我需要将内容可编辑div的大小设置为与其中的文本相同

。请看这个js小提琴https://jsfiddle.net/felixtm/jaboLc3u/7/

      $(".new-div").css("width",'auto');
                                     } ,
                                     stop: function() { 
                                    $(".new-div").css("width",'auto');
                                     }
                                  });
         $(document).on("click",".closeButton",function(){

                                    $(this).closest('div').remove();
                                 });

         $(".new-div").on("click", function(){

                    var uscontent= $(".new-div").text();

                    if(uscontent.trim()==="message"){
                    $(".new-div").text('');

                      } });  

       $("#font-size").on("change",function(){
                     var v=$(this).val();
                      $('.new-div').css('font-size', v + 'px');
                     });
$('.resizeButton').draggable({
containment: '#bord',
drag: function() {
    $('.new-div').height($('.resizeButton').position().top + 17);
    $('.new-div').width($('.resizeButton').position().left + 17);
  $('.new-div').width($('.resizeButton').position().left + 17);

    $('.new-div').css({ 'font-size': ($('.new-div').height() / 2.3)});


}
})                     

.new-div { 
    z-index: 1; position: absolute; width: auto; word-break: break-all; text-align: center; left: 0px; right: 0px; top: 15px; border:2px solid black;}
.parent-div {  
    max-width: 236px; width: 236px; position: relative; overflow: hidden; }

.closeButton
{
    display:block;
    position:absolute;
    top:-10px;
    left:-10px;
    width:27px;
    height:27px;
    background:url('http://cdn-sg1.pgimgs.com/images/pg/close-button.png') no-repeat center center;
}
.resizeButton

        </div>

     </div>
 </div>

这里首先加载内容可编辑div和文本内容的大小是正确的。但是当我尝试调整div的大小时,文本和div的边界之间会出现间隙。

有些时候这个问题也来了http://www.awesomescreenshot.com/image/1753603/d27436262d454bee88bf53ebfab2049a

我尝试了display:inline-block;,但它无效。

如何解决这个问题?

你的意思是填充可调整大小的div? https://jsfiddle.net/bimbonkens/2mpjkxad/

padding: 0;

这将解决您的字体大小问题,这比看起来更棘手。
