Svelte Body
Works with Svelte 3 & 4!
Apply styles to the body in routes! Designed to work with Svelte Kit and Routify.
Example REPL
Why?
Currently in Svelte Kit and Routify, applying styles per page to the body doesn't work. You can't use :global(body) since the style tags aren't removed and reapplied on route change. svelte-body handles that for you!
Install
npm i svelte-body -D
# pnpm
pnpm add svelte-body -D
# yarn
yarn add svelte-body -DUsage
Just like in regular html you can apply classes with class="" and styles with style="".
<script>
import { Body } from 'svelte-body';
</script>
<Body class="some classes" style="color: blue" />Alternativley you can use a style object like so:
<script>
import { Body } from 'svelte-body';
const style = {
backgroundColor: 'violet',
color: 'white',
'--cool-css-prop': '😎'
};
</script>
<Body {style} />For Class, you can pass a combination of string, object, and array of both of these. Literally anything that can be passed to class.
<script>
import { classList } from 'svelte-body';
let isBlue = true;
</script>
<Body class="red green blue" />
<Body class={{ red: true, blue: isBlue }} />
<Body class={['red', isBlue && 'blue']} />
<Body class={[ 'red', { blue: isBlue } ]} />Actions
There are also svelte actions that can be used on <svelte:body />:
-
classList<script> import { classList } from 'svelte-body'; </script> <svelte:body use:classList={"red green blue"} /> <svelte:body use:classList={{ red: true, blue: isBlue }} /> <svelte:body use:classList={['red', isBlue && 'blue']} /> <svelte:body use:classList={[ 'red', { blue: isBlue } ]} />
-
style<script> import { style } from 'svelte-body'; </script> <svelte:body use:style={"background-color: blue;"} />
It can also take an object:
<script> import { style } from 'svelte-body'; </script> <svelte:body use:style="{{ backgroundColor: 'blue', '--cool-css-prop': '😎' }}" />
