Problem 10: Font Family

my code isn’t working right and I don’t know why

<!DOCTYPE html>
		<title>Loving the font changes</title>
		<h1 style="font-family: Arial">Big title</h1>
		 	<li style="font-size 16px; font-family: Arial">This item is big Arial.</li>
		 <li style="font-size 12px; font-family: Verdana">This item is medium Verdan.</li>
		<li style="font-size 10px; font-family: Impact"> This item is small Impact.</li>

In your li element’s style attribute, you are missing some colons. Particularly after font-size. It should be like font-size: 12px;.
