npm (scoped) Travis (.com) master build

Sass library optimized for AMP, size: 44KB (gzip 8KB) - or only 27KB without responsive spacings!

Features a low-level OOCSS framework with optional CSS output and ready components to speed up development and page load!

CSS semantics like bootstrap or Basscss (e.g. col-md-6 or md-col-6). Used CSS selectors can be changed for (currently just) some components, like applying button styles only to .btn and not on .btn, button, input[type='button'], input[type='reset'], input[type='submit'] or using .button/.button-round/.button-lg instead of .btn/.btn-round/.btn-lg.

From Version >0.20.0 onwards this library is inspired and based upon mustard-ui and Basscss. But written in Sass, with more configuration options through Sass variables, which where not existing in mustard or done by CSS vars in Basscss. Sass mixins are included for easier reuse without copying Sass/CSS.

Take a look & inspect the example page for all selectors and styles. For implementation details check the documentation of Sass and CSS.

Quick Start

Install package: npm i --save-dev @formanta/sass

Add imports, config and custom styles in your .scss/.sass file:

// `@import` may differ depending on your setup

// overwrite default variables here

// get mixins, functions, variables from Formanta
@import "node_modules/@formanta/sass/meta";

// own styles which may use Formanta Sass
.bg-grey {
    background: $color-gray-600;
    margin: space(1);

// get everything that actually produces CSS from Formanta
// or get the imports from the file and load only what is needed
@import "node_modules/@formanta/sass/style";

// maybe, maybe overwrite Formanta styles here
// add styles which rely on component variables (e.g. `$panel-shadow`) (todo: change all vars to `meta`)

Reference the transpiled CSS file and use the CSS classes and styles in your next awesome project!

Small boilerplate to get you started, also on codesandbox, for a more real life example check the example page.
