Having trouble articulating my issue, so here's a video that should clarify: https://example.com/video

I'm using a bootstrap carousel template for a full-width slider. Despite my efforts to remove the white-space transitions, they persist. Am I overlooking something obvious in my code?

HTML:

<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<title></title>
<meta name="description" content="" />
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
<link rel="stylesheet" href="style.css" />

<header>
  <div class="header-upper container-fluid d-flex flex-row justify-content-center">
    <div class="logo m-3">
      <img src="images/v.png" />
    </div>
    <div class="header-upper-text m-2">
      <h1>This is the Title</h1>
      <h3>This is the description</h3>
