And here is what I get... I tried adding rows/columns but they only affect the movement from top to bottom, I used to be able to place a column/row on the left side of the jumbotron but now I can't anymore... Is there something that I'm missing with columns and rows?
Here is my code:
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Mailsafe</title>
<link rel="stylesheet" href="bootstrap.min.css" />
<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Bitter:400,700" />
<link rel="stylesheet" href="Header-Dark.css" />
<link rel="stylesheet" href="styles.css" />
</head>
<body id="hero" style="background-color:#004878;">
<section class="d-flex mse spacer" id="hero">
<div id="hero-top"></div>
<div id="hero-bottom"></div>
</section>
<div>
<div class="container">
<div class="row">
<div class="col">
<div class="jumbotron flex-grow-0 flex-shrink-1" id="gateway">
<h1 class="text-center">Company Name</h1>
<p class="text-center"><br />Company blah blah<br />company blah blah blah.<br /><br /></p>
<p class="text-center"><a class="btn btn-primary" href="#" style=" width:673px;
">Get Started →</a></p>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
Add 100% height on the body and html and d-flex h-100 align-items-center
classes on the container's wrapping div. Additionally remove width from the Get started anchor and add display block to it.
html,
body {
height: 100%;
margin: 0;
}
