add x button

click on it will remove the top bar.

top bar will re appear on reloading the page.

top bar will re appear on reloading the page.

That makes the button less useful IMO. Maybe something like this:

const onClick = () => localStorage.setItem('hellobar', content)
const onLoad = () => { if (localStorage.getItem('hellobar') === content) return }

In that case it should be a cookie so it don't FOUC on SSR.
