Font size Issue while learning HTML


I’m learning HTML and one of the lessons won’t let me continue. It’s telling me my font size is 16px instead of 12px but I have it as it appears to be. I’ve read ever thread on this and I can’t find the problem. Even when I reset that lesson and do nothing I still get the error message "It looks like your second <li>'s font-size is 16px instead of 12px."



Please paste in your HTML& CSS so we can have a look
