I'm trying to create a horizontal nav bar using CSS and display: inline; but I'm having no joy with it. Using `<ul><li>`, I am getting a vertical list rather than a horizontal one. I've Googled the web and poured over SO but can't find a fix. 

```css
#menu ul {
  height: 15px;
  padding: 8px 0px;
  margin: 0px;
}
#menu li {
  text-decoration: none;
  display: inline-block;
  padding: 20px;
  float: left;
}
.logo {
  font-family: 'Mr De Haviland', cursive;
  font-size: 32px;
}
.logo a {
  color: black;
  text-decoration: none;
}
#nav a {
  color: black;
  text-decoration: none;
}
#nav {
  max-width: 600px;
  width: auto;
  height: 35px;
  font-size: 16px;
  font-family: Helvetica, Geneva, sans-serif;
  text-align: center;
  text-shadow: 3px 2px 3px #666666;
  background-color: #999999;
  border-radius: 8px;
  list-style-type: none;
}
```

```html
<!DOCTYPE html>
<html lang="en-gb">

<head>
  <meta charset="utf-8">
  <link href='https://fonts.googleapis.com/css?family=Mr+De+Haviland' rel='stylesheet' type='text/css'>
  <link rel="stylesheet" type="text/css" href="index.css">
  <title>Anthony Jones</title>
</head>

<body>
  <div id="main">
    <div class="logo">
      <p align="center">
        <a class="logo" href="index.html">Anthony Jones</a>
      </p>
    </div>

    <div id="nav">
      <ul style="list-style-type: none;">
        <a href="about.html">
          <li>About</li>
        </a>
        <a href="cv.html">
          <li>Curriculum Vitae</li>
        </a>
        <a href="services.html">
          <li>Services</li>
        </a>
        <a href="random.html">
          <li>Random</li>
        </a>
        <a href="contact.html">
          <li>Contact Me</li>
        </a>
      </ul>
    </div>

  </div>
</body>
```

The `ul style="list-style-type: none;"` in the `<style>` tag is there because I couldn't remove the bullet points within the **index.css** file, this was the only solution I could find.

I've tried many variations on the code, rearranged it, deleted and started over and still no joy. Any ideas?
