JavaScript CSS Selectors Quickstart Pseudo-classes and Combinators Combinators Challenge

Help with Task 1 Question (CSS Selectors Quickstart)

I keep getting asked if I am giving the bottom margin of the image 20px. which I am doing and can run in VS Code and see that it works. What am I missing?

Question: Create a selector that targets the <img> element that is a descendant of the <header> element. Apply a bottom margin of 20px.

Answer: header img { margin-bottom: 20px; }

this also works header > img { margin-bottom: 20px; }

/* Complete the challenge by writing CSS below */=-
header img {
  margin-bottom: 20px;
<!DOCTYPE html>
    <title>Combinators Challenge</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
