如何防止级联过滤器。或撤消级联过滤器

Question

我找不到解决我问题的方法。从Codepen中可以看到，我想对父元素应用滤镜，以使图像模糊。问题是文本子元素也变得模糊，当我尝试应用filter:none时，它不会更改文本中的任何内容。为什么会这样呢？我该如何预防呢？谢谢。

.albums__item {
  position: relative;
  width: 500px;
  height: 500px;
  transition: all .4s;
}

.albums__img {
  object-fit: cover;
  width: 100%;
  height: 100%;
}

.albums__item:hover {
  filter: blur(2.5px);
}

.albums__item:hover>.albums__caption {
  filter: none;
}

.albums__caption {
  position: absolute;
  top: 45%;
  left: 50%;
  transform: translate(-50%, -50%);
  width: 85%;
  text-align: center;
  color: #fff;
  font-size: 3rem;
  font-weight: 300;
  letter-spacing: 2.5px;
  display: flex;
  flex-direction: column;
}

.albums__caption--year {
  margin-top: 6rem;
  font-size: 3.5rem;
}

.albums__caption {
  visibility: hidden;
  opacity: 0;
  transition: all .6s;
}

.albums__item:hover>.albums__caption {
  visibility: visible;
  opacity: 1;
}

<figure class="albums__item albums__item--1">
  <img class="albums__img" src="https://pbs.twimg.com/media/DTVfQ4DX4AEYtmO.jpg" alt="Album image Koyu Antoloji">
  <figcaption class="albums__caption">
    <div class="albums__caption--name mb-md">Koyu Antoloji</div>
    <div class="albums__caption--year">2017</div>
  </figcaption>
</figure>

将filter放在图片上...而不是包装纸上

.albums__item:hover img {
  filter: blur(2.5px);
}

.albums__item {
  position: relative;
  width: 500px;
  height: 500px;
  transition: all .4s;
}

.albums__img {
  object-fit: cover;
  width: 100%;
  height: 100%;
}

.albums__item:hover img {
  filter: blur(2.5px);
}

.albums__item:hover>.albums__caption {
  filter: none;
}

.albums__caption {
  position: absolute;
  top: 45%;
  left: 50%;
  transform: translate(-50%, -50%);
  width: 85%;
  text-align: center;
  color: #fff;
  font-size: 3rem;
  font-weight: 300;
  letter-spacing: 2.5px;
  display: flex;
  flex-direction: column;
}

.albums__caption--year {
  margin-top: 6rem;
  font-size: 3.5rem;
}

.albums__caption {
  visibility: hidden;
  opacity: 0;
  transition: all .6s;
}

.albums__item:hover>.albums__caption {
  visibility: visible;
  opacity: 1;
}

<figure class="albums__item albums__item--1">
  <img class="albums__img" src="https://pbs.twimg.com/media/DTVfQ4DX4AEYtmO.jpg" alt="Album image Koyu Antoloji">
  <figcaption class="albums__caption">
    <div class="albums__caption--name mb-md">Koyu Antoloji</div>
    <div class="albums__caption--year">2017</div>
  </figcaption>
</figure>
