### `feather.replaceElement(element, [attrs])`
Replace a element that have a `data-feather` attribute with SVG markup corresponding to the element's `data-feather` attribute value.
#### Parameters
| Name | Type | Description |
| ---------- | ------ | ----------- |
| `element` | HTMLElement | The element to be replaced, required a `data-feather` attribute |
| `attrs` (optional) | Object | Key-value pairs in the `attrs` object will be mapped to HTML attributes on the `<svg>` tag (e.g. `{ foo: 'bar' }` maps to `foo="bar"`). All default attributes on the `<svg>` tag can be overridden with the `attrs` object. |
#### Usage
> **Note:** `feather.replaceElement()` only works in a browser environment.
Simple usage:
```html
<i data-feather="circle"></i>
<!--
<i> will be replaced with:
<svg class="feather feather-circle" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>
-->
<script>
const element = document.querySelector('i')
feather.replaceElement(element)
</script>
```
You can pass `feather.replaceElement()` an `attrs` object:
```html
<i data-feather="circle"></i>
<!--
<i> will be replaced with:
<svg class="feather feather-circle foo bar" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>
-->
<script>
const element = document.querySelector('i')
feather.replaceElement(element, { class: 'foo bar', 'stroke-width': 1 })
</script>
```
All attributes on the placeholder element (i.e. `<i>`) will be copied to the `<svg>` tag:
```html
<i data-feather="circle" id="my-circle" class="foo bar" stroke-width="1"></i>
<!--
<i> will be replaced with:
<svg id="my-circle" class="feather feather-circle foo bar" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"></circle></svg>
-->
<script>
const element = document.querySelector('i')
feather.replaceElement(element)
</script>
```
