Issue in fixing the content in the center both horizontally and vertically

Narwen Source

I am having problem fixing my content in the center both vertically and horizontally. And my container-fluid doesn't cover footer when I inspect in the developer tools. I have looked across other stacks but still can't figure it out. Here is my codepen. https://codepen.io/anon/pen/yqdbWd

What I want is to remove the sidebar since its a single page with few contents. I have included the screenshots of my issue.enter image description here And my container-fluid doesn't take up the whole page.enter image description here Lastly, I want to know if there is way to shorten the length of my hr line like this much.enter image description here

And here is the code I have done so far.

HTML

<body>
<div class="container-fluid h-100">
        <nav class="navbar navbar-light rounded">
    <a class="navbar-brand" href="#">

    <ul class="nav justify-content-end">

          <div class="jumbotron text-center">
              <hr class="text-border" />
              <p class="lead">Perth says tuned on it.</p>
              <p class="lead">Stay Alert For Updates</p>
              <hr class="text-border" />
          </div>
      </div>
  </div>

   <footer class="mt-auto">
    <p class="float-left">2018 © Palungo</p>
      <div class="float-right">

And here is the CSS

  .jumbotron{ background: none; }
  .text-border{
     display: block;
     height: 1px;
     border: 0;
     border-top: 4px solid #F3B0B6;
    }
   .lead{

You added height: 100%; to your main section which will make it as large as the screen but the header pushed your main section down which is why the scrollbar appeared.

Then I added position: absolute; to your footer to make it stick to the bottom and added display: flex; with some few tricks to replace the float: left & float: right.

Also to shorten the lines I replaced <div class="col-4 mx-auto"> with <div class="col-6 mx-auto"> if you want to shorten it even more use <div class="col-3 mx-auto"> or even a lower value.

body,
html {
  height: 100%;
  background: #333A4D;
}

.navbar {
  margin: 10px;
  background: #333A4D;
  padding: 20px;
  margin-top: 0px;
}

.nav-link {
  font-size: 25px;
  line-height: 32px;
  color: #F3B0B6;
}

.nav-item {
  margin-left: 1rem;
}

.list-inline-item {
  margin-left: 1rem;
}

.jumbotron {
  background: none;
}

.text-border {
  display: block;
  height: 1px;
  border: 0;
  border-top: 4px solid #F3B0B6;
}

.lead {
  text-transform: uppercase;
  color: #F3B0B6;
  font-size: 25px;
  line-height: 31px;
}

@media (min-width: 48em) {
  .navbar-brand {
    float: left;
  }
  .nav {
    float: right;
  }
}

.footer {
  width: 100%;
  position: absolute;
  bottom: 0;
  left: 0;
  padding: 0 40px;
  display: flex;
  justify-content: space-between;

.centered-content {
  position: absolute;

Instead of using height:100% on the jumbotron .row, make it's container-fluid flexbox column (d-flex flex-column) and then flex-grow-1 on the jumbotron .row so that is fills the remaining height between the nav and footer. This will eliminate the scrollbar.

   <div class="container-fluid h-100 d-flex flex-column">
      <nav class="navbar navbar-light fixed-top">
        ..
      </nav>
      <div class="row align-items-center flex-grow-1">
          <div class="col-6 mx-auto">
              <div class="jumbotron text-center mb-0">
                  <hr class="text-border" />
                  <p class="lead">Perth says tuned on it.</p>
                  <p class="lead">Stay Alert For Updates</p>
                  <hr class="text-border" />
              </div>
          </div>
      </div>
      <footer class="mt-auto">
        ..
      </footer>
    </div>

As far as centering the jumbotron on the page, make the navbar fixed-top so that it's not pushing down the jumbotron content and making it off-center. Also remove the bottom margin on the jumbotron (mb-0). Here is a generic Bootstrap 4 example
