html - CSS - 更改气泡的“句柄”

Question

我正在修改我在此处找到的一些 CSS/HTML，它显示带有气泡的 iOS 样式聊天消息。我想交换我设法做到的蓝色和绿色气泡的对齐方式，但我唯一不确定的是如何更改出现在左下角和右下角的小“手柄” .

这是它目前的样子：

body {
	background-color: #eee;
	color: #222;
	font: 0.8125em/1.5 'Helvetica Neue', Helvetica, Arial, sans-serif;

我不知道如何交换每个气泡底角的小把手，这样它们就在对面。我希望蓝色的出现在右下角，绿色的出现在左下角。

完整代码在这里：

在下面.bubble:before{..}，.bubble:after {..}您已经使用left了应该为 'bubble--alt:before{..} bubble--alt:after{..}`的属性，right反之亦然。and
