混合混合模式按钮悬停事件问题

Mix Blend Mode button hover event issue

我正在尝试让 mix-blend-mode 正常工作,以便出现背景幻灯片。我整理了 a jsfiddle of it sort of working.

问题是,需要它看起来 more like this

但我不想消除它的倾斜或从右侧滑入。我已经尝试使用与该示例相同的混合模式,但无论我做什么,它都不会在悬停时保持红色幻灯片颜色,在红色下保持白色文本。我只想使用伪元素,并将 html 保持在最低限度。我认为使用伪元素是可能的,但是混合模式与我不合作并且不确定如何让它看起来更像第二个 fiddle。我的html如下:

<a href="#" class="btn">View Project</a>

CSS 是:

a {
  position: relative;
  text-decoration: none;
  display: inline-block;
  padding: 15px 30px;
  border: 1px solid #f16251;
  background: black;
  color: #f16251;
  font-size: 30px;
  font-family: arial;
  mix-blend-mode: normal;
  overflow:hidden;
  z-index: 1;
}
a:before {
  content: '';
  position: absolute;
  top: 0; bottom: 0; right: 0;
  width: 100%; height: 100%;
  background: red;
  mix-blend-mode: multiply;
  transform-origin:0 0 ;
  transform:translateX(100%) skewX(30deg);
  transition: transform .25s;
  z-index: 3;
}
a:hover:before {
  transform: translateX(45%) skewX(30deg);
}
a:hover:after {
  position: absolute;
  top: 0; bottom: 0; left: 0; right: 0;
  width: 100%;
  height: 100%;
  background: white;

}
a:after {
    content: '';
    position: absolute;
    top: 0; bottom: 0; right: 0;
    width: 100%; height: 100%;
    background: white;
    mix-blend-mode: difference;
    z-index: 2;
}

如何让背景文本仅在红色滑过文本时显示为白色?我的 mix-blend-mode 代码一定是错误的,但看起来可以在这里做。

嗯,这很有趣 :)
