css3 - Apply a CSS filter only on background -


in following snippet, have applied blur filter on .sub-menu text filtered.

how can apply blur filter only on background , not text?

.sub-menu {    list-style: none;    position: relative;    float: left;    margin: 0px;    padding-left: 0px;    z-index: 1;  }  .sub-menu li {    display: block;    color: #888888;    text-decoration: none;    font-size: 14px;    line-height: 32px;    padding: 0 12px;  }  .sub-menu li a:hover {    color: black;  }  .sub-menu {    position: absolute;    top: 100%;    left: 0;    -webkit-filter: blur(10px);  /* chrome, opera */    -moz-filter: blur(10px);    -ms-filter: blur(10px);    filter: blur(10px);    padding: 0  }
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css" rel="stylesheet" />  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet" />    <ul class="nav navbar-nav">    <li><a href="#">edit book</a>      <ul class="sub-menu">        <li><a href="#">new</a>          <li><a href="#">browse</a>            <li><a href="#">approval</a>      </ul>      </li>  </ul>

you can apply blur filter on pseudo element , stack behind .sub-menu content :

.sub-menu {    list-style: none;    position: relative;    float: left;    margin: 0px;    padding-left: 0px;    z-index: 1;  }  .sub-menu li {    display: block;    color: #888888;    text-decoration: none;    font-size: 14px;    line-height: 32px;    padding: 0 12px;  }  .sub-menu li a:hover {    color: black;  }  .sub-menu {    position: absolute;    top: 100%;    left: 0;    padding: 0  }  .sub-menu:after {    content: '';    position: absolute;    left: 0;    top: 0;    width: 100%;    height: 100%;    z-index: -1;    background:url('http://lorempixel.com/output/nature-q-c-640-480-6.jpg');    background-size:cover;    -webkit-filter: blur(10px);    /* chrome, opera */    -moz-filter: blur(10px);    -ms-filter: blur(10px);    filter: blur(10px);  }
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css" rel="stylesheet" />  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet" />    <ul class="nav navbar-nav">    <li><a href="#">edit book</a>      <ul class="sub-menu">        <li><a href="#">new</a>          <li><a href="#">browse</a>            <li><a href="#">approval</a>      </ul>      </li>  </ul>
