Centering with margin - html

Question

I would to make my navbar on center. Tried this:
#menu {
position: relative;
height: 44px;
width: auto;
padding-left:165px;
}
But, this code does not works on large screen or zoom out. And I've tried
margin-left:auto;
margin-right:auto;
Here is my full navbar codes
#menu {
position: relative;
height: 44px;
width: auto;
margin: 0px auto;
}
#menu ul {
list-style: none;
padding: 0;
margin: 0;
line-height: 1;
}
#menu > ul {
position: relative;
display: block;
background: -moz-linear-gradient(#4F93EF, #1162CB);
background: -o-linear-gradient(#4F93EF, #1162CB);
background: -webkit-linear-gradient(#4F93EF, #1162CB);
/*border-radius: 15px 15px 0px 0px;
-moz-border-radius: 15px 15px 0px 0px;
-webkit-border: 15px 15px 0px 0px;*/

I've tried margin-left auto, margin-right auto and margin 0px auto
Still does not work, any solution guys?

Answer 1

Need to fix the width of the parent tag and set the style="margin:0px auto;"

Answer 2

Your use of margin-left and margin-right is incorrect, it should be:
margin-left:auto;
margin-right:auto;

Answer 3

Try to use left and right with auto
#menu {
position: relative;
height: 44px;
width: auto;
margin-left:auto;
margin-right:auto;
float:none !important;
}

Answer 4

try the following:
#menu {
position: relative;
height: 44px;
width: 500px;
right: 0;
left: 0;
margin-right: auto;
margin-left: auto;
background-color: red;
color: white;
display: block;
}
PS: try the position as absolute or fixed also instead of relative.
