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

SCSS

• 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';

• Step 4 (OPTIONAL): To use minxins

@import '@unistylus/core';

CDN

Terminology

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:

• Bootstrap: @unistylus/bootstrap-icons
• Material: @unistylus/material-icons
• Fluent: @unistylus/fluent-icons

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

@import '@unistylus/core';

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

Customization

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),
  )
);
