title: Bootstrap 5.1.3: 3rem in margin-top in row descendants
body: <p>I installed bootstrap 5.1.3 with npm in a project. I built a page with the tipical bootstrap classes, but every '.row &gt; * ' has a margin-top: 3rem; and I don't know why, and how to avoid it. Where has my configure ruined?</p>
  <p>My local app.scss is like this, I haven't import any local scss yet.</p>
  <pre><code>@import '~bootstrap/scss/bootstrap.scss';
  </code></pre>
  <p>But in the compiled app.css the .row &gt; * has a margin-top: 3rem, and I dont know why:</p>
  <pre><code>.row &gt; * {
  ...
    margin-top: 3rem;
  }```
  
  Is this the normal behavior of bootstrap 5.1.3?
