css - Centering text block within Bootstrap's carousel -

i'm trying center block of text (not each line of text) within bootstrap carousel item. if use div within carousel item , specify classes "container" , "center-block", block of text shifts right bit, isn't centered horizontally. hoping avoid using fixed margins center text. here's example of i've tried:

<div id="mycarousel" class="carousel slide">     <div class="carousel-inner">         <div class="item active">             <div class="container center-block">                  <h3>list</h3>                 <ol>                     <li>item 1</li>                     <li>item 2</li>                     <li>item 3</li>                 </ol>                 <p> test of longer string</p>             </div>         </div>     </div> </div>
