背景图像 :hover but not on text 上的 Css 模糊

Question

例如:https://jsfiddle.net/q4871w6L/

.article-image {
  height: 150px;
  width: 238px;
  -webkit-filter: grayscale(0) blur(0);
  filter: grayscale(0) blur(0);
  transition: .4s ease-in-out;
}
.article-image:hover {
  -webkit-filter: grayscale(100%) blur(2px);
  filter: grayscale(100%) blur(2px);
  transition: .4s ease-in-out;
}
.ar-image {
  position: relative;
  width: 238px;
  height: 150px;
}
.article-image > p {
  display: none;
}
.article-image:hover > p {
  position: absolute;
  top: 40%;
  display: block;
  color: #ffffff;
  font-size: 16px;
  font-weight: bold;
  width: 100%;
  height: 100%;
  text-align: center;
  transition: .4s ease-in-out;
}

<div class="ar-image">
  <div style="background: url('http://maximumwallhd.com/wp-content/uploads/2015/06/fonds-ecran-plage-palmier-12-660x330.jpg')" class="article-image">
    <p>Lire plus</p>
  </div>
</div>

我试图在悬停时模糊背景而不是图像上的文本。 如何在不模糊图像上的文字的情况下模糊背景图像？

感谢

.article-image{
    height: 150px;
    width: 238px;
    -webkit-filter: grayscale(0) blur(0);
    filter: grayscale(0) blur(0);
    transition: .4s ease-in-out;
}

.ar-image:hover .article-image{
    -webkit-filter: grayscale(100%) blur(2px);
    filter: grayscale(100%) blur(2px);
    transition: .4s ease-in-out;
}

.ar-image{
    position: relative;
    width: 238px;
    height: 150px;
}

.ar-image > p{
    display: none;
}

.ar-image:hover > p{
    position: absolute;
    top: 0;
    display: block;
    color: #ffffff;
    font-size: 16px;
    font-weight: bold;
    z-index: 0;
    width: 100%;
    height: 100%;
    text-align: center;
    transition: .4s ease-in-out;
    line-height:150px;
    margin:0;
}

<div class="ar-image">
     <div style="background: url('http://maximumwallhd.com/wp-content/uploads/2015/06/fonds-ecran-plage-palmier-12-660x330.jpg')" class="article-image"></div>
       <p>Lire plus</p>
  </div>

注意: 由于文本是绝对定位的，我已将其从背景容器中移除并放置在外部。

并为主容器('.ar-image')添加了 :hover 事件。
