如何使这个可调整大小的div从边缘调整大小？

我有一个可调整大小且可拖动的框（灰色）。可以通过从角落拉伸盒子来调整大小。

当前只能通过从角落拉伸来调整盒子的大小。我希望也可以从边缘调整大小。从角落拉伸可使其在宽度和高度上均匀缩放。但是，跨一条边缩放只会沿长度缩放。同时，将其缩放到另一个边缘时，将仅沿宽度缩放。我该如何实现？

HTML：

  <div id="outer" style="background-color: yellow; width: 600px; height: 400px; margin-left: 40px; margin-top: 50px;">


        <div class="draggable_div rot">
            <div class="rotatable">
                <div id="inner" class="resizable" style="background-color: #3C3C3C; width: 300px; height: 300px;">
                </div>
            </div>
        </div>

  </div>

  <div id="x_and_y_of_inner">Left: , Right: </div>

JS：

    $('.draggable_div').draggable();


    $( ".draggable_div" ).draggable({
      drag: function( event, ui ) {

        var left_most_cordinates = $("#outer").offset().left;
        var top_most_cordinates = $("#outer").offset().top;

        $("#x_and_y_of_inner").text( "Left: " + left_most_cordinates + " Top: " + top_most_cordinates );

        ui.position.left = Math.min( left_most_cordinates, ui.position.left );
        ui.position.top = Math.min( top_most_cordinates, ui.position.top );
      }
    });

    $('.resizable').resizable({
        aspectRatio: true,
        handles: 'ne, se, sw, nw'
    });



    $(document).on('mouseover', '.rot', function(){
        var tc = $(this);
        tc.rotatable({
            handle:tc.children('.rotate.left, .rotate.right')
        });
        return true;
    });
