When one column takes up col-md-4 and another takes up col-md-8, the second with an image does not fill the width completely, leaving gaps on the left and right sides. Can anyone provide advice on how to remove these gaps and make the image full size? Thank you. Here is a screenshot for reference: https://i.sstatic.net/YZr86.png
.upperDiv{
height: 100px;
width: 100%;
background: red;
margin-top: 20px;
margin-bottom: 20px;
}
.fixed-content {
width: 100%;
height: 100px;
object-fit: cover;
}
<div class="container">
<div class="row upperDiv">
<div class="col-md-4" style="background: #005AA1;">
</div>
<div class="col-md-8">
