材料设计精简版中的左对齐，中心与右对齐

Question

我正在使用材料设计精简版，并尝试将内容对齐到左/右/中。但无法执行它。这里是

<div class="mdl-card__actions mdl-card--border"> 

        <button id="share-menu" class="mdl-button mdl-button--icon mdl-js-button mdl-js-ripple-effect pull-left"> 
         <i class="material-icons">share</i> 
        </button> 
        <ul class="mdl-menu mdl-menu--bottom-left mdl-js-menu mdl-js-ripple-effect" 
         for="share-menu"> 
         <li class="mdl-menu__item">Some Action</li> 
         <li class="mdl-menu__item mdl-menu__item--full-bleed-divider">Another Action</li> 
         <li disabled class="mdl-menu__item">Disabled Action</li> 
         <li class="mdl-menu__item">Yet Another Action</li> 
        </ul> 
        <span class="mdl-chip mdl-chip--contact center-block"> 
         <span class="mdl-chip__contact mdl-color--teal mdl-color-text--white">12</span> 
         <button class="mdl-button mdl-button--icon mdl-button--colored"><i class="material-icons">thumb_up</i></button> 
        </span> 
        <button class="mdl-button mdl-button--icon mdl-button--colored pull-right"><i class="material-icons">add_shopping_cart</i></button> 
       </div> 

我想中心的文字，MDL-排版代码 - 文本中心级，但设计是不完美这里是屏幕截图

拉左而右拉正在工作，但中心不工作。我怎样才能做到这一点？

Answer 1

它将努力尝试：

.mdl-card__actions {text-align:center;} /* will make the text in center */ 
.mdl-chip--contact {display: inline-block; float: none;} /* because it is inline-block it will be affected by text-align property in parent element */
