jquery 可调整大小的 1px 不匹配错误

Question

我正在尝试使用 jquery 具有绝对位置方形 div 的可调整大小的处理程序

但是当我单击 "north" 和 "west" 按钮（只有这两个方向）并稍微拖动以调整大小时，框本身变小了 1 或 2px

在 north handler 的情况下，例如 (top:100px,height:100px => top:99px,height:99px)

我做错了什么？？

element.resizable({
    minWidth: 1,
    minHeight: 1,
    handles:{
        'n': '.ui-resizable-n',
        'w': '.ui-resizable-w',
        'e': '.ui-resizable-e',
        's': '.ui-resizable-s'
    }
})

这里是a demo link！

当我将 "keeper" 项目拖到 "screen" 并稍微移动北调整大小处理程序时，正方形会出现问题

请将box-sizing: border-box;改为box-sizing: content-box;。
