I keep getting this error with text size



My error message is"Oops, try again. Did you set the first paragraph's font-size to 10px? It looks like it's 16px. (If you're getting a weird decimal font size, check the Hint.)".

<!DOCTYPE html>
		<title>First font size change</title>
		<p style="font size: 10px"> Some text for you to make tiny! </p>
		<p style="font size: 20px"> Some text for you to make normal size! </p>
		<p style="font size: 40px"> Some text for you to make super big!</p>


HI it's missing the - between the font and size
