KNI SCSS

Our css starter pack and folder structure. The purpose of this repo is to have a single source of truth for all css used across, react, wordpress, static, or any future sites. When spinning up a new repo, please make sure it's using the latest version of this scss folder.

Install

This project runs on Node v18. Install Node 18 to run this project or install NVM and run nvm install v18. If using NVM, precede your npm run commands with nvm use.

Run npm i before running each NPM script to ensure that the project's dependencies are available and up to date.

Develop

To spin up the sass dev environment for this project, run npm run gulp. This will compile and watch ./test/test.scss and watch the ./scss directory for sass changes.

Code Formatting

This project uses prettier and stylelint for automatic code formatting and CSS linting. Prettier and stylelint can be run on the whole project at once by running npm run prettier and npm run stylelint. This project uses husky and lint-staged to automatically run prettier and stylelint on staged files to format files before they are committed. If any errors are thrown from either library during the pre-commit process, git will output the errors and the commit will be blocked until the errors are fixed.

Contributing

Contributions are welcome! Please either post an issue of a suggestion or open a pull request. Be sure to edit test/index.html to show clear example of code addition.

Responsive Theory

Will post more on our responsive theory soon, but for now:

• Write mobile-first css
• Use 2 "zones" vs many breakpoints
• Scale everything
• Use Fluid Typography

Mobile-first CSS:

Write all base styles then overwrite as necessary for desktop(landscape). This will result in much less overwriting of code. Mobile media queries should be rare.

body {
  padding: 0 5%;

  @media (min-width: #{$tp}px) {
    padding: 0 15pxv;
  }
}

2 Zones

Designs will have both portrait (mobile) designs and (desktop) designs delivered by the design team. In general these will be the sizes

• Mobile: 375px
• Desktop: 1440px

Scale Everything

We will be using the postcss-pxv plugin for viewport unit conversions.

input:

div {
  width: 150pxv;
}

output:

div {
  width: clamp(
    1px,
    calc(150vw * (100 / var(--siteBasis))),
    calc(150px * var(--siteMax) / var(--siteBasis))
  );
}

Fluid Typography

A fluid typography approach harnessing the power of css custom properties.

Example

.h-xxl {
  --fontSize: 38;

  @media (min-width: #{$tl}px) {
    --fontSize: 50;
  }
}

Example with clamp:

.body-m {
  --fontSize: 14;
  --fontSizeMinClamp: 12;

  @media (min-width: #{$tl}px) {
    --fontSize: 16;
    --fontSizeMinClamp: 14;
  }
}

Spacing

Included are some default spacing values for layouts. These can be overwritten on a project-basis, but we will mostly use these values on all projects.

$spacing-01: 6pxv;
$spacing-02: 12pxv;
$spacing-03: 16pxv;
$spacing-04: 34pxv;
$spacing-05: 32pxv;
$spacing-06: 40pxv;
$spacing-07: 48pxv;
$spacing-08: 64pxv;
$spacing-09: 80pxv;
$spacing-10: 96pxv;
$spacing-11: 120pxv;
$spacing-12: 160pxv;
$spacing-default: $spacing-07;
