Jquery UI - Resizable: alsoResize not accurate?

Ok I'm not using the 'alsoResize' but I've tested and it behaves the same.

Wh开发者_JAVA技巧en you resize the main element, the black border from the bottom element 'marquee' often nudges out of line with the dashed white border from the top element.

$(".layer").resizable({
    //alsoResize: '.marquee',
    resize: function(event, ui) {
        $('.marquee').css({
            width : ui.size.width + "px",
            height : ui.size.height + "px",
            left : ui.position.left + "px",
            top : ui.position.top + "px",
        });
    },
    handles: 'all',
    aspectRatio: true,
});

Using firebug on a local demo, at the stage they go out of line, you can see the inline element styles for left, top and width, height are different.

I wonder if a work around would be to send the position and size stats to function which outputs an exact measurement to both elements? Any simpler options? Thanks

UPDATE:

I've got a workaround which works cleanly.. it is to pass the resizable-calculated dimensions to a function which sets the top layer to these dimensions also.

I'm sure there's a more efficient method to do this, feel free to offer an optimised version..

There seems to be a discrepancy in the size and position reported by the ui parameter to the resize event, and the actual sizes and positions. This is possibly due to a delay between the ui parameter being built and the event being fired.

I experimented using the actual position and size reported at the time of the event running:

        $('.marquee').css({
            'left' : $(this).position().left,
            'top' : $(this).position().top,
            'width' : $(this).width(),
            'height' : $(this).height()
        });

This seems to match much more precicely the actual dimensions. http://jsfiddle.net/VDfpY/1/

How about this? Let the CSS handle the sizes and not the JS http://jsfiddle.net/HerrSerker/uGr3w/5/
