A nice small demo you can easily upgrade and modify:

$('#tags input').on('focusout',function(){    
  var txt = $.trim( this.value );
  if(txt) {
    $(this).before('<span class="tag">'+txt+'</span>');
  }
  this.value = "";  
});


$('#tags').on('click','.tag',function(){
  if( confirm("Really delete this tag?") ) $(this).remove();
});

#tags{
  float:left;
  border:1px solid #ccc;
  padding:5px;
  font-family:Arial;
}
#tags span.tag{
  display:block;
  float:left;
  color:#fff;
  background:#689;
  padding:5px;
  padding-right:25px;
  margin:4px;
}
#tags span.tag:after{
  position:absolute;
  content:"x";
  border:1px solid;
  padding:0 4px;
  margin:3px 0 10px 5px;
  cursor:pointer;
  font-size:10px;
}
#tags input{
  background:#eee;
  border:0;
  margin:4px;
  padding:7px;
  width:auto;
}

<div id="tags">
  <input type="text" value="" placeholder="Add a tag" />
</div>
