HTML Introduction to HTML and CSS Getting Familiar with HTML and CSS Test: Changing the Look of a Web Page

Broken test won't let me pass with a right answer

It told me to change to paragraph tag to an h1 tag. I did it now and checked the work but it's not moving forward.

index.html
<!doctype html>
<html>
  <head>
    <link href="styles.css" rel="stylesheet">
  </head>
  <body>

    <h1>Welcome to My Web Page!</h1>

  </body>
</html>
styles.css
h1 {
  color: blue;
}

It worked thanks
