@hi_mayank Like regular JavaScript components/fragments in Kitten (.component.js/.fragment.js files), HTML and CSS fragments actually get converted to JavaScript modules.
So, for example, my.fragment.html:
```html
<div>
<h2>Slot ahead</h2>
${SLOT}
</div>
```
Would get converted into:
```js
export default ({SLOT = ''}) => kitten.html`
<div>
<h2>Slot ahead</h2>
${SLOT}
</div>
`
```
Hope that helps clarify the reasoning. I’m trying not to introduce extra syntax whenever possible :)
