What could be causing the odd gap between the menu and the top of the webpage?

I created a basic navigation bar using HTML, but there seems to be a slight gap between the top of the nav and the top of the page.

Here is the HTML code:

<div id="nav">
    <div id="menu">
      <ul>
        <li><a href="#">Home</a></li><li>
        <a href="#">About</a></li><li>
        <a href="#">Dowenload</a></li><li>
        <a href="#">Contact</a></li>
      </ul>
    </div>
</div>

And here is the CSS code:

body{
  margin:0px;
  background-color:green;
}
#menu ul{

}
#menu ul li{
  display: inline-block;
  list-style-type: none;
  font-size:20px;
  padding:15px;
}
#menu ul li a{
 text-decoration: none;
 color:#ccc;
}

You can view a demo here.

Does anyone have any suggestions on how to resolve this issue?

Answer №1

Ensure that #menu ul has the property margin: 0;

Check out the demonstration on JSFiddle - DEMO

body{
    margin:0px;
    background-color:green;
}
#menu{
width:100%;
height:53px;
background: -webkit-linear-gradient(#222, black); /* For Safari 5.1 to 6.0 */
  background: -o-linear-gradient(#222, black); /* For Opera 11.1 to 12.0 */
  background: -moz-linear-gradient(#222, black); /* For Firefox 3.6 to 15 */
  background: linear-gradient(#222, black); /* Standard syntax */
}
#menu ul{
margin: 0;
}
#menu ul li{
display: inline-block;
list-style-type: none;
font-size:20px;
padding:15px;
}
#menu ul li a{
text-decoration: none;
color:#ccc;
}
#menu ul li:hover{
background: -webkit-linear-gradient(#222, #1A1A1A); /* For Safari 5.1 to 6.0 */
  background: -o-linear-gradient(#222, #1A1A1A); /* For Opera 11.1 to 12.0 */
  background: -moz-linear-gradient(#222, #1A1A1A); /* For Firefox 3.6 to 15 */
  background: linear-gradient(#222, #1A1A1A); /* Standard syntax */
}

<div id="menu">
<ul>
<li><a href="#">Home</a></li><li>
<a href="#">About</a></li><li>
<a href="#">Download</a></li><li>
<a href="#">Contact</a></li>
</ul>
</div>

<div id="content">

<div id="footer">

</body>

Answer №2

#navigation ul{
    padding-top: 0px;
}

Check out this example: http://jsfiddle.net/gwytx6g4/2/

If you want to remove the margin below the navigation bar, using padding: 0px; will do the trick too.

To view the margins, simply right-click on the navbar in Google Chrome, select "inspect element", and ensure that #navigation ul is highlighted in the code displayed on the left side.

Answer №3

Utilize a reset css file or implement the following code:

*{
   margin:0;
   padding:0;
}

This is necessary because by default, elements have 8px of margin space which can vary between browsers. Resetting them with margin: 0 and padding: 0 ensures consistency.
