Placing nav bar inside the header

Hi! I'm struggling to place my navigation bar inside my header. I want my navigation bar to float right and my header to stay on the left. It would be awesome if anyone can help me understand why my nav bar keeps getting pushed down instead of going in my header. Thank you so much in advance!

<!DOCTYPE html>



 <meta charset="utf-8">
 <title>The MMA Bros</title>
 <link href="style.css" rel="stylesheet" type="text/css">



  <div class="wrapper">
   <div class="header">
    <h1>The MMA Bros</h1>

  <div class="nav">



/* GLOBAL */

* {
    margin: 0;
    padding: 0;

/* BODY*/

body {
    font-family: sans-serif, arial, helvetica;
    background: #000;

/* HEADER */

.wrapper {
    width: 100%;

.header {
    background-color: #a8baf1;
    color: #fff;
    height: 100px;
    border-bottom: 2px solid #fff;

.header h1 {
    padding-top: 20px;
    padding-left: 25px;
    font-size: 60px;


.nav {
    color: #fff;
    float: right;

.nav li {
    display: inline;
    padding-right: 25px;
    padding-left: 25px;
    font-size: 25px;

You may be getting confused since you have a class named "header" and also a header element. The CSS colors the class light blue, but it's just a container around the h1. It does not include the nav.

And since h1's are block elements the nav section is pushed down below it. And since the header element is constrained to a height of 100 pixels, which is about the size of the h1, the nav section is further out.

Then add the fact that the nav is floated, and that causes the header element along with the "wrapper" to both collapse down to fit tightly around the h1.

So there you have it. Adding this should make things a bit more obvious:

header { overflow: scroll; }

The built-in developer tools in the browser would also help reveal the issue (that's what I used).
