Bootstrap Div 或 Container 覆盖背景图片

Question

我有这个问题，我的页面样式带有 bootstrap div 容器用于登录表单和顶部徽标，但是这部分覆盖或空白了我使用 [= 设置样式的预期背景图像24=]

html{
  background: url("Bg1.jpg")no-repeat center fixed;
  -webkit-background-size:cover;
  -moz-background-size:cover;
  -o-background-size:cover;
  background-size:cover;
  margin:0;
}

还有我的 2 个容器，我在上面放了一个徽标，中间是登录表单

<div class="container"><!--top portion-->
  <div class="row"> <!--logo portion-->
<div class="col-sm-3 col-xs-12">
  <a href="#"><img class="image-responsive img-rounded" alt="B-Flight" src="Logo1.png" id="banner" /></a>
</div>
<div class="col-sm-3 col-xs-0"></div>
<div class="col-sm-3 col-xs-0"></div>
<div class="col-sm-3 col-xs-0"></div>
</div><!--row-->

  <div class="container">
  <div class="row">
<div class="col-xs-12 col-sm-4"></div><!--left column of whole page-->
<div class = "col-xs-12 col-sm-4">
<title>Login</title>
  <form class="form-signin">
    <h2 class="form-signin-heading align-center">Sign In</h2>
    <label for="usrName" class="Titlefont">User Name</label>
    <input type="text" id="usrName" class="form-control" placeholder="user name" required autofocus><br>
    <label for="inputPassword" class="sr-only">Password</label>
    <input type="password" id="inputPassword" class="form-control" placeholder="Password" required>
    <div class="checkbox">
      <label>
        <input type="checkbox" value="remember-me"> Remember me
      </label>
    </div>
    <button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
    <br>
    <a href="signup.html"><button class="btn btn-link btn-block" type="button">Not registered? Sign up now</button></a>
  </form>
</div><!--set alignment-->
<div class="col-xs-12 col-sm-4"></div><!--right column of the page-->
</div><!--row-->
</div> <!-- /container -->

默认情况下，body 的背景色设置为白色。因此，当您为 html 设置样式时，body 没有针对性且仍然是白色。您可能想尝试使用

html, body {
    /* Your CSS goes here */
}

这应该可以解决您的问题。
