Hey! Well done on this package - fits my use case perfectly.

Just had one little bug come up that might help others - icons and text show up blurry when the marquee starts scrolling.

I was able to fix it with a line of CSS, might be useful to add a patch release eventually:

.js-marquee {
  backface-visibility: hidden;
}

Thank you @mattiacoll for releasing vanilla-marquee. I like the available options, here are the ones I use in my latest project:

const scroller = new marquee(el, {
	duplicated: true,
	speed: 80,
	startVisible: true,
});

When the children element dimensions change after the initialization of this library, it is possible to observe skips, overlaps and large empty areas.

Images that are lazy loaded result in their widths to be increased and this seems to break the animation. Firefox is especially prone to this, as it doesn't load anything below the fold (vs Chrome which is more lax and will try to load the images before they even come close to the viewport).

EDIT: The refresh method works great, I'll be closing this issue.

Doing import marquee from 'vanilla-marquee' fails in my project. Here is the stack trace:

node_modules\vanilla-marquee\dist\vanilla-marquee.js:704
