Mix-blend-mode 不影响任何组件

Question

我尝试在网上搜索各种答案并尝试了所有可以解决其他人问题的方法，但我的 CSS 就是不想合作。

Here 你可以找到我重现问题的 JSFiddle：我希望侧边导航也能在黑色部分可见。

HTML
<div class="sidenav">
  <a href="#" class="selected">Section 1</a>
  <a href="#">Section 2</a>
  <a href="#">Section 3</a>
</div>

<div class="content">
  <div>
    <p>Some text<p>
  </div>
  <div class="blk">
    <p>Some text<p>
  </div>
  <div>
    <p>Some text<p>
  </div>
</div>


CSS
.sidenav {
  width: auto;
  position: fixed;
  z-index: 1;
  top: 150px;
  padding: 8px 0;
}

.sidenav a {
  clear: both;
  float: left;
  position: relative;
  left: -20%;
  padding: 10px;
  margin-bottom: 15px;
  transition: 0.3s;

  text-decoration: none;
  text-align: right;
  font-size: 24px;

  border-style: solid;
  border-width: 2px;
  border-color: #0D0D0D;
  border-radius: 0 5px 5px 0;

  color: #0D0D0D;
  mix-blend-mode: difference;
}

.blk {
  background-color: #0d0d0d;
  color: #ffffff;
}

你想要这样的东西吗？

html {
  scroll-behavior: smooth;
  background: #fff;
}

body {
  margin: 0;
  padding: 0;
  width: 100%;
  max-width: 100%;

  background-color: #ffffff;
  color: #0d0d0d;
}

/**********************************************/

.section {
  width: 100vw;
  max-width: 100%;
  background-color: #ffffff;
  text-align: center;

  margin: 0;
  padding: 15vh 0;
  position: relative;
}

.blk {
  background-color: #0d0d0d;
  color: #ffffff;
}

/**********************************************/

.sidenav {
  width: auto;
  position: fixed;
  z-index: 1;
  top: 150px;
  padding: 8px 0;
  mix-blend-mode: difference;
}

.sidenav a {
  clear: both;
  float: left;
  position: relative;
  left: -20%;
  padding: 10px;
  margin-bottom: 15px;
  transition: 0.3s;

  text-decoration: none;
  text-align: right;
  font-size: 24px;

  border-style: solid;
  border-width: 2px;
  border-color: #fff;
  border-radius: 0 5px 5px 0;

  color: #fff;
  background-color: #000;

}

.sidenav a:hover {
  left: -2px;
}

.sidenav a.selected {
  left: -2px;
  color: #000;
  background-color: #fff;
  cursor: default;
}

<!doctype html>
<html>
<head></head>

  <body>

    <div class="sidenav">
      <a href="#" class="selected">&emsp;&emsp;Section 1</a>
      <a href="#">&emsp;&emsp;Another Section</a>
      <a href="#">&emsp;&emsp;Last One</a>
    </div>

    <div class="content" onclick="closeMenu()">
      <div class="section" id="works">
        <p>Some text<p>
      </div>
      <div class="section blk" id="works">
        <p>Some text<p>
      </div>
      <div class="section" id="works">
        <p>Some text<p>
      </div>
      <div class="section blk" id="works">
        <p>Some text<p>
      </div>
      <div class="section" id="works">
        <p>Some text<p>
      </div>
    </div>
  </body>
</html>

您需要将 mix-blend-mode 添加到 sidenav 等父元素，而不是在 a

中更改背景、颜色和边框颜色
