子像素在浏览器中计算和呈现的方式不同

目的:

我正在处理类似于此的代码,以创建一个输入字段具有嵌入按钮的组件:
http://codepen.io/anon/pen/pgwbWG?editors=110
如您所见,按钮绝对定位top并bottom设置为0,以实现100%高度元素.
另外需要注意的是,文本输入的边框必须保持可见,并且还要包裹按钮.为了达到这个目的,我margin: 1px在按钮上添加了一个,以便(应该是)空间显示周围的文本输入红色边框(通常在输入字段内容无效时).
问题:

就是在Firefox上它(大部分)正确呈现,而在Chrome上(显然在最新的Safari上)它会在按钮底部有1px的间隙.
CSS似乎确定,但它似乎是在渲染,在底部或按钮的上边距是不是真的1px的计算/舍入的问题(可以看到它检查元素).此外,输入的填充似乎也会影响到.
在不同的缩放率下,它会在按钮的顶部或底部添加或删除1px的边距,从而产生1px间隙或覆盖边框.
当我设置按钮边距时0px,底部边距是固定的,但我松开顶部的1px边距,完成覆盖文本输入的红色边框.
例子:

也许我不明白或解释它太冗长,所以这里是错误的一些截图,从不同的缩放在Chrome(注意CSS始终是相同的):
解决方案:

我无法找到跨浏览器的解决方案.如何处理它并获得一致的组件？(请不要使用Javascript)

为什么div比相同内容的多个跨度更长(仅限Chrome)

我有两行10000"." 用等宽字体.第一个是div中的整行,第二个是1000个跨度,每个10".".这是JS小提琴链接:https://jsfiddle.net/fojp5e9z/2/
这里有5000个字符,最后略显引人注目.在10000,你会在顶线获得2个完整的额外长度.

Run Code Online (Sandbox Code Playgroud)
在Chrome中,第一行比另一行长,但在其他浏览器中,行的长度相同.即使添加normalize.css也无济于事.
为什么会发生这种情况,有没有办法在chrome中修复它,所以线条长度相同？
