html - 我的视差图像对移动设备/Bootstrap 没有响应

Question

当我的屏幕宽度为 682PX 时，我的图像宽度没有覆盖在屏幕上，它开始消失。它显然没有响应，我不知道为什么。

我还在视差部分加入了一类“img-responsive”。这也没有用。

<section class="module parallax parallax-1" class="img-responsive">
  <div class="container">
    <h1>Services</h1>
  </div>
</section>

<section class="module content">
  <div class="container">
    <h2>Lorem Ipsum Dolor</h2>
      <p></p>
  </div>
</section>
</div> 

CSS:

section.module:last-child {
  margin-bottom: 0;
}
section.module h2 {
  margin-bottom: 40px;
  font-family: "Roboto Slab", serif;
  font-size: 30px;
}
section.module p {
  margin-bottom: 40px;
  font-size: 16px;
  font-weight: 300;
}
section.module p:last-child {
  margin-bottom: 0;
}
section.module.content {
  padding: 40px 0;
  height: 600px;
}
section.module.parallax {
  height: 600px;
  background-position: 50% 50%;
  background-repeat: no-repeat;
  background-attachment: fixed;
  background-size: cover !important; 
  margin-top: -30px;
}
section.module.parallax h1 {
  color: rgba(255, 255, 255, 0.8);
  font-size: 48px;
  line-height: 600px;
  font-weight: 700;
  text-align: center;
  text-transform: uppercase;
  text-shadow: 0 0 10px rgba(0, 0, 0, 0.2);
}

section.module.parallax-1 {
  background-image: url("../img/rolling.jpg");


}

Answer 1

检查 section.module.parallax-1 部分，我已经为这个类添加了背景功能。还删除了 section.module.parallax 类，因为它与结果有冲突，这是有问题的

section.module:last-child {
  margin-bottom: 0;
}
section.module h2 {
  margin-bottom: 40px;
  font-family: "Roboto Slab", serif;
  font-size: 30px;
}
section.module p {
  margin-bottom: 40px;
  font-size: 16px;
  font-weight: 300;
}
section.module p:last-child {
  margin-bottom: 0;
}
section.module.content {
  padding: 40px 0;
  height: 600px;
}

section.module.parallax h1 {
  color: rgba(255, 255, 255, 0.8);
  font-size: 48px;
  line-height: 600px;
  font-weight: 700;
  text-align: center;
  text-transform: uppercase;
  text-shadow: 0 0 10px rgba(0, 0, 0, 0.2);
}

section.module.parallax-1 {
  background-image: url("https://image.ibb.co/dquSd5/rolling.jpg");
  background-repeat:no-repeat;
background-size:contain;
  background-size: 100%;
top: 0;


}

<section class="module parallax parallax-1 img-responsive">
  <div class="container">

    <h1>Services</h1>
  </div>

<section class="module content">
  <div class="container">
    <h2>Lorem Ipsum Dolor</h2>
