## Why Forge?
## overview
CSS is powerful, but hostile.
Forge is a typed, local, variant-driven way to organize CSS and create
self-contained TSX components out of discrete parts.
### Problems with CSS
## css problems
- Styles are **global and open** — anything can override anything.
- Theres **no link** between a class in markup and its definition.
- Inline styles exist because theres **no structured way to vary styles per instance**.
- Overrides are silent — conflicts happen without feedback.
- Complex components require selector gymnastics and reach-in styling.
- Styles are global and open - anything can override anything anywhere.
- No IDE-friendly link between the class name in markup and its definition.
- All techniques are patterns a human must know and follow, not APIs.
- Errors happen silently.
### What Forge Does Instead
## forge solutions
- Styles are **local to components** and attached by generated handles, not strings.
- **Parts** give components named sub-targets without selectors.
- **Variants** replace inline styles with typed, declarative parameters.
- Style composition is **deterministic** (known merge order, last-wins).
- Overlapping changes are **warned about in dev**, not silently ignored.
- All styles are local to your TSX components.
- Styles defined using TS typing.
- Component styles are made up of independently styled "Parts".
- "Variants" replace inline styles with typed, declarative parameters.
- Style composition is deterministic.
- Themes are easy.
- Errors and feedback are provided.
### What Forge Is
## examples
- A typed, local, variant-driven way to author CSS.
- A system that optimizes for **people typing at a keyboard**, not selectors in a cascade.
### styles
### What Forge Is Not
```tsx
import { define } from "forge"
- Not a new component model.
- Not a new language.
- Not a CSS replacement — it compiles _to_ CSS, but removes the chaos.
export const Button = define("button", {
base: "button",
padding: 20,
background: "blue",
})
// Usage
<Button>Click me</Button>
```
### variants
Example:
```tsx
import { define } from "forge"

import { Profile } from './whatever'
console.log(<Profile pic={user.pic} bio={user.bio} />)
console.log(<Profile size="small" pic={user.pic} bio={user.bio} />)
```
### selectors
Use `selectors` to write custom CSS selectors. Reference the current
element with `&` and other parts with `@PartName`:
```tsx
const Checkbox = define("Checkbox", {
parts: {
Input: {
base: "input[type=checkbox]",
display: "none",
},
Label: {
base: "label",
padding: 10,
cursor: "pointer",
color: "gray",
selectors: {
// style Label when Input is checked
"@Input:checked + &": {
color: "green",
fontWeight: "bold",
},
// style Label when Input is disabled
"@Input:disabled + &": {
opacity: 0.5,
cursor: "not-allowed",
},
},
},
},
render({ props, parts: { Root, Input, Label } }) {
return (
<Root>
<Label>
<Input checked={props.checked} />
{props.label}
</Label>
</Root>
)
},
})
// Usage
<Checkbox label="Agree to terms" checked />
```
## themes
built-in support for CSS variables with full type safety:
```tsx
// themes.tsx - Define your themes
import { createThemes } from "forge"
export const theme = createThemes({
dark: {
bgColor: "#0a0a0a",
fgColor: "#00ff00",
sm: 12,
lg: 24,
},
light: {
bgColor: "#f5f5f0",
fgColor: "#0a0a0a",
sm: 12,
lg: 24,
},
})
// Use theme() in your components
import { define } from "forge"
import { theme } from "./themes"
const Button = define("Button", {
padding: theme("spacing-sm"),
background: theme("colors-bg"),
color: theme("colors-fg"),
})
```
Theme switching is done via the `data-theme` attribute:
```tsx
// Toggle between themes
document.body.setAttribute("data-theme", "dark")
document.body.setAttribute("data-theme", "light")
```
The `theme()` function is fully typed based on your theme keys, giving
you autocomplete and type checking throughout your codebase.
## scopes
Sometimes you want your parts named things like ButtonRow, ButtonCell,
ButtonTable, etc, but all those Button's are repetitive:
```typescript
const { define } = createScope("Button")
// css class becomes "Button"
const Button = define("Root", {
// becomes "Button"
// ...
})
// css class becomes "ButtonRow"
const ButtonRow = define("Row", {
// ...
})
// css class becomes "ButtonContainer"
const ButtonContainer = define("Container", {
// ...
})
```
