Self-closing HTML tags for non-void elements are ambiguous — use `<%name% ...></%name%>` rather than `<%name% ... />`
```
In HTML, there's [no such thing as a self-closing tag](https://jakearchibald.com/2023/against-self-closing-tags-in-html/). While this _looks_ like a self-contained element with some text next to it...
```html
<div>
<span class="icon" /> some text!
</div>
```
...a spec-compliant HTML parser (such as a browser) will in fact parse it like this, with the text _inside_ the icon:
```html
<div>
<span class="icon"> some text! </span>
</div>
```
Some templating languages (including Svelte) will 'fix' HTML by turning `<span />` into `<span></span>`. Others adhere to the spec. Both result in ambiguity and confusion when copy-pasting code between different contexts, and as such Svelte prompts you to resolve the ambiguity directly by having an explicit closing tag.
To automate this, run the dedicated migration:
```bash
npx sv migrate self-closing-tags
```
In a future version of Svelte, self-closing tags may be upgraded from a warning to an error.

In runes mode, `<MyComponent>` will re-render if the value of `MyComponent` changes.
In runes mode, `<MyComponent>` will re-render if the value of `MyComponent` changes. See the [Svelte 5 migration guide](/docs/svelte/v5-migration-guide#Breaking-changes-in-runes-mode-svelte:component-is-no-longer-necessary) for an example.
In legacy mode, it won't — we must use `<svelte:component>`, which destroys and recreates the component instance when the value of its `this` expression changes:
