css - How to automatically center a div element that is inside another div element -

-

let's suppose following use case: working example plese @ link

the html code:

<div class="container">     <div class="centerelem">          width of div variable     </div> </div>

the css style:

.container {     width: 500px; /*this can change */ } .container .centerelem{     margin-right: auto /*unfortunately, works if set width*/     margin-left: auto /*unfortunately, works if set width*/ }

right works this:

        ||the width of div variable|                            |

and make working this, without knowing width of inner div element:

        |                |the width of div variable|            |

it's bit annoying because code in question doesn't match code in jsfiddle,.

use display: inline-block on .subcon, combined text-align: center on .container, have.

like so: http://jsfiddle.net/thirtydot/euytq/66/

or code in question: http://jsfiddle.net/thirtydot/euytq/67/
