styles: CSSResult[]

Array of styles to apply to the element. The styles should be defined using the ? tag function, via constructible stylesheets, or imported from native CSS module scripts.

Note on Content Security Policy:

Element styles are implemented with <style> tags when the browser doesn’t support adopted StyleSheets. To use such <style> tags with the style-src CSP directive, the style-src value must either include ‘unsafe-inline’ or nonce-<base64-value> with <base64-value> replaced be a server-generated nonce.

To provide a nonce to use on generated <style> elements, set window.litNonce to a server-generated nonce in your page’s HTML, before loading application code:

<script>
  // Generated and unique per request:
  window.litNonce = 'a1b2c3d4';
</script>
