I have started to learn Bulma. I want to minimize container's (grey area in the picture) size in x-axis so I can embed elements into.Couldn't find any related content in documents. Here is my source code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" it>
<title>Title</title>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bulma/0.7.1/css/bulma.css">
</head>
<body>
<section class="hero is-medium">
<div class="hero-body has-background-danger">
<nav class="navbar has-background-primary">
<div class="container has-background-grey-light is-fluid ">
</div>
</nav>
</div>
</section>
</body>
</html>
