Loading

Plain HTML — CSS classes

The Tailwind v4 plugin. Works in any framework or none — Rails, Django, PHP, Go, a static file. This path is complete for Loading — it needs no JavaScript, so the classes below are the whole story.

/* in your CSS */
@import "tailwindcss";
@plugin "@wizeworks/silicaui";

Root class loading, with 5 modifiers:

• .loading
• .loading-lg
• .loading-md
• .loading-sm
• .loading-xl
• .loading-xs

React

Typed components over those same classes, with behavior and accessibility from Base UI.

npm i @wizeworks/silicaui-react

import { Loading } from "@wizeworks/silicaui-react";

Source of the demo above

The exact file that renders the examples above, so it can never drift from them. It imports a few of this site’s own layout helpers (../lib/…), so read it for the component calls rather than copying it whole.

import { Loading, Button } from "@wizeworks/silicaui-react";
import { Section, Row } from "../lib/Section";
import { SIZES } from "../lib/data";

export function LoadingDemo() {
    return (
        <>
            <Section title="Sizes">
                <Row>
                    {SIZES.map((size) => (
                        <Loading key={size} size={size} />
                    ))}
                </Row>
            </Section>

            <Section title="Real use · inline with text, and colored">
                <div className="flex flex-col gap-2 text-sm">
                    <span className="flex items-center gap-2">
                        <Loading size="sm" />
                        Loading your dashboard…
                    </span>
                    <span className="flex items-center gap-2 text-primary">
                        <Loading size="sm" />
                        Syncing changes…
                    </span>
                </div>
            </Section>

            <Section title="Button's built-in spinner (for comparison)">
                <Row>
                    <Button color="primary" loading>
                        Saving…
                    </Button>
                </Row>
            </Section>
        </>
    );
}

Vanilla — node tree to HTML

Feedback leaves — colorless status surfaces (class carries size/variant). Build a node tree, project it with toHtml(), and let the zero-dependency runtime hydrate it. This is the path for generated or user-authored documents — a site builder, CMS output, a static export.

npm i @wizeworks/silicaui-html @wizeworks/silicaui-behaviors

import { atom, toHtml } from "@wizeworks/silicaui-html";

const node = atom("Loading", "loading", { /* props */ });
const markup = toHtml(node);

Styling on this path is the class string in the second argument — the same classes as the Plain HTML section above. There is no color prop here; write "loading loading-primary" rather than passing a colour as a prop.
