I am totally a beginner, I have no idea what is happening but nothing appears in my preview page.

<!-- file: index.html -->
<!DOCTYPE html>
  <html>
    <head>
      <title>Survey Form<title/>
    <head/>
    <body>
      <header>
       <h1>Code Learner Survey Form<h1/>
      <header/> 
    <body/>
  <html/>

/* file: styles.css */
