css - 更改与背景重叠的部分文本的颜色

问题描述

我想将9 cards与移动背景元素重叠的文本部分的文本颜色更改为白色。我如何实现这一目标？

我看了看，mix-blend-mode: screen;但似乎不适用于这种情况。在这里，我为代码片段导出了编译后的 css/html：

.wrapper {
  padding: 30px 0;
}

.chapter {
  margin-bottom: 20px;
  min-height: 200px;
  border-radius: 6px;
  background-color: #f6f8f9;
  padding: 50px 60px;
  overflow: hidden;
  position: relative;
  display: flex;
  flex-direction: column;
  justify-content: space-between;
}

.chapter__title {
  z-index: 1;
  position: relative;
  font-size: 24px;
  font-weight: 500;
  line-height: 1.25;
  color: #444;
  text-decoration: none;
  transition: color 0.4s ease-in;
}

.chapter__link,
.chapter a {
  z-index: 1;
  position: relative;
  font-size: 20px;
  font-weight: 300;
  line-height: 1.5;
  transition: color 0.4s ease-in;
}

.chapter__link i,
.chapter a i {
  font-size: 60%;
  margin-left: 5px;
  position: relative;
  bottom: -2px;
}

.chapter__label {
  position: absolute;
  right: 15px;
  top: 10px;
  font-size: 14px;
  text-transform: uppercase;
  z-index: 1;
}

.chapter__label--gray {
  text-transform: none;
  color: #aaa;
}

.chapter:after {
  content: "";
  z-index: 0;
  position: absolute;
  right: 30px;
  bottom: 0;
  width: 400px;
  height: 400px;
  background-color: #0a95ff;
  transform: translateX(-100%) translateY(-100%);
  border-radius: 50%;
  box-shadow: 0 0 0 0 #0a95ff;
  transition: transform 0.4s ease-out, box-shadow 0.4s ease-in, background-color 0.2s ease-out;
}

.chapter:hover {
  text-decoration: none;
  cursor: pointer;
}

.chapter:hover .chapter__title {
  color: white;
}

.chapter:hover .chapter__link,
.chapter:hover a {
  color: white;
}

.chapter:hover .chapter__link span:after,
.chapter:hover a span:after {
  width: 100%;
  background-color: white;
  transition: background-color 0.4s ease-in, width 0.2s ease-in;
  transition-delay: 0, 0.4s;
}

.chapter:hover:after {
  right: 30px;
  bottom: 0;
  transform: none;
}

.chapter:active:after {
  box-shadow: 0 0 0 300px #0a95ff;
}
