Lesson 9, Error message says size is 16px, not 10 px, but it is 10px. Can't move on. Please help

<!DOCTYPE html>
        <title>Changing the colors!</title>
        <h2 style="color: green; font-size 16 px">Big Heading</h2>
            <p style= "color: violet">A giant bear and a little duck were friends.</p>
            <p style= "color: red; font-size 10 px">But the bear got hungry and ate the duck.</p>

There are two problems, after a problem (font-size) there should be a colon, it is missing.

And 16px (same for 10) is one argument, can’t be a space between 16 and px

Thanks! That did it.
