Css 如何在引导中创建Parrallax封面

我无法创建Parralax封面

.divcover {
border: #cccccc solid 1px;
background-attachment: fixed;
background-position: center center;
background-repeat: no-repeat;
min-height: 200px;
vertical-align: bottom;
border: none;
border-radius: 4px 4px 0 0;
margin-top: 20px;
/*margin-bottom: 20px;*/

}

}
