HTML How to Make a Website Styling Web Pages and Navigation Create a Horizontal List of Links

why is nav ul { margin: 0px, 10px;} not a credited answer for task of removing top and bottom margin?

I cannot understand why I am not receiving a correct answer with the above code also the following were not considered correct:

nav ul { margin-top: 0px; margin-bottom: 0px; margin-right: 10px; margin-left: 10px; }

I don't understand why neither of the responses are considered correct.

a {
  text-decoration: none;

#wrapper {
  max-width: 940px;
  margin: 0 auto;

#logo {
  text-align: center;
  margin: 0;

h1, h2 {
  color: #fff;

nav a {
  color: #fff;

nav a:hover {
  color: #32673f;
nav ul {
  margin: 0px, 10px;

h1 {
  font-family: β€˜Changa One’, sans-serif;
  font-size: 1.75em;
  font-weight: normal;

img {
  max-width: 100%;

#gallery {
  margin: 0;
  padding: 0;
  list-style: none;

#gallery li {
  float: left;
  width: 45%;
  margin: 2.5%;
  background-color: #f5f5f5;
  color: #bdc3c7;

Hey Babila,

you're code is theoratically correct but you don't need the comma between the two margin values. So just write:

nav ul {
  margin: 0px 10px;

I hope that was helpful, Patrick
