Answer 2

Bootstrap列必须总计为12，而对于某些视口，您的总计必须为14。
您可能想要的是在4拥有一列，而在在8：

.left, .right {
  height: 100vh;
}

.left {
  background: yellow;
}

.right {
  background: red;
}

<div class="row">
  <div class="col-4 left"></div>
  <div class="col-8 right"></div>
</div>

Answer 3

更好的选择是将.col用于红色区域，使其占据剩余宽度。

html,
body {
  height: 100%;
}

.yellow {
  background-color: yellow;
}

.red {
  background-color: red;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet" />
<div class="container-fluid h-100">
  <div class="row h-100">
    <div class="col-4 hidden-md-down yellow" id="yellow">
      Form Goes Here
    </div>
    <div class="col red">
      Background image
    </div>
  </div>
</div>
