标题: html - Place input box at the center of div

I have a div, and I want the input box to be place at it's center. How can I do this?

The catch is that input elements are inline. We have to make it block (display:block) before positioning it to center : margin : 0 auto. Please see the code below :

<html>
<head>
    <style>
        div.wrapper {
            width: 300px;
            height:300px;
            border:1px solid black;
        }

        input[type="text"] {
             display: block;
             margin : 0 auto;
        }

    </style>
</head>
<body>

    <div class='wrapper'>
        <input type='text' name='ok' value='ok'>
    </div>    


</body>
</html>

But if you have a div which is positioned = absolute then we need to do the things little bit differently.Now see this!

  <html>
     <head>
    <style>
        div.wrapper {
            position:  absolute;
            top : 200px;
            left: 300px;
            width: 300px;
            height:300px;
            border:1px solid black;
        }

        input[type="text"] {
             position: relative;
             display: block;
             margin : 0 auto;
        }

    </style>
</head>
<body>

    <div class='wrapper'>
        <input type='text' name='ok' value='ok'>
    </div>  

</body>
</html>

Hoping this can be helpful.Thank you.
