html - 仅缩放背景图像

Question

我只想缩放背景图片

.prod_img:hover {
  webkit-transform: scale(1.04);
  -moz-transform: scale(1.04);
  -o-transform: scale(1.04);
  -ms-transform: scale(1.04);
  transform: scale(1.04);
  -webkit-transition: all 2s ease-in-out;
  -moz-transition: all 2s ease-in-out;
  -o-transition: all 2s ease-in-out;
  -ms-transition: all 2s ease-in-out;
  transition: all 2s ease-in-out;
}

.prod_img {
  content: ' ';
  -webkit-transition: all 2s ease-in-out;
  -moz-transition: all 2s ease-in-out;
  -o-transition: all 2s ease-in-out;
  -ms-transition: all 2s ease-in-out;
  transition: all 2s ease-in-out;
  height: 580px;
  width: 300px;
}

.protransparentbg {
  position: absolute;
  background: rgba(51, 51, 51, .8);
}

<<div id="prod_main">
  <div id="product_content">

    <li class="prod_img prod_img1" id="prod_img1" style="background-image: url(http://images.all-free-download.com/images/graphicthumb/beautiful_landscape_picture_02_hd_pictures_166284.jpg);background-size: cover;background-position: center center;">
      <div class="protransparentbg">
        <h4 class="">FIBER FLOOR MAT</h4>
      </div>
    </li>



  </div>
  </div>

这是我的代码，但在此缩放效果适用于背景图像，它还会影响图像中的内容。如何仅对背景图像赋予效果。

Answer 1

你必须更改 css 部分并使用 伪元素 来获取它

去掉html部分的background-image，在css中使用伪元素

.prod_img {
  -webkit-transition: all 2s ease-in-out;
  -moz-transition: all 2s ease-in-out;
  -o-transition: all 2s ease-in-out;
  -ms-transition: all 2s ease-in-out;
  transition: all 2s ease-in-out;
  height: 580px;
  width: 300px;
  position: relative;
}

.prod_img:before {
  content: ' ';
  position: absolute;
  top: 0px;
  left: 0px;
  width: 100%;
  height: 100%;
  background-image: url(http://images.all-free-download.com/images/graphicthumb/beautiful_landscape_picture_02_hd_pictures_166284.jpg);
  background-size: cover;
  background-position: center center;
  "

}

.protransparentbg {
  position: absolute;
  left: 20px;
  background: rgba(51, 51, 51, .8);
}

.prod_img:hover:before {
  webkit-transform: scale(1.04);
  -moz-transform: scale(1.04);
  -o-transform: scale(1.04);
  -ms-transform: scale(1.04);
  transform: scale(1.04);
  -webkit-transition: all 2s ease-in-out;
  -moz-transition: all 2s ease-in-out;
  -o-transition: all 2s ease-in-out;
  -ms-transition: all 2s ease-in-out;
  transition: all 2s ease-in-out;
}

<div id="prod_main">
  <div id="product_content">
    <li class="prod_img prod_img1" id="prod_img1">
      <div class="protransparentbg">
        <h4 class="">FIBER FLOOR MAT</h4>
      </div>
    </li>
  </div>
</div>
