Recently, I decided to play around with the container, container-fluid, and jumbotron classes in Bootstrap 4. Here is the snippet of HTML code I used:
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
</head>
<body>
<h1 class="container">Lorem ipsum dolor sit amet</h1>
<h1 class="container-fluid">consectetur adipiscing elit</h1>
<span class="jumbotron">suspendisse potenti</span>
</body>
</html>
After running this code, I observed that the span element with the jumbotron class was slightly overlapping the h1 element with the container-fluid class. I am now curious to know if this overlap occurred due to a bug in Firefox Quantum or if it's related to some property within the jumbotron or container-fluid classes in Bootstrap 4.
