你可以使用这个 HTML

 <div class="content">
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>
    Loriem ispsum is simply dummy text<br>

     <div class="gradientback">

     </div>
</div>

有了这个 CSS

 body{background:#000;}
.content{
    width:500px;
    height:300px;
    position:relative;
    color:#fff;
    overflow:hidden;
}
.gradientback{

    position:absolute;
    bottom:0px;
    left:0px;
    width:100%;
    height:50px;
    background: -moz-linear-gradient(top,  rgba(137,255,241,0) 0%, rgba(0,0,0,1) 100%); /* FF3.6+ */
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(137,255,241,0)), color-stop(100%,rgba(0,0,0,1))); /* Chrome,Safari4+ */
    background: -webkit-linear-gradient(top,  rgba(137,255,241,0) 0%,rgba(0,0,0,1) 100%); /* Chrome10+,Safari5.1+ */
    background: -o-linear-gradient(top,  rgba(137,255,241,0) 0%,rgba(0,0,0,1) 100%); /* Opera 11.10+ */
    background: -ms-linear-gradient(top,  rgba(137,255,241,0) 0%,rgba(0,0,0,1) 100%); /* IE10+ */
    background: linear-gradient(to bottom,  rgba(137,255,241,0) 0%,rgba(0,0,0,1) 100%); /* W3C */
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#0089fff1', endColorstr='#000000',GradientType=0 ); /* IE6-9 */

}
