How to center horizontally div inside parent div

Question

How do I center a div horizontally inside its parent div with CSS?

<div id='parent' style='width: 100%;'>
 <div id='child' style='width: 50px; height: 100px;'>Text</div>
</div>

Answer 1

<div id='child' style='width: 50px; height: 100px; margin:0 auto;'>Text</div>

Answer 2

I am assuming the parent div has no width or a wide width, and the child div has a smaller width. The following will set the margin for the top and bottom to zero, and the sides to automatically fit. This centers the div.

div#child {
    margin: 0 auto;
}

Answer 3

<div id='parent' style='width: 100%;text-align:center;'>
 <div id='child' style='width:50px; height:100px;margin:0px auto;'>Text</div>
</div>

Answer 4

You can use the "auto" value for the left and right margins to let the browser distribute the available space equally at both sides of the inner div:

<div id='parent' style='width: 100%;'>
   <div id='child' style='width: 50px; height: 100px; margin-left: auto; margin-right: auto'>Text</div>
</div>
