### Inline CSS
Use the `css` template tag for scoped inline styles in any page:
```tsx
import { css } from '@because/hype'
export default () => (
<section>
{css`
.hero {
background: linear-gradient(135deg, #667eea, #764ba2);
color: white;
padding: 4rem 2rem;
text-align: center;
}
`}
<div class="hero">
<h1>Welcome</h1>
</div>
</section>
)
```
This renders a `<style>` tag inline. Install the `vscode-styled-components` extension for syntax highlighting.

## The `fe()` Helper
`fe()` (short for "frontend") lets you define JavaScript functions on the server and use them as inline event handlers in SSR pages. The function bodies are automatically extracted and injected as a `<script>` before `</body>`.
### Basic usage
```tsx
import { fe } from '@because/hype'
const showAlert = fe(() => {
alert('ding dong')
})
export default () => (
<section>
<button onclick={showAlert}>Click me</button>
</section>
)
```
`fe()` returns a string like `"frontendFn0()"` which works as an `onclick` attribute value. The actual function is injected once in a `<script>` tag at the end of the page.
### Passing arguments
Pass server data to frontend functions:
```tsx
import { fe } from '@because/hype'
const greet = (name: string) => fe((args) => {
alert(`Hello, ${args.name}!`)
}, { name })
export default () => (
<section>
<button onclick={greet('Chris')}>Greet Chris</button>
<button onclick={greet('Alex')}>Greet Alex</button>
</section>
)
```
Arguments are JSON-serialized and passed at call time. The function body is deduplicated — if the same function is used with different arguments, only one copy of the function is injected.
### Deduplication
`fe()` deduplicates by function body. If you call `fe()` with the same function multiple times, it only injects one copy:
```tsx
import { fe } from '@because/hype'
const handleClick = fe(() => {
console.log('clicked!')
})
export default () => (
<section>
{/* Both buttons share the same injected function */}
<button onclick={handleClick}>Button 1</button>
<button onclick={handleClick}>Button 2</button>
</section>
)
```
---
## Inline `css` and `js` Tags
### `css` template tag
Returns a `<style>` element. Use it anywhere in your JSX:
```tsx
import { css } from '@because/hype'
export default () => (
<section>
{css`
.card {
border: 1px solid #ccc;
border-radius: 8px;
padding: 1rem;
}
`}
<div class="card">
<h2>Card Title</h2>
<p>Card content</p>
</div>
</section>
)
```
### `js` template tag
Returns a `<script>` element. The content is **transpiled from TypeScript** on the server using Bun's transpiler, so you can write TypeScript directly:
```tsx
import { js } from '@because/hype'
export default () => (
<section>
<div id="output"></div>
{js`
interface TimeData {
formatted: string
timestamp: number
}
function formatTime(ts: number): TimeData {
return {
formatted: new Date(ts).toLocaleTimeString(),
timestamp: ts
}
}
const el = document.getElementById('output')!
setInterval(() => {
el.textContent = formatTime(Date.now()).formatted
}, 1000)
`}
</section>
)
```
### Interpolation
Both tags support template literal interpolation:
```tsx
const primaryColor = '#3498db'
export default () => (
<section>
{css`
h1 { color: ${primaryColor}; }
`}
<h1>Styled heading</h1>
</section>
)
```
