Use custom marquee

[frm]

The marquee tag is sluggish on Firefox, especially on large screens.

We should instead add a custom marquee component that does the same effect. Preferably one that has an infinite closed loop, instead of leaving an empty space between elements like the native marquee tag allows.

@frm The marquee tag is deprecated. Perhaps that's why it doesn't work so well.

Yeah, they're not maintained, they're just kept for nostalgia. The day blink and marquee are removed, a little piece of the internet dies 😢

Either way, we're just suckers for these retro details on websites. Unfortunately, we'll have to add a custom element, the performance on Firefox is abysmal.
