Hey there,
great job so far! 
My ideas:
-
all tests pass, awesome!
-
when you use codepen, you only have to add the code that belongs into the
body; so you can remove this:
<!DOCTYPE html>
<html lang="en">
<head>
...
</head>
<body>
-
after you removed this unnecessary stuff, you can get a code validation by pasting your HTML code into the
body; you will see some small errors and I think you are able to fix them!
-
you can increase the readability of your code by:
- clicking on the small arrow on the right side of the code box and
- clicking
Format HTML/CSS
-
you can increase the overall readability of your page by adding some more spacing, e.g. between the different questions; you can read more about it here
-
when I decrease the width of my browser, the navigation menu is gone, poof; I think, especially on smartphones, when pages get longer, it’s good advice to have a navigation
-
on my wide screen, I’m having a hard time to read the content, because the lines are very long, font size and line height are rather small
Keep us posted and keep up the good work!
