With sass-cli

1. Install Sass #

In your terminal, create a new folder called mybulma, navigate to it, then install the Sass gem:

gem install sass

To try it out, run sass -v and you should see the following:

Sass 3.5.3 (Bleeding Edge)

If you are on Windows and use Chocolatey, you can try choco install sass.

If you are on Mac and use Homebrew, you can try brew install sass/sass/sass.

2. Download Bulma #

Get the latest version of Bulma:

Download

Unzip it and put the bulma-0.7.1 folder inside your mybulma folder.

3. Create a Sass file #

Create a sass folder in which you add a file called mystyles.scss:

@charset "utf-8";
@import "../bulma-0.7.1/bulma/bulma.sass";

Make sure to write the correct path to the bulma.sass file.

4. Create an HTML page #

Create an HTML template which uses several Bulma components.

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>My custom Bulma website</title>
    <link rel="stylesheet" href="css/mystyles.css">
  </head>
  <body>
     <h1 class="title">
        Bulma
      </h1>

      <p class="subtitle">
        Modern CSS framework based on <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flexible_Box_Layout/Basic_Concepts_of_Flexbox">Flexbox</a>
      </p>

      <div class="field">
        <div class="control">
          <input class="input" type="text" placeholder="Input">
        </div>
      </div>

      <div class="field">
        <p class="control">
          <span class="select">
            <select>
              <option>Select dropdown</option>
            </select>
          </span>
        </p>
      </div>

      <div class="buttons">
        <a class="button is-primary">Primary</a>
        <a class="button is-link">Link</a>
      </div>
  </body>
</html>

Save this file as mypage.html.

Notice the css/mystyles.css path for your stylesheet. This will be the location of the CSS file we will generate with Sass.

Open the page in your browser:

5. Build the CSS file #

In your terminal, type the following command:

sass --sourcemap=none sass/mystyles.scss:css/mystyles.css

Reload the page and it should be styled like this:

Bulma default styles — Bulma's default styles

To watch for changes, just launch the following command:

sass --watch --sourcemap=none sass/mystyles.scss:css/mystyles.css

6. Add your own Bulma styles #

Replace the content of the mystyles.scss file with the following:

    @charset "utf-8";

// Import a Google Font
@import url('https://fonts.googleapis.com/css?family=Nunito:400,700');

// Set your brand colors
$purple: #8A4D76;
$pink: #FA7C91;
$brown: #757763;
$beige-light: #D0D1CD;
$beige-lighter: #EFF0EB;

// Update Bulma's global variables
$family-sans-serif: "Nunito", sans-serif;
$grey-dark: $brown;
$grey-light: $beige-light;
$primary: $purple;
$link: $pink;
$widescreen-enabled: false;
$fullhd-enabled: false;

// Update some of Bulma's component variables
$body-background-color: $beige-lighter;
$control-border-width: 2px;
$input-border-color: transparent;
$input-shadow: none;

// Import only what you need from Bulma
@import "../node_modules/bulma/sass/utilities/_all.sass";
@import "../node_modules/bulma/sass/base/_all.sass";
@import "../node_modules/bulma/sass/elements/button.sass";
