How to center body on a page?

I'm trying to center the body element on my HTML page.

Basically, in the CSS I set the body element to be display: inline-block; so that it is only as wide as its contents. That works fine. However, margin: 0px auto; doesn't center it on the page.

Does anyone know how to fix this? I want the big blue square to be centered on the page, not floating to the left like it is now.

Here's my CSS:

body {
    display: inline-block;
    margin: 0px auto;
    text-align: center;
}

Also apply text-align: center; on the html element like so:

html {
  text-align: center;
}

A better approach though is to have an inner container div, which will be centralized, and not the body.

    body
    {
        width:80%;
        margin-left:auto;
        margin-right:auto;
    }

This will work on most browsers, including IE.

You have to specify the width to the body for it to center on the page.

Or put all the content in the div and center it.

<body>
    <div>
    jhfgdfjh
    </div>
</body>

div {
    margin: 0px auto;
    width:400px;
}

For those that do know the width, you could do something like

div {
     max-width: ???px; //px,%
     margin-left:auto;
     margin-right:auto;
}

I also agree about not setting text-align:center on the body because it can mess up the rest of your code and you might have to individually set text-align:left on a lot of things either then or in the future.
