Installation

npm install @groww-tech/mint-css

Usage

First, import the package in the root document of your project.

import '@groww-tech/mint-css/dist/index.css';

The dist/index.css is complied and minfied version of the CSS library which will serve all the tokens/classes which can be used in your project.

Fragments

If you prefer not to import all classes at once by using 'dist/index.css' or want to use specific parts of mint-css, you can leverage fragments. Fragments allow you to import only the styles you need, keeping your bundle size smaller and more focused.

• Optimized Imports: Only include the CSS you need, reducing unused styles.
• Flexibility: Customize your usage by combining specific fragments as required.
• Scalability: Easily add or remove fragments as your project evolves.

Variables

Includes all design tokens, such as colors, spacing, and typography variables.

import '@groww-tech/mint-css/dist/fragments/allVariables.css';

Font Faces

Contains font-face declarations for the typography used in the design system. ex: GrowwSans

import '@groww-tech/mint-css/dist/fragments/fonts.css';

Theme Utilities

Provides utility classes for themes and other theming-related styles.

import '@groww-tech/mint-css/dist/fragments/themeUtilities.css';

Typography Utilities

Includes utility classes for typography, such as body, display, button typography.

import '@groww-tech/mint-css/dist/fragments/typographyUtilities.css';

Features

What are Tokens?

Tokens are abstract entity which denotes symantic meaning and store values. When you use contentAccent, you’re using a colour token which contains #00B386 as its value, same is applicable to typography.

There are two categories through which we will be exposing various semantic tokens. The tokens are further categorized based on visual emphasis and hierarchy of the UI elements.

1. Typography tokens

   GrowwSans and NotoSans font families will get downloaded once you install and import the library into your project. These are the tokens can be used -

   • Body
   • Display
   • Heading
   • Button

   e.g. The token bodySmall says that, it can be used in body with regular font weight which have font size of 12pts.

   .bodySmall {
       font-size: var(--font-size-12);
       font-weight: var(--font-weight-regular);
       line-height: 1.5;
   }
   

   <div className="bodySmall">Some content</div>

   ---

2. Color tokens

   Again, the color tokens are further classified into different categories and can be used in different styles depending on the UI elements

   • Background
   • Content
   • Border

   e.g. We have a token called contentPrimary which refers to the most important and essential information within a piece of content.

   .contentPrimary {
     color: var(--content-primary);
   }
   

   <div className="contentPrimary">Some content</div>
