This plugin enforces some of SMC’s best-practices for Liferay DXP themes.

Install the plugin:

yarn add @smclab/stylelint-dxp-theme

Configure it in your .stylelintrc:

{
  "plugins": [
    "@smclab/stylelint-dxp-theme"
  ],
  "rules": {
    "smc-dxp-theme/components": true,
    "smc-dxp-theme/disallow-ids": true
  }
}

The recommended theme structure (regarding CSS) is as follows:

src/css
│   # custom components:
├── components/_*.scss
│   # changes (and variants) to BS/Clay components:
├── styles/_*.scss
│   # import from ./styles and then ./components:
├── _aui_custom.scss
│   # customize BS/Clay:
└── _aui_variables.scss

rules: {
  "smc-dxp-theme/components": true
}

This rule is applied to all files inside src/css/components.

It requires all root selectors to be strictly related to the component styled in the file.

The name of the component comes from the name of the file.

my-cool-theme/src/css/components/_my-carousel.scss

// This rule is ok because it matches the file name:
+ .my-carousel {
+   background: white;
+ }

// Variants and components’ parts are ok too:
+ .my-carousel-vertical {
+   flex-direction: column;
+ }

// Unrelated selectors are not ok:
- .btn-for-carousel {
-    position: absolute;
- }

// Unrelated selectors are ok **if nested**
+ .my-carousel {
+   .btn-for-carousel { position: absolute; }
+ }

// All selectors in a list must be related, so this is not ok:
- .my-carousel, .my-pagination { … }

rules: {
  "smc-dxp-theme/components": true
}

This rule is applied to all files inside src/css/components and src/css/styles.

my-cool-theme/src/css/styles/_my-carousel.scss

// All selector types are ok…
+ a:link, a:visited { … }
+ [rel="slideshow"] { … }

// …but not IDs:
- #someid { … }
- .some-class #someid { … }
