Top margin 0 where I have to place this?

I added the margin left and right like requested, when I check I have the message to set the top margin 0, I tried to write this everywhere, but the answer is the same.

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;

h1 {
  font-family: 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;

Hi Patrizia,

Can you try adding the following to the bottom of your CSS file please?

nav ul {margin: 0 10px;}

This will target all unordered lists inside a nav element, remove any top / bottom margin and give a left / right margin of 10px.

Hope that helps.


Thank you Rich! It worked

No problem :)

First, when you include your code, you should include the part that you wrote so we can see what might be wrong. I'm not seeing that included above.

This code wants you to use the margin short hand, so this is the code that you should include:

nav ul {
  margin: 0 10px;

When using the margin shorthand when you only declare two values the first affects the top and bottom margins, and the second affects the right and left margins.
