Use Bulma in a Meteor React project

Can anyone tell how to use Bulma in Meteor?
If I simply include it inside HEAD tag it doesn’t update automatically my running instance when I change a class in a HTML tag:

  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>Hello Bulma!</title>
  <link rel="stylesheet" href="">
  <script defer src=""></script>
<section class="section">
  <div class="container">
    <h1 class="title is-1">
      Hello World
    <p class="subtitle">
      My first website with <strong>Bulma</strong>!
    <button class="button is-danger">Save me</button>

Now change is-danger to is-primary and save. It happens that you have to refresh the page manually to see the change
