在模糊背景 div 中取消模糊内容

Question

所以我真的很喜欢https://www.w3schools.com/howto/howto_css_blurred_background.asp 的这种特殊效果，您可以在其中模糊背景并显示文本。我目前遇到的问题是我想在我的第一个内容下方为我的第二个内容添加另一个壁纸。第一个内容不错。现在我希望我的第二个内容在您滚动时出现在第二个壁纸中。有点像创建视差效果，但我正在创建自己独特的网站。

这一次我想要一个模糊的背景（第二张壁纸），同时将我想要的东西放在我想要的位置并让它聚焦。

有没有办法做到这一点？

从bg-image2 开始，我想要h1 和p，在bg-image2 内聚焦模糊的背景图像。

注意： 壁纸不会显示在下面的 sn-p 中，因为我已经在位于我的计算机中的文件夹中找到了我需要的图片.

body,
html {
  height: 100%;
}

* {
  box-sizing: border-box;
}

.bg-image {
  /* The image used */
  background-image: url("images/wallpaper1.jpg");
  /* Add the blur effect */
  filter: blur(8px);
  -webkit-filter: blur(8px);
  /* Full height */
  height: 100%;
  /* Center and scale the image nicely */
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
}


/* Position text in the middle of the page/image */

.bg-text {
  background-color: rgb(0, 0, 0);
  /* Fallback color */
  background-color: rgba(0, 0, 0, 0.4);
  /* Black w/opacity/see-through */
  color: white;
  font-weight: bold;
  border: 3px solid #f1f1f1;
  position: absolute;
  top: 50%;

  transform: translate(-50%, -50%);

.bg-image2 {

  /* Add the blur effect */
  filter: blur(8px);
  -webkit-filter: blur(8px);

<div class="bg-image"></div>

<div class="bg-text">

<div class="bg-image2">

  <!-- This is the part where I want my stuff to not be blurred and focus -->
    
  <div class="profilePicture">
    <img src="images/profilePic.jpg" style="width: 170px; height: 170px; border-radius:50%;">
    <h1>This is a title</h1>
    <p>This is just a paragraph</p>
  </div>

</div>

Answer 1

这是您正在寻找的结果吗？

我所做的只是围绕bg-image2 和profilePicture 创建一个div，这样bg-image2 上的模糊就不会影响profilePicture，然后将该div 设置为position:relative;，这样@ 987654327@ 可以像你一样放在中间。

这是您编辑的 HTML：

<div class="bg-image"></div>

<div class="bg-text">
    <h1>My name is Stackoverflow</h1>
    <p>And I am a website</p>
</div>

<div class="bg-test">
  <div class="bg-image2">

    <!-- This is the part where I want my stuff to not be blurred and focus -->

  </div>

  <div class="profilePicture">
      <img src="https://images.pexels.com/photos/1253661/pexels-photo-1253661.jpeg?cs=srgb&dl=android-wallpaper-bluhen-blume-1253661.jpg&fm=jpg" style="width: 170px; height: 170px; border-radius:50%;">
      <h1>This is a title</h1>
      <p>This is just a paragraph</p>
    </div>
</div>

还有 CSS：

body,
html {
  height: 100%;
}

* {
  box-sizing: border-box;
}

.bg-image {
  /* The image used */
  background-image: url("https://images.unsplash.com/photo-1507608616759-54f48f0af0ee?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80");
  /* Add the blur effect */
  filter: blur(8px);
  -webkit-filter: blur(8px);
  /* Full height */
  height: 100%;
  /* Center and scale the image nicely */
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
}


/* Position text in the middle of the page/image */

.bg-test {
  position:relative;
}

.bg-text {
  background-color: rgb(0, 0, 0);
  /* Fallback color */
  background-color: rgba(0, 0, 0, 0.4);
  /* Black w/opacity/see-through */
  color: white;
  font-weight: bold;
  border: 3px solid #f1f1f1;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  z-index: 2;
  width: 80%;
  padding: 20px;
  text-align: center;
}

.bg-image2 {
  /* The image used */
  background-image: url("https://whatthenewsblog.files.wordpress.com/2015/03/ecl-ann.jpg");
  /* Add the blur effect */
  filter: blur(8px);
  -webkit-filter: blur(8px);
  /* Full height */
  height: 100vh;
  /* Center and scale the image nicely */
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
}

.profilePicture {
  position: absolute;
  left: 50%;
  top:50%;
  margin: 0 auto;
  transform: translate(-50%, -50%);
}

Answer 2

我遇到了类似的问题。经过大量搜索，我找到了完美的解决方案。 你可以使用backdrop-filter。

您的代码：

body,
    html {


      height: 100%;
    }
    
    * {
        padding: 0px;
        margin: 0px;
      box-sizing: border-box;
    }
    
    .bg-image {
      /* The image used */
      background-image: url("https://images.unsplash.com/photo-1507608616759-54f48f0af0ee?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80");
      /* Add the blur effect */
      
      /* Full height */
      height: 100%;
      /* Center and scale the image nicely */
      background-position: center;
      background-repeat: no-repeat;
      background-size: cover;
    }
    
    
    /* Position text in the middle of the page/image */
    
    .bg-test {
      position:relative;
    }
    
    .bg-text {
      background-color: rgb(0, 0, 0);
      /* Fallback color */
      background-color: rgba(0, 0, 0, 0.4);
      /* Black w/opacity/see-through */
      color: white;
      font-weight: bold;
      backdrop-filter: blur(8px);
      border: 3px solid #f1f1f1;
      position: absolute;
      top: 50%;
      left: 50%;
      transform: translate(-50%, -50%);
      z-index: 2;
      width: 80%;
      padding: 20px;
      text-align: center;
    }
    
    .bg-image2 {
      /* The image used */
      background-image: url("https://blog.prezi.com/wp-content/uploads/2019/03/patrick-tomasso-208114-unsplash-1024x768.jpg");
      /* Add the blur effect */
      /* Full height */
      height: 100vh;
      /* Center and scale the image nicely */
      background-position: center;
      background-repeat: no-repeat;
      background-size: cover;
    }
    
    .profilePicture {
      backdrop-filter: blur(8px);
      height: 100vh;
      width: 100vw;
      display: flex;
      flex-direction: column;
      justify-content: center;
      align-items: center;
      position: absolute;
      left: 50%;
      color: white;
      top:50%;
      margin: 0 auto;
      transform: translate(-50%, -50%);
    }

<div class="bg-image">

<div class="bg-text">
    <h1>My name is Stackoverflow</h1>
    <p>And I am a website</p>
</div>
</div>

<div class="bg-test">
  <div class="bg-image2">

    <!-- This is the part where I want my stuff to not be blurred and focus -->
    <div class="profilePicture">

  </div>

我知道你已经很久没有问过了，而且你得到了答案。 希望这对其他人有帮助:)
