Marquee

tag is the wrapper element. Swap it for a landmark when the strip is a real region of the page rather than decoration.

orientation scrolls the strip horizontally or vertically. Vertical needs a height on the marquee: there's nothing else to bound the loop.

reverse runs the loop the other way. It's most useful on a second marquee stacked under the first — two strips moving in opposite directions read as motion rather than as a single drift.

pauseOnHover stops the loop while the pointer is over the strip. Worth setting whenever the content is something you'd want to read or click, which is most content that isn't purely decorative.

repeat sets how many times the slot content repeats to fill the loop. Raise it when the content is short enough to leave a gap.

overlay is the edge fade. On by default so items enter and leave rather than being clipped; turn it off when the marquee sits on a surface the fade can't match.

Whatever you put in it is what repeats — tags here, but logos, quotes or avatars work the same way.
