fw.css

Funkwhale has a single stylesheet for all projects (Website, Docs, App) and for anyone who wants to use the Funkwhale design system.

Design system layers

Cross-browser sanitization makes sure every browser displays the design consistently.
Document styles give standard HTML elements such as <h1> a consistent look.
System tokens such as --block-size-32 define the building blocks of layouts and color scales.
System attributes such as ui-raised or ui-block-size="48" apply consistent spacing and contrasts.
System classes for Colors, layouts, fonts are useful for component developers - they can fine-tune which class combinations for a component.
Component style modules will override any system classes or attributes. Here is how to make components respect the user's theme, color-mode and accessibility presets:
- Reuse system tokens such as var(---color-background-200)
- Where possible, prefer system classes or attributes over component style modules
Custom style attributes override any rule. Note that you cannot use @container queries for responsive layouts here.

The system utilities defined in layers 3-5 are available as TypeScript objects for smoother dx.

All system utilities are customizable. Create a theme by overriding the rules [WIP]. Stick to the system utilities where possible to make your HTML or Vue template adapt to user preferences automatically.

Cross-browser sanitization

For cross-browser consistency, we use https://csstools.github.io/sanitize.css/ as the base layer. Check the comments in fw.css to see which version is pinned currently. We update the sanitize layer only once every few years - this part of CSS moves slowly.

The sanitize layer has lowest precedence: You can override all affected styles by adding rules to the document or system layers, or through component <style module>s.

Some colors give you an inverted palette:

class="color-blue-deep-solid"

class="color-destructive-solid"

Override the contrast

Each color ranges from -50 (lowest contrast) to -950 (highest contrast). The difference between two numbers approximately corresponds to their contrast ratio: --color-foreground-900 on --color-background-450 will have a contrast ratio of approximately 4.5:1. For WCAG2.2 compliance, keep small text and symbols at 4.5:1 and large text and decoration at 3:1.

When you give an element a color class and a fill class (class="color-primary-solid"), the design system calculates three palettes for you: --color-background-*, --color-foreground and a generic --color.

style="color: var(--color-foreground-400)"style="color: var(--color-foreground-600)"style="color: var(--color-foreground-800)"

class="color-blue-solid"

class="color-blue-solid" style="background-color: var(--color-background-150)"

Preset background/foreground combos and interactive states

{color}-solid: Adds a solid background. For pastel colors, a subtler shade is used. For accents, a default shade is retained. For primary and dangerous palettes, the background is tinted while the foreground is neutral (default).
{color}-ghost: Like solid, except that the background is only activated on interaction (:focus, :hover).
{color}-deep-{solid or ghost}: A variation with negative color scales for deeper background shades.

For standard interactive elements (<a>, <button>, <select>), and elements with [ui-interactive], applying color-*-solid and color-*-ghost applIes appropriate colors to interactive states such as [aria-pressed="true"], :hover, :active.

* ```css
*  background: var(--color-50);
*  color: var(--color-500);
* ```
*
* The number represents the approximate contrast against a white or black background.
* @reference Use `light-dark` to target both light and dark backgrounds at once: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Values/color_value/light-dark
* * `--color-*-100` is suitable as a background color.
* * `--color-*-400` has a contrast of approx. 3:1 over a background of 100, and is therefore usable for outlines and other essential non-text content according to WCAG2.
* * `--color-*-550+` has suitable contrast for high-visibility items such as small text.
* * If you use `--color-background-200` as a background color, then add 100 to all contrasting colors.
*
* On a dark background, higher numbers are brighter.

Responsive layouts

Use classes such as .layout-grid, .layout-row-reverse, .layout-stack etc. to create responsive layouts.

Tips

Add attributes such as align-start to elements with a layout class to align its items.
In nested flex layouts (row, stack), ui-shrinkable makes the child container shrink before the parent container does so.
Inside a grid, ui-span-all grows an item to full width.

All layouts in fw.css

/**
* Block sizes

* Discrete values on continuous scales. They combine nicely to form rhythms.
* Components expose them as string props:
* `<Button ui-block-size=24>`
*
* For vertical rhythm, all block sizes are fractions or multiples of 48 (the base rhythm). When using non-integer fractions such as 40 (5/6), add a gap of 1/6 to restore the rhythm.
*
* * Scales are unitless. Their name indicates the base CSS implementation but theme authors can apply nonlinear mappings.
* * To forbid page authors from setting a certain scalar, component authors can use `ui-block-size: never`.

## Block cadences and gaps

A cadence is the block-size (height) at which a pattern repeats. Example: Consecutive labeled single-line inputs in a form repeat each 96px. Use the gradient of gaps and cadences to create visual hierarchy and groupings. Equal cadences can harmonize a layout. Add spacers where sections are a little smaller than the next **multiple of 32px**.

Gaps and cadences are measured between **optical lines**. The optical line of text goes through the `-` glyph in the Lato font, which is 0.36em above the baseline. The optical lines of rectangular shapes are simply the edges. The optical lines of round and triangular shapes add some [_overshoot_](#overshoot), typically 8%, to balance out optical weight.

- **96**: Cadence of labeled inputs in a form
- **64**:
  - Gap between shapes or sections on a page
  - Gap between sections in a form
  - Total height (first to last line) of a single-line input
- **32**:
  - Distance between cards in a grid
  - Line height in large text and heading
  - Gap between items in a section
- **24**:
  - Line height in paragraph text
  - Bounding box height of a small circular or rectangular button or a pill ("Token")
- **16**: Line height in small text

  - Width of 1 column
  - Width of a square button
  - Bounding box width of a circular or square button
- **56**:
  - Cadence of circular or square buttons
- **80**: Cadence of single-column cards
- **96**: Content width in a small card or button
- **128**:
  - Width of a 2-column (small) card
  - Width of a standard button
- **160**:
  - Cadence of 2-column cards
  - Content width in a medium card
- **208**: Width of 3-column (medium) card
- **240**:
  - Cadence of 3-column cards

System utilities

Where possible, use Web defaults such as aria-pressed or disabled to cover semantics and looks in one go. In addition, the funkwhale design system offers a set of purely visual utilities, including custom properties ("Tokens") such as -- color-background-250, attributes such as ui-indicate-overflow and classes such as shape-circle.

These utilities are fully themeable.

See generated/fw.ts for the full list of the tokens, attributes and classes available.

Using system attributes

fw.css defines some attributes that can be reused across all components and HTML elements.

Example

Definition (fw.css -> generated/fw.ts)

uiBlockSize: '24' | '40' | '48' | '64' | '96'

Usage (Vue component or HTML file)

template

<Button ui-block-size="40">

Prefer using attributes such as ui-sunken over custom classes or styles where possible - this allows themes to change the look of the UI consistently and may prevent accessibility barriers or visual glitches when using custom themes.

System attributes are automatically exposed as typescript objects for smoother dx. More about typed design system attributes

Using system classes

Funkwhale classes are simple, composable utilities. Following the precedent set by the Tailwind team, we encourage you to always write out fill class names such as color-default-ghost layout-stack shape-circle.

Use the WithAttributes type utility to fine-tune the classes and attributes available on your custom component.

Design system architecture

Design decisions

See Architecture for an overview of the patterns we use to keep the codebase maintainable. Our long-term goal is to keep the design system and component library close to standard Html and WAI-Aria recommendations, and to leverage declarative patterns to make the Vue or HTML code as explicit and expressive as possible.

The fw theme is based on the original designs on https://design.funkwhale.audio. Palettes are extended into whites and blacks for versatility.
Fill types (solid, ghost) are part of the color name so that they appear together in the final class string.
The color definitions contain some redundancy - each color rule defines all default shades for all interactive states. Developers can fine-tune each individual shade, and we avoid overridden and indirect rules at the cost of repetition. Do use multibuffer editing for overarching refactors.
No borders. Only outlines (see the Interactivity section).
Repetition over abstraction - we avoid overriding rules and calculating intermediate variables such as --color-background-pressed and instead make the rules very granular and the custom properties non-inheriting where necessary.
