About HTMLBASICS II Chapter 8 Font size

could you please tell me what the wrong is.

<!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>

it always show up==> Oops, try again. Did you set the first paragraph’s font-size to 10px? It looks like it’s 12px. (If you’re getting a weird decimal font size, check the Hint.)

I’m using Chrome.
font-size is 16.3636360168457px instead of 16px.
You have to enter the ‘Settings’ => ‘Advanced settings’ (in the very bottom)
and to chose 100% in the Page scale (in my browser it was 125%).
