Component Naming Convention

When designing Inkline, component names and prop names were chosen to be as intuitive as possible. The naming rules are:

  • Namespacing - Component names should be namespaced using the I prefix to be easily recognizable and to avoid conflicts.
  • Simplicity - Component names should be simple words where possible in order for them to be easy to remember: IContainer, IButton, INavbar, etc.
  • Clarity - Component names should clearly reflect parent-child component relationships: INav and INavItem.
  • Consistency - Component prop names should be reused as often as possible to promote consistency: color, size, disabled, etc.

CSS Naming Convention

Inkline uses RSCSS (Reasonable System for CSS Stylesheet Structure) principles as a base for naming classes, making them much easier to read and write. RSCSS is a simplified, more readable version of BEM.

The RSCSS naming convention encourages you to think in components and revolves around three core concepts: components, variants and utilities.

<div class="container -fluid _text:center">
  • .container represents a component class
  • .-fluid represents a variant class, specific to the component
  • ._text:center represents a utility class

Components are standalone entities that are meaningful on their own. Each component should be aware of its own design only, and should be usable without a specific context unless it's the only context they should be used in.

.navbar { /* ... */ }

.container { /* ... */ }

.button { /* ... */ }

Components may have variants that modify their appearance or behaviour. Class names for variants will be prefixed by a dash (-).

.button {
    &.-primary { /* ... */ }
    &.-disabled { /* ... */ }
    &.-block { /* ... */ }

Utility classes are general-purpose helper classes meant to override values. Class names for helpers will be prefixed by an underscore (_). When adding the ! suffix, helpers provide styles that are tagged with !important.

._margin:0 { margin: 0; }

._text:center { text-align: center; }

._display:flex! { display: flex !important; }
Design Tokens

CSS Variables in Inkline have a consistent naming scheme that you can follow whenever you want to redesign a component.

  • Global Design Tokens use only single hyphens -, can be either standalone or composed, and are very intuitively named:
var(--padding); // var(--padding-top) var(--padding-right) var(--padding-bottom) var(--padding-left)
var(--color-primary) // var(--color-primary-h) var(--color-primary-s) var(--color-primary-l) var(--color-primary-a)
  • Component Design Tokens use the following naming convention:
