// Build Svelte components. Use for Svelte custom elements, component libraries (Bits UI, Ark UI, Melt UI), form patterns, or third-party integration.
Svelte 5 core best practices. Use when creating, editing, or reviewing .svelte, .svelte.ts, or .svelte.js files. Routes to deeper Svelte skills.
Build Svelte LayerChart components. Use for tooltip snippets, Chart context access, gradients, highlights, axes, and Svelte 5 snippet patterns.

Form trick: Use form attribute when form can't wrap inputs:
<form id="my-form" action="/submit"><!-- outside table --></form>
<table>
<tr>
<td><input form="my-form" name="email" /></td>
<td><button form="my-form">Submit</button></td>
</tr>
</table>
// svelte.config.js
export default {
compilerOptions: {
customElement: true,
},
};
<!-- MyButton.svelte -->
<svelte:options customElement="my-button" />
<!-- Native <slot> is appropriate inside custom elements. -->
<button><slot /></button>
defaultValue attribute enables easy form resets{@render} for normal Svelte component content; native <slot> is for custom elements
