Display a BlurHash using only CSS thanks to blurhash-to-css

If you want to display Blurhash Placeholder Images on your site you need a JavaScript solution to do so. The blurhash-to-css package bypasses that, as it allows you to convert a Blurhash to a set of CSS properties that need to apply.

import { blurhashToCss } from "blurhash-to-css";

const css = blurhashToCss(
  "eCF6B#-:0JInxr?@s;nmIoWUIko1%NocRk.8xbIUaxR*^+s;RiWAWU"
);
