Best JavaScript Background Animations to Check Out

Welcome! In this guide, we're going to be taking a look at some fantastic backgrounds that you can add to your site.

Animated backgrounds can be a great way to add a splash of color to any site, and help increase user engagement on-site too. I'd definitely recommend trying out some of the options shown below!

These backgrounds can be used for so many use cases, including login forms, signup screens, and hero banners. Or you could use them for landing page backgrounds too; if you'd like to create a great first-impression when a user lands on your site, animated backgrounds can be a great way to do so!

Let's get started!

Isotope UI

There are lots of sites that provide animated backgrounds, including sites that generate the code and markup required for the backgrounds.

The first site I'd recommend is Isotope UI, which has a fantastic selection of over 100 backgrounds, including many animated particle backgrounds! There are also lots of cool mesh gradient backgrounds available also, as well as backgrounds with SVG waves.

I've been using this background pack for a lot of my website projects and web apps, and I've found the particle animations to be incredibly useful for adding a beautiful backdrop to my web pages. Rather than creating custom particle animations from scratch, I find it much faster and easier to peruse the library and then choose the animation I'd like to add to my project!

Let's check out some of the particle backgrounds available!

Particles With a Gradient Background

One of the backgrounds available from the pack consists of the one shown below, featuring a glorious gradient background that moves from a blue tint to lovely purple color. An array of flickering particles create the animated effect.

You could use this for so many use cases, including login forms and signup screens.

You could try lots of cool and fun variations of this background, including updating the gradient and trying new colors too. For instance, you could update the colors to include coral pinks and bright purples!

Bubbles

The next background we're going to take a look at features cute bubbles that move from one side of the screen to the top of the screen. A lovely gradient contains subtle colors of pink and purple.

You could also add an SVG wave to this too, if you'd like to make the bubbles appear as if they are emerging from the waves.

SVG Waves With Particles

This stunning background has a series of flickering particles with a gradient backdrop, but it also has a cool SVG wave!

This background would look fantastic on landing pages, especially with the amazing SVG wave that acts as a page divider.

I've also seen variations which have animated SVG waves that move from one side of the screen to the other. To create new variations of this background, you could try combining different colors together, as well as adjusting the size or speed of the particles too.

Moving Squares

Another background available from the pack is this serene-looking backdrop, featuring rising squares and a lovely gradient.

The gradient contains hints and shades of blue and purple, and the squares are semi-opaque too, which leads to a cool effect overall.

This would look great for glassmorphic UIs or for the backdrop of a login screen or signup form too.

Constellations

This cool background would look amazing as the backdrop for signup screens as well as login forms, and so much more! There's also another configuration available with a different color palette to the one below too.

You could also create variations of this background by updating the color palette, such as by adding coral pinks, bright oranges and green colors for instance. There are lots of tools for generating color palettes, I'd definitely recommend generating various color palettes and then adding the colors to the particles.

These constellations would look great in loading screens or as the backdrop for a banner.

Particles.js Official Site

If you'd like some templates to help you get started, then be sure to take a look at the Particles.js official website! There are lots of cool templates to try out, and I've included some of the templates available in this article too, including a constellation animation and a festive snow effect.

You can also customize the backgrounds by updating the background color. Then when you have a background ready to go, simply export it and use the configuration on your site!

Snow

For a festive touch, why not add a snow animated background to your website? It could be a lovely way to add a festive animation during the winter months.

This background is available on the official Particles.js website, so be sure to take a look if you'd like to add this to your site! You can also edit the background color using the editing tool in the top-right corner, so be sure to try out different variations, too.

Constellation Effect

This background type is one of my favourites, featuring glorious line-linked particles, which create a cool constellation effect!

To create variations of this background, I would recommend updating the background color or trying out a cool gradient background too.

This background is available on the official Particles.js website! If you would like to use this library in your React project, I would recommend using TsParticles instead, as there's a pre-built component for adding particle effects to your React project.

Other Tools

Now that we've taken a look at two sources for animated particle effects, let's also take a look at some cool tools and generators for other animated backgrounds you could create!

Inixia

For example, Inixia has an animated gradient generator that you can use for your projects.

To get started, simply try out the different variations by clicking on the options in the left sidebar, and then click the "Export" button to get the HTML and CSS required. Then just pase this into your project and it's ready to go!

There are lots of options available on the left sidebar, as shown in the image below. For instance, there are lots of bright, fun gradient options, as well as those with lovely purple and blue tones too. Be sure to try out the various options, and see which works best for your site.

Granim.js

Granim.js is a library for creating animated gradients. I'd definitely recommend trying it out if you'd like to add a subtle animation to your site.

You can also check out lots of cool examples in the documentation too, so be sure to take a look at that if you're interested in discovering the various types of animations you can create with this library.

Be sure to try out different variations too, including different colors. For gradient inspiration or color inspiration, I've also written an article on the best CSS gradient generators. You could see which gradients look best for your project, and then include the colors in the Granim.js animation.
