CSS CSS Layout Basics Getting Started with CSS Layout Centering Page Content and Creating a Full-width Header

header not showing in the same line, margin 0 doesn't work

I've been trying to make a header with a navigation bar but all the elements are not expanding throughout the screen, and the margin property I typed isn't working for some reason.

Could anyone review my css file and see what i've missed? I've also attached my html file.

/* base element styles */

* {
  box-sizing: border-box;

body {
  font-family: 'Cormorant Garamond', serif;
  line-height: 1.8;
  color: #000;
  margin: 0;

p {
  font-size: .5em;
  margin-bottom: 2em;

a {
  text-decoration: none;

img {
  max-width: 100%;

/*base layout styles*/


.name {
  font-size: 1em;
  margin: 0;
  color: #0d0d0d;

.main-nav {
  margin-top: 5px;

.name a,
.main-nav a {
  text-align: center;
  display: block;
  margin-top: .5em;
  padding: 10px 15px;
  color: #000;
  width: 100%;

.main-nav a {
  font-size: .95em;
  color: #333;

.main-nav a:hover {
  color: #666;

/* ---- Layout Containers ---- */

.main-header {
  position: fixed;
  width: 100%;
  padding-top: .5em;
  padding-bottom: .1em;
  z-index: 100;
  box-shadow: 0 1px 4px rgba(0,0,0,.1);

/* =================================

==================================== */
@media (min-width: 769px) {

  .name {
    float: left;

  .main-nav {
    float: right;

  .main-nav li {
    display: inline-block;
    margin-left: 20px;

  /* ---- Float clearfix ---- */

  .clearfix::after {
    content: " ";
    display: table;
    clear: both;

You have some syntax issues (mismatched tags) on this line:

         <h1 class="name"><a href="#">Portfolio</li>

There's no end tag for either the anchor ("a") element or the heading ("h1") element, and there's a stray end tag for a list item ("li") that was never started. You probably want this instead:

         <h1 class="name"><a href="#">Portfolio</a></h1>

ahh thank you so much steven! it works now
