这是我的主页

我想扩展图像的高度以适应整个屏幕。我知道我必须调整height属性，我这样做，似乎没有任何效果。

CSS 

.hero {
  background: #fff;
  border-bottom: 8px solid #7ac9ed;
  background: url('../img/hero-slider/boxfill2sm.jpg');
  background-size: cover;
  position: relative;
  padding-top: 0;
  height: auto;
}

注意：我尝试了height: auto;。它没有做任何事情。

HTML 

<section class="hero">
    <div class="container-fluid no-margin no-padding">

        <div class="col-md-8 col-sm-12 col-xs-12 col-lg-8" id="hero-left">

您需要确定屏幕高度，以便更好地使用screen.height 可以使用jQuery访问。此外，如果您使用$( window ).height();，则可以使用$(document).ready(function() { h=$(window).height(); $('.hero').css({'height':h+'px'}); });

获取此属性 
auto increment

  background: url(j.jpg) no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  position: relative;
  padding-top: 0;
  height: 100%;
