directory i need to store it?

Thank you

You can't.

.tss files are features bring by Alloy. However, if you want to use custom styles, you may have a look to the applyProperties method.

You can maybe do some workaround like this :

// Create window object
var win = Ti.UI.createWindow(),
    label = Ti.UI.createLabel();

// Create or import properties
var properties = {
    window: {
        backgroundColor: "#1DB7FF"   
    },

    label: {
        text: "I Love Titanium",
        color: "#FFFFFF"
    }
};

// Apply properties
win.applyProperties(properties.window);
label.applyProperties(properties.label);

// Build views and launch
win.add(label);
win.open();
