Just another SCSS/CSS framework.

Usage no npm install needed!

<script type="module">
  import unistylusCore from 'https://cdn.skypack.dev/@unistylus/core';



An SCSS/CSS theming system.

What is this?

This is just another UI framework that nobody want to use, but me, or isn't it?

It is an effort of unifying the web UI development experience:

  • 💚 Just standard HTML, CSS/SCSS & JS (when needed).
  • 🌓 Supports multiple skins in app runtime.
  • 👌 No icon fonts; only register whatever icons you ever need.
  • ⚡ Imports just the parts you want.
  • 🔨 Customize to the bone, at microscopic level.
  • 🔌 Replacement (-ish) for other frameworks.
  • 😍 A member of the Lam Nhan Ecosystem.

Install and usage


  • Step 1: Install the core
npm i @unistylus/core
  • Step 2: Install a collection (see list)
npm i @unistylus/boostrap
  • Step 3: Create a file in src/unistylus.scss
@import '@unistylus/bootstrap/skins/light-default';
@import '@unistylus/bootstrap/reset';
@import '@unistylus/bootstrap/core';
@import '@unistylus/bootstrap/content/typography';
@import '@unistylus/bootstrap/components/button';

In the context of the Unistylus framework, these terms have their special meaning.

  • SKIN: a look of a UI (colors, sizes, fonts, ...)
  • SOUL: a feel of a UI (Bootstrap, Material, ...)
  • THEME: a combination of a SKIN (a look) or multiple skins + a SOUL (a feel)

Add new skins

Add this to the global style file (ex.: styles.scss for Angular apps):

[data-theme=name] {
  // add properties here

Apply app skins

Apply skin in runtime:

document.body.setAttribute('data-theme', 'name');

Use icons

Register icons globally, see styles.scss for example:

@import '@unistylus/core';

$icons: (
  menu: ('bootstrap', 'list', 'latest'),
  github: ('bootstrap', 'github', 'latest')

@include register_icons($icon);

To use registered icons, in component .html:

<i class="icon icon-menu"></i>

There are also built-in icon packs:

To access buit-in icon url, use the variable $[icon_pack]_icons:

@import '@unistylus/core';

$light_theme_icons: (
  menu: '#{$bootstrap_icons}/light/list.svg'


Level 1

To customize a skin (see styles.scss for example). Place this under the skin imports:

@import 'path/to/a/skin';

[data-theme=name] {
  // place properties here

Level 2

To customize a soul, override its CSS:

@import 'path/to/a/soul';

.button {
  // override anything

Level 3

Provide you own skin and soul, overall its just HTML & CSS, so you can do whatever you want.

@import 'path/to/your/own/skin';
@import 'path/to/your/own/soul';

Custom properties

To add your own properties:

@import '@unistylus/core';

$shared_properties: ();

$light_theme_properties: (
  foo: 'Foo',
  bar: 'Bar',

$dark_theme_properties: (
  foo: 'Foo',
  bar: 'Bar',

@include register_theme_properties(
    light: $light_theme_properties,
    dark: $dark_theme_properties,
    default: merge-map($shared_properties, $light_theme_properties),


See the list of mixins.
