Why would "margin: 0;" tell me not all sides have zero margin?

I'm confused as to why setting a margin of 0 wouldn't automatically assign it to all sides.

#gallery ul {
  margin: 0;
  padding: 0;
 list-style-type: none;
}
css/main.css 
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 ul {
  margin: 0;
  padding: 0;
  list-style-type: none;
}

Tyler,

The margin property is shorthand for margin-top, margin-right, margin-bottom and margin-left. It's typically easier to use this to avoid having to list out each one separately.

margin: 0; // is equivalent to 
margin: 0, 0, 0, 0; // margin: top, right, bottom, left — or
margin-top: 0;
margin-right: 0;
margin-bottom: 0;
margin-left: 0;

Check out the Mozilla Developer Network (MDN) for more information — great resource.
