移动版的:: after（伪元素）模糊内容（动画CSS按钮）

Question

我创建了一个号召性用语按钮，可以在点击时制作一个小动画：

1. 静态并显示ADD TO CART
2. 点击：背景动画（持续时间1秒）和内容='添加到购物车'
3. 1秒后：新的背景颜色并显示添加到购物车转到购物车

按钮模板：

基本上，我使用:: after将背景颜色更改为进度条，然后使用::之前将内容更改为添加到购物车。

一切都很完美但是在移动版本上添加到手机上的文字很模糊。

在桌面和移动设备上打印：

相关代码：

changeBtn() {
  addCartEl.classList.add('global__main-btn--active');
  addCartEl.innerHTML = "Added to cart<span>Go to cart</span>"
}
$('#add-to-cart').on('click', changeBtn());

  0% {
    width: 0%;
    opacity: 1;

  100% {

我有一个类似的问题，并认为它与transform属性有关。一旦我添加了转换，文本就变得模糊了。删除它将解决问题。这似乎是一个webkit或blink引擎错误。
