Align element vertically below Navbar

Question

I have a page that I’m going to split into two columns. The right column should be aligned both vertically and horizontally and cannot create a scroll bar. I managed to do this, but as there is a navbar, the second column is getting bigger than the screen size, thus creating the scroll bar. How do I center this column vertically without creating the scroll bar, taking into account the size of my navbar?

html, body{
	height: 100%;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" rel="stylesheet"/>

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
    </ul>
  </div>
</nav>


<div class="container h-100">
  <div class="row h-100">
    <div class="col">
      <p class="bg-white">Coluna 1</p>
    </div>
    <div class="col d-flex bg-info justify-content-center align-items-center">
      <p class="bg-white">Coluna 2</p>
    </div>
  </div>
</div>

Answer 1

I haven’t found a "default" way to do this... I mean without needing extra CSS...

But as you have a standard height for the Navbar, just take that time out of height total... thus making a calc of (100% - Height da Navbar) vc "remove" the scroll

See Example, notice that I put the height of .container with class .altura the height stays height: calc(100% - 56px); where 56px is the time of navbar.

html, body{
    height: 100%;
}
.container.altura {
    height: calc(100% - 56px);
}
