Bootstrap 4 Full height and width two columns - html

Question

I'm trying to create a layout like following using bootstrap 4.
Following is my JSFiddle and I think the approach I have taken is incorrect and there's a better way of doing this. And also there are responsive issues.
JSFiddle
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"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="container-fluid h-100 ">
<div class="row justify-content-center h-100">
<div class="col-4 hidden-md-down yellow" id="yellow">
Form Goes Here
</div>
<div class="col-10 col-sm-10 col-md-8 col-lg-8 col-xl-8 red">
Background image
</div>
</div>
</div>

bootstrap grid has 12 column and your total was coming to 14. I have added
col-sm-4 to yellow div and col-sm-8 to red div.

Bootstrap columns must add up to 12, yet yours add up to 14 for some viewports.What you probably want is to have one column at 4 and one at 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>

The better option is to just use .col for the red region so that it occupies the remaining width.
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">

</div>
<div class="col red">
