如果窗口调整大小，我的故障动画左对齐并保持在浏览器窗口的左侧，将正常的WELCOME文本留在中心。动画之前和之后的偏移量为2px，使其看起来很小。我怎样才能将故障集中在一起？＃34; WELCOME＆＃34;超过正常＆＃34;欢迎＆＃34;文本，仍然保持前后动画相互偏移2px？

检查一下。基本上，你的div有100％的宽度。然后当你定位你的伪元素之前和之后，它们将对齐div的左边，而不是＆＃34;欢迎＆＃34;的左边。文本。
我做的是，我在你的＆＃34;故障周围加了一个容器＆＃34; div，使容器display:flex并将display:inline-block添加到毛刺div中，因此它只有文本的宽度。如果它具有文本的宽度，那么如果您定位：after和：before元素，它们将被正确定位，因为.glitch div不再具有100％的宽度。
编辑：这是另一个版本，没有flex而是text-align:center;。
