How to center an unordered list?

问题

I need to center an unordered list of unknown width, while still keeping the list-items left aligned.

Achieve the same result as this:

HTML

<div>
    <ul>
        <li></li>
        <li></li>
        <li></li>
    </ul>
</div>

CSS

div { text-align: center; }
ul { display: inline-block; text-align: left; }

Except my <ul> doesn't have a parent div. ul { margin: 0 auto; } doesn't work because I don't have a fixed width. ul { text-align: center; } doesn't work because the list-items won't be left aligned anymore. So how can I center this <ul> while keeping the <li>s left aligned (without having a parent div wrapper)?

<ul>
    <li></li>
    <li></li>
    <li></li>
</ul>

EDIT: Perhaps my wording wasn't the best... The first block of code already works... what i need is to do it without the <div> wrapper, if that's possible of course. Float tricks? Pseudo element tricks? There must be a way.

ul { display:table; margin:0 auto;}

<html>
<body>    
<ul>
        <li>56456456</li>
        <li>4564564564564649999999999999999999999999999996</li>
        <li>45645</li>
    </ul>
    </body>
</html>

If it is possible for you to use your own list bullets

Try this:

<html>
    <head>
        <style type="text/css">

            ul {
                margin:0;
                padding:0;
                text-align: center;
                list-style:none;                
            }
            ul  li {
                padding: 2px 5px;               
            }

            ul li:before {
                content:url(http://www.un.org/en/oaj/unjs/efiling/added/images/bullet-list-icon-blue.jpg);;
            }
        </style>
    </head>
    <body>

            <ul>
                <li>1</li>
                <li>2</li>
                <li>3</li>
            </ul>

    </body>
</html>

To center align an unordered list, you need to use the CSS text align property. In addition to this, you also need to put the unordered list inside the div element.

Now, add the style to the div class and use the text-align property with center as its value.

See the below example.

<style>
.myDivElement{
    text-align:center;
}
.myDivElement ul li{
   display:inline;

 }
</style>
<div class="myDivElement">
<ul>
    <li>Home</li>
    <li>About</li>
    <li>Gallery</li>
    <li>Contact</li>
</ul>
</div>

From your post i understand that you cannot set width to your li

so wt about this ?

<ul>
    <li>Hello</li>
    <li>Hezkdhkfskdhfkllo</li>
    <li>Hello</li>
</ul>

css

ul{
border:2px solid red;
display:inline-block;
}
li{
  display:inline;
  padding:0 30%; /* try adjusting the side % to give a feel of center aligned.*/
}
