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 v16. Install Node 16 to run this project or install NVM and run nvm install v16. 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 sass-dev. This will compile and watch ./test/test.scss for 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 15vw;
  }
}

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: 1280px (Sometimes 1440px)

Scale Everything

We're introducing a new vw() function which takes these sizes into account.

Input:

div {
  width: vw(320px);
}

Output:

div {
  width: 2.34375vw;
}

The output becomes a flexible vw unit that changes as browser resizes. At 1280px it should match up exactly to the comp.

Use the pixel sizes you see in Figma and wrap them in this function everywhere. The exception is if you want to use actual pixels, then use px or rem(px) and it will output fixed pixel sizes.

Fluid Typography

We have 2 mixins to help with Fluid Typography.

fluidType()

Base mixin:

.item {
  @include fluidType($minFontSize, $maxFontSize, $minWidth, $maxWidth);
}

setType()

This is superset of fluidType that should be used in most cases, and is great for Figma matching. Use this for fully responsive type automation. In most cases you only need to provide 2 arguments: The mobile size and the desktop size. Note these values are not the same as fluidType.

h1 {
  @include setType(32, 48);
}

Sometimes for smaller fonts you want to override the smallest size that it can go. In this case pass in the $minClamp argument which is the percentage the minimum font size should be compared to default size. Set it to 100% to have it not scale any smaller than default size.

p {
  @include setType(14, 16, $minClamp: 94%);
}
.eyebrow {
  @include setType(11, 13, 100%);
}
