Is this just a site bug or am i doing something obviously wrong?

Why does it keep telling me I need to add a title element in the , when I already do. So confused.

  **Your code so far**
<!DOCTYPE html>
  <title> Registration Form </title>
  <link rel="stylesheet" type="text/css" href="styles.css">
  **Your browser information:**

self closing tags are like this <link />

Ah. Makes sense. It’s quite weird because I’ve been doing it like that for the previous steps since I started and it worked just fine. Odd!
