div 两侧的径向梯度（但为负）

Question

所以，我想实现这种渐变效果，但我不知道该怎么做。

这是codepen link https://codepen.io/christmastrex/pen/vYmyZWR

这是我的代码

<div class="bg--red-gradient">
  <h2>Lorem ipsum lorem ipsum <br>lorem ipsum lorem ipsum.</h2>
</div>

.bg--red-gradient {
  margin: 0 auto;  
  text-align: center;
  color: #fff;
  max-width: 600px;
  padding: 10px 50px;
  background: linear-gradient(
    90deg,
    rgba(0, 0, 0, 0) 0%,
    rgba(195, 50, 80, 1) 25%,
    rgba(195, 50, 80, 1) 50%,
    rgba(195, 50, 80, 1) 75%,
    rgba(0, 0, 0, 0) 100%
  );
}

我的代码的问题是渐变在末端不是径向的。有帮助吗？

这可以通过两个径向渐变来实现，每个渐变都淡出以避免重叠：

.bg--red-gradient {
  margin: 0 auto;  
  text-align: center;
  color: #fff;
  max-width: 600px;
  padding: 10px 50px;
  background: 
    radial-gradient(
      circle at 0%, /* Position on the left edge */
      rgba(0,0,0,0) 0%, 
      rgba(0,0,0,0) 10%, /* This 10% value can be adjusted to change the radius of the gradient */
      rgba(195, 50, 80, 1) 50%,
      rgba(0,0,0,0) 100%
    ), 
    radial-gradient(
      circle at 100%, /* Position on the right edge */
      rgba(0,0,0,0) 0%,
      rgba(0,0,0,0) 10%,
      rgba(195, 50, 80, 1) 50%,
      rgba(0,0,0,0) 100%
    );
}

<div class="bg--red-gradient">
  <h2>Lorem ipsum lorem ipsum <br>lorem ipsum lorem ipsum.</h2>
</div>
