Question

这是我的代码，HTML和body具有body类，然后在其中有一个div具有背景图像，在其中有一个div具有颜色覆盖层，最后在其中有一个登录表单。我已在页面中滚动，如何删除它并且有一个页面没有滚动。对于我来说，重要的是要确保所有介质尺寸均正确。

.bg-image{
  background: url("../images/666664.jpg") ;
  height: 100%;
  position: relative;
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
}

.body{
  height: 100%;
  margin: 0;
  font: 400 15px/1.8 "Lato", sans-serif;
  color: white!important;
}

.color-overlay {
  position: relative;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: #0d235b;
  opacity: 0.6;
}

Answer 1

我的猜测是，由于<div class="container"> <div class="row no-gutters justify-content-center"> <div class="col-sm-4"> <img src="https://via.placeholder.com/400X400" class="img-fluid"> </div> <div class="col-sm-4 text-center bg-dark text-white align-self-center"> <h4>Awesome desk</h4> </div> </div> </div> / form在.container div之外，因此无法正常工作。

.color-overlay

.bg-image{
  background: url("../images/666664.jpg") red;
  height: 100%;
  position: relative;
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
}

.body{
  height: 100%;
  margin: 0;
  font: 400 15px/1.8 "Lato", sans-serif;
  color: white!important;
}

.color-overlay {
  position: relative;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: #0d235b;
  opacity: 0.6;
}
