from kivy.app import App
#kivy.require("1.8.0")
from kivy.uix.floatlayout import FloatLayout

class SimpleKivy4(App):
    def build(self):
        return FloatLayout()

if __name__ == "__main__":
    SimpleKivy4().run()
		

This code should look mostly familiar.

The only major changes here are that we're importing the FloatLayout, and we're having SimpleKivy4 (our main class here) returning FloatLayout.

<Button>:
    font_size: 40
	color: 0,1,0,1
	size_hint: 0.3, 0.2 

<FloatLayout>:
    Button:
	    text: "Kivy"
		pos_hint: {"x": 0, 'y':0}
	
	Button:
	    text: "Tutorials"
		pos_hint: {"right": 0.5, 'top':1}
		

Now, we see a few new terms within our .kv file.

First, we see this size_hint variable. Size_hint is a hint at the size of an element, based on portions of the "total" available. 0.3, 0.2 means the element will be 30% of the window wide, and 20% of the window tall.

Next, we spot pos_hint. Pos_hint gives a hint at the position, which is measured relatively between 0 and 1, where 1 is "completely" something and 0 is "not" something.
