Line fireworks animation

Rockets streak up and burst into bold line fireworks in your colours, on a clear background.

Edit this in Mosso

Change anything, then export a GIF, an MP4 or a transparent video.

Try a look

Shown in a sample look. In Mosso it switches to your brand in one click.

Smooth motion. Confident and clear. Smooth moves with a gentle landing.

We read the colours and fonts from your home page. They stay in this browser.

The sample look, font and background are shared.

Free download

Free for your own projects and client work, including commercial use. Read the licence

What it's good for

It is 1080 × 1080 pixels and 4 seconds long, and it is set to loop. Check the loop and contrast after editing. The background is transparent, so it sits on top of any page, photo or video.

The colours come from your brand kit. Change the timing in the editor.

  • The moment someone finishes a signup, order or upgrade
  • Launch, birthday and New Year posts
  • Win screens in apps and games
  • New Year posts and countdowns
  • Birthday and party invitations

How to use it on a website

  1. Pick your brand above, then download the dotLottie file.
  2. Add it to your site's files, for example as /animations/fireworks-burst.lottie.
  3. Paste the code where the animation should play.

Without code

  • Webflow: upload the Lottie JSON file in the Assets panel, then drag it onto your page.
  • Framer: add a Lottie component and give it the JSON file.
  • WordPress: use a Lottie block plugin and upload the JSON file.

Need it as a GIF or a video? Download the Lottie JSON and use the free Lottie to GIF or Lottie to MP4 converter, or check any file in the Lottie viewer.

For the steps in Mosso, read Edit a template.

Use it in code

Download the file, then copy the code for your platform. It loops, and it holds a still frame for people who ask for less motion.

  1. Put fireworks-burst.lottie in your site's animations folder, so it loads from /animations/fireworks-burst.lottie.
  2. Paste this where it should play.
index.html
<script type="module" src="https://cdn.jsdelivr.net/npm/@lottiefiles/dotlottie-wc@0.10.0/dist/dotlottie-wc.js"></script>

<dotlottie-wc src="/animations/fireworks-burst.lottie" autoplay loop data-still="0.704"
  aria-hidden="true"
  style="display: block; width: 100%; aspect-ratio: 1 / 1; pointer-events: none"></dotlottie-wc>

<script>
  // People who ask for less motion see a still frame: data-still is how far in, from 0 to 1.
  if (matchMedia('(prefers-reduced-motion: reduce)').matches) {
    const players = document.querySelectorAll('dotlottie-wc');
    players.forEach((el) => el.removeAttribute('autoplay'));
    customElements.whenDefined('dotlottie-wc').then(() => players.forEach((el) => {
      const player = el.dotLottie;
      if (!player || !el.dataset.still) return;
      const show = () => player.setFrame(Math.round(Number(el.dataset.still) * (player.totalFrames - 1)));
      if (player.isLoaded) show();
      else player.addEventListener('load', show);
    }));
  }
</script>

Lottie in HTML: setup and common problems

Good to know

  • Let clicks pass through

    When confetti plays over your page, give it pointer-events: none so people can still click whatever is underneath.

  • Play it once

    Celebrations work best right after the action, played once. Confetti that never stops turns into noise.

  • Use dotLottie for confetti

    Confetti has lots of small pieces, so its files are bigger than an icon's. The zipped dotLottie file is much smaller than the JSON.

  • Respect reduced motion

    Some people ask their device for less motion. Check prefers-reduced-motion and show a still frame for them instead.

Questions

Is this line fireworks animation free?

Yes. A free account lets you download up to 50 library animations a day. You may edit these animations and use them in personal and commercial work, including client projects. Third party parts keep their own licences. Keep the supplied notices and credits when you share them. Mosso does not require a credit for its own work. The restriction on reselling Mosso templates does not limit rights granted by third party licences.

Can I change the colours?

Yes. Pick a sample look above to see how it changes. Open the Mosso project to edit its layers, timing and effect settings, and add your logo. Imported files may have fewer editable parts.

Should I download Lottie JSON or dotLottie?

dotLottie is the same animation in a zipped file, so it is smaller: this one is about 6.4 KB instead of 73 KB. Use it with the dotLottie players for the web, React, iOS and Android. Pick Lottie JSON when a tool asks for a .json file, like Webflow or lottie-web.

Can I get it as a GIF or a video?

Yes. Open it in Mosso and export a GIF, an MP4, a WebM video with a transparent background or PNG frames, all from the same project.

Is the background transparent?

Confetti is. Where an animation comes with a background, like the night sky behind fireworks, you can switch it off with the Background switch before you download.
