Advanced tools
⚠️ Very early in development, more of a proof of concept than a real thing at the moment ⚠️
Add "CSS Components" support to Astro, inspired by eleventy-assets. This allows you to for instance, add page specific CSS. In my personal blog, I use it to add the CSS needed for syntax coloring only to the page that have code in them
The API is currently.. not very good. Use at your own caution - it should works, however

import BaseLayout from "BaseLayout.astro"
import { CSSComponent } from "astro-css-components"

<CSSComponent register={{ name: "should-be-red", content: ".should-be-red {color: red;}" }} />
<BaseLayout>
<article>
<div class="should-be-red">My super text</div>
</article>
</BaseLayout>

The CSSComponent component takes the following props:
Used to register a new component, it takes an object with the following attributes:
OR
Unless used with global, the component will be tied to the current URL
Examples:
<CSSComponent register={{ name: "should-be-red", content: ".should-be-red {color: red;}" }} />
<CSSComponent register={{ name: "code", contentFile: "src/theme/css/modules/code.css" }} />
By adding this props, you can make the component global, this mean you can call it from everywhere using getByName
Example:
<CSSComponent global register={{ name: "should-be-blue", content: ".should-be-blue {color: blue;}" }} />
By adding this props, you can only register the component when a certain condition is met
Example:
<CSSComponent register={{ name: "should-be-orange", content: ".should-be-orange {color: orange;}" }} conditional={page.loadCSSModules.includes("orange")} />
Get the components for the current URL, this get all the components registered for the current URL, to get a specific component, use getByName
Example:
<CSSComponent getForURL />
Get a specific component by name, this look in both the library for the current url and the global one
Example:
<CSSComponent getByName="should-be-yellow" />
