Fundamental Library Styles

What is Fundamental Library Styles?

Fundamental Library Styles is a light-weight presentation layer that can be used with your UI framework of choice (e.g. Angular, React, Vue, etc.). With Fundamental Library Styles’ library of stylesheets and HTML tags, developers can build consistent Fiori apps in any web-based technology.

We are also working on Angular, React and Vue implementations.

Getting Started

The library is modular so you can use as little or as much as you need.

CDN

The fully compiled, minified library is available via CDN for inclusion in your application.

NPM Package

The compiled CSS for the full library and modules, e.g., core, layout, etc., are distributed via NPM.

npm install fundamental-styles --save

NOTE: We only distribute the fonts, icons and compiled CSS for each component, not the full project or HTML for specific components.

Few differences between Fundamental Library Styles and Fundamental

Fundamental Library Styles is aiming to deliver:

• Fiori 3.0 compliant components
• themable components built on top of SAP Theming Base Content by consuming the CSS Custom Properties delivered by the theming library
• self-contained components(each component style file contains all the styling needed to be rendered properly and at the same time avoid external styling bleeding in and bleading out. Bleading in means that global reset wouldn't affect the component and bleading out means that the component styling should not affect other HTML elements)
• An html reference specification that consuming libraries must adhere to.
• Accessibility support
  • Accessibility - Color contrast support for WCAG 2.0 level AA (4.5:1 for typical text)
  • Accessibility - Semantic HTML reference
  • Accessibility - Aria attributes noted when possible in HTML reference

This library is also being consumed by Fundamental Library for Angular, Fundamental Library for React, and Fundamental Library for Vue.

Versioning

The fundamental-styles library follows Semantic Versioning. These components strictly adhere to the [MAJOR].[MINOR].[PATCH] numbering system (also known as [BREAKING].[FEATURE].[FIX]).

Merges to the master branch will be published as a prerelease. Prereleases will include an rc version (e.g. [MAJOR].[MINOR].[PATCH]-rc.[RC]).

The following circumstances will be considered a MAJOR or BREAKING change:

• Droppping existing classnames, css variables, color names, color groups, spacing parameters
• The existing underlying HTML markup of a component is altered
• An existing unit test is altered to account for either of the above

The following circumstances will NOT be considered a MAJOR or BREAKING change:

• Introducing new classnames, css variables, color names, color groups, spacing parameters
• Non-visual HTML attribute changes/additions (such as role, aria-*, data-*)
• Adding or modifying CSS properties and values of existing classnames.
• An existing unit test is altered to account for non-visual HTML attribute changes/additions (such as role, aria-*, data-*)
