ui_styles

Allows developers to define styles from modules and themes and site builders to use them from Drupal admin interface.

The styles are:

• collections of mutually exclusive, self-descriptive, single-purpose CSS classes. Examples: Typography, Borders, Background colors, Spacing....
• commonly used in design systems, and can also be called "helpers", "utilities", "fundamentals"...
• Drupal plugins, created and managed by the themer, inside a single YML file.

Examples of styles in upstream design systems:

• Bootstrap’s utilities: https://getbootstrap.com/docs/5.3/utilities/api/
• Tailwind in DaisyUI: https://daisyui.com/docs/utilities/
• Material’s styles: https://m3.material.io/styles
• Bulma’s helpers: https://bulma.io/documentation/helpers
• PatternFly’s utility classes : https://www.patternfly.org/utility-classes/about-utility-classes
• USWDS’s utilities: https://designsystem.digital.gov/utilities/

Styleguide

A styles library page is generated as documentation for content editors or as a showcase for business and clients:

Site building features

Once created, the styles can be used with:

Block, on block titles, block content and block wrappers.
Themes regions. Note that if you have a region's Twig template not using the attributes variable it will not work.
Layout Builder, on block titles, block content, block wrappers, sections and sections' regions. It works also with layout builder overrides (custom layout for a content entity).
Views, on view wrappers ("view styles"), exposed forms and pagers.
Ckeditor5, as inline class and as block class.
Entity Status, on unpublished entities.
Paragraphs. Available styles are setup for each paragraph type.

It is also possible to add free extra classes, using a simple text field.

Each integration is a module to activate:
