	// and also partly from stackoverflow.com/questions/57727107/
	// then I remembered about ternary operators and I optimized it
	// This allows the license to be properly formatted
	// on any screen size by getting the resolution then
	// setting fontSize to a value based on that where the whole
	// line can be viewed without scrolling horizontally
	// or with wrapped text, ruining the required formatting I have.
	// As of 2022-06-08, I have not tested this on a phone.
