Mechanical Ragger



npm i @oakstudios/mechanical-ragger

Web Component

  1. Load the web component. Choose the option that best suits your needs:

    Using a script tag placed at the end of the body:

    <!-- this automatically registers the component in the window as mechanical-ragger -->
    <script src="https://unpkg.com/@oakstudios/mechanical-ragger@0.4.1/web-component-auto-register.js"></script>

    OR importing the same auto-register function in JS:

    import "@oakstudios/mechanical-ragger/web-component-auto-register";

    OR registering the component manually:

    import MechanicalRagger from "@oakstudios/mechanical-ragger/web-component";
    customElements.define("mechanical-ragger", MechanicalRagger);
  2. Then add it to your HTML:

      Lorem ipsum dolor sit amet consectetur adipisicing elit.

React Component

import MechanicalRagger from "@oakstudios/mechanical-ragger/react";

export default () => {
  return <MechanicalRagger>Lorem ipsum dolor sit amet.</MechanicalRagger>;

Other Frameworks

While web components can be used in most any framework, if you'd like deep integration with the framework of your choosing, you can use src/web-component.js and src/react.jsx to reference in implementing mechanical-ragger elsewhere.

The npm package also exposes the MechanicalRaggerCore module that these use. eg:

import MechanicalRaggerCore from "@oakstudios/mechanical-ragger/core";



mechanical-ragger inherits the depth of the mechanical ragging from a CSS custom property. To set this to a value other than the default, apply the custom property anywhere in the DOM containing the mechanical-ragger.

/* Globally... */
body {
  --ragging-width: 3rem;

/* Or Locally */
mechanical-ragger:nth-child(1) {
  --ragging-width: 4rem;
mechanical-ragger:nth-child(2) {
  --ragging-width: 2rem;

Because this is a CSS custom property, you can change this value in the same place that you set the rest of your styles. The value will also respect other runtime conditions like media queries and application state.

mechanical-ragger {
  --ragging-width: 2rem;
/* Media Queries */
@media (min-width: 480px) {
  mechanical-ragger {
    --ragging-width: 3rem;
/* User Preferences */
body.no-ragging mechanical-ragger {
  --ragging-width: 0px;

You can also use any css unit (ch, em, rem, vw, etc)

Best Practices

ℹ️ Tidying line-ends

You may hope for text lines to reach closer to the end of each line to make the ragging cleaner. HTML and CSS both offer tools to manage this.


mechanical-ragger {
  /* Insert hyphens according to browser hyphenation dictionaries */
  hyphens: auto;

  /* Or only inserts hyphens at the author's request */
  hyphens: manual;

With hyphens: manual, use the &shy; HTML entity in your text to suggest hyphenation breakpoints to the browser.

In HTML, the <wbr> tag can be used to suggest a word breakpoint without hyphenation.

⚠️ Browser handling of line-heights.

Chrome and other browsers do not allow for floating-point decimal line-heights. All line-heights are rounded to the nearest CSS pixel (px values that do not factor in screen pixel-density). To ensure that the ragging does not fall out of sync with the text it controls, opt for line-heights that evaluate to whole pixels.



npm run build in the root directory. The resulting modules are generated from the src/ directory, to the root directory. This is the structure used in the npm package.


cd into the docs/ directory, where you can interact with the create-react-app instance.

cd docs

npm run start
