Put the span on top of the div

I've built some social buttons with counters. And I want the counter data to be displayed on top of my buttons. Somehow they are always inside buttons.

• Can the number of shares be placed on top of a button like?

• Every social button contains text inside, although I put float: left
  
  and text-align: left
  
  , the text that still appears in the center, why?

My HTML:

<a class="post-share facebook entShare" target="entsharewindow" href="#">
<div class="social-buttons-text">Facebook Like</div><span>0</span>
</a> 
<a class="post-share facebook entShare" target="entsharewindow" href="#">
<div class="social-buttons-text">Facebook Share</div><span>0</span>
</a> 
<a class="post-share twitter entShare" target="entsharewindow" href="#">
<div class="social-buttons-text">Twitter</div><span>0</span>
</a> 

      

        
        
        
      

    

My CSS:

 a.post-share {
    display: block;
    width: 74px;
    height: 34px;
    float: left;
    margin: 10px 0px 0px 0px;
    background: #3e599a url(sidebar-share.png) no-repeat 0 0;
    text-decoration:none;
    width: 110px;
    text-indent: 50px;
    font: 15px/46px "Helvetica Neue", Arial, Helvetica, Geneva, sans-serif;
    color: #FFFFFF;
}
a.post-share:hover {
    opacity: 0.8;
    text-decoration: none;
    cursor: pointer;
}

a.post-share span {
    width: 22px;
    height: 18px;
    padding: 3px;
    display: block;
    float:right;
    background-color:#080563;

    vertical-align: middle;

    text-indent: 0;
}

a.post-share.facebook {

background-image: url('/images/social-icons/facebook-32.png');
margin-right: 10px;
}

a.post-share.facebook {
