Sparticlesjavascript particles in canvas High Performance Particles in Canvas.For those occasions when you 👏 just 👏 gotta 👏 have 👏 sparkles,snow, or stars on your homepage!installationparametersoptionsmethodsstylingperformancewhy?installationDepending on how your project looks,you may want to include a direct link to the script andthen initialise the sparkles,or you may wantto import the module in to your application for a more modern approach.vanillafirstly make sure you've downloaded the latest version of the scriptto your application directory (if you are running on a CMS you might alsoneed to upload the file to your server). The file you'll want to use is; dist/sparticles.min.jsto make sure it downloads the fastest for your users.After you've downloaded, or uploaded, the sparticles.min.js file to thecorrect place, you'll then need to include it in your web page;">script src="../path/to/sparticles.min.js">script>And finally, you should then be able to initialise the Sparticles byrunning this code in your javascript;(make sure this code runs after you've included the script above.) window.onload = function() { let myElement = document.getElementById("myDiv"); let mySparticles = new Sparticles(myElement, { count: 100 }, 400); }">script> window.onload = function() { let myElement = document.getElementById("myDiv"); let mySparticles = new Sparticles(myElement, { count: 100 }, 400); }script>jqueryFor jQuery sites, you may follow all of the steps above, but replacethe third step with something like below; let $el = $("#myDiv"); let mySparticles = new Sparticles($el[0], { count: 100 }, 400);">script> let $el = $("#myDiv"); let mySparticles = new Sparticles($el[0], { count: 100 }, 400);script>app / bundlerIf you're running a more modern type of application with something like Svelte or VueJs;First you will want to install the module with NPM;yarn add --dev sparticles# or npm, if you prefernpm install --save-dev sparticlesThen import the module in to the app where you want to use itimport Sparticles from "sparticles";Finally initialise with vanillaJSnew Sparticles(node, { count: 100 }, 400);If you're using SvelteJS specifically, then your single-file componentwould look a little like this; import Sparticles from "sparticles"; let sparticles, options = { color: "gold", shape: "star", speed: 50 }; function addSparticles(node) { new Sparticles(node, options, 400); }">script> import Sparticles from "sparticles"; let sparticles, options = { color: "gold", shape: "star", speed: 50 }; function addSparticles(node) { new Sparticles(node, options, 400); }script>main use:addSparticles>main>usageProviding that the script/module has been properly included, then it can be initialisedby running the Sparticles() constructor;let mySparticles = new Sparticles();parametersWhen initialising the Sparticles instance there are some parameters that can be supplied.parametertypedefaultdescriptionnodeHTMLElementdocument.bodythe element in the DOM which the Sparticles will append tooptionsObject{}an object with all the options for the instancewidthNumbernode.clientWidththe width of the canvas elementheightNumbernode.clientWidththe height of the canvas element (defaults to width)Leave the width/height properties empty to make the canvas resize to fit it's nodeSupply nothing and get a default Sparticle instance on the let mySparticles = new

Additionally "random" can be used to assign any random color.randomColorType: FunctionDefault: randomHSL()Arguments: index, totalCustom function to use when generating random colors. The default function will return a fairlypleasant hsl() color with a high saturation and medium lightness. This can be overridden to suityour environment better.

Sense. Other, higher-pitched vibration modes should produce related but substantially more massive families of particles, dubbed superparticles, or sparticles. String theory predicts that all subatomic particles have such partners. For example, the electron should have a superpartner dubbed the selectron, while each quark has a superpartner called a squark. No one has yet detected a sparticle, perhaps because existing particle accelerators are too feeble.Some physicists expect the Large Hadron Collider to be powerful enough to reveal sparticles. The heart of the collider is a 17-mile-long circular tunnel straddling the border of France and Switzerland. There, two beams of protons will circulate in opposite directions. When engineers flip a switch in 2007, a 12,000-ampere pulse of electrical power will slam down huge coils of electromagnets, creating fields 100,000 times more powerful than Earth’s. The magnets will bend particles along a circular path as they accelerate to 99.999999 percent the speed of light and attain energies approaching 14 trillion electron volts, trillions of times more powerful than the energy released by dynamite.Before the Large Hadron Collider goes hunting for sparticles, it will first test the boundaries of the standard model of particle physics, the reigning theory of how subatomic particles behave (see “Catch Me if You Can” by Karen Wright, Discover, July 2005). The standard model is perhaps the most successful quantum theory, explaining every subatomic interaction witnessed so far, but it merely whets the appetite of string theorists. They believe the standard model is contrived, ugly, and incomplete because it contains at least 19 adjustable parameters, three near-identical copies of subatomic particles, and no description of gravity.Superstring theory holds that the standard model describes only the lowest vibration modes of the strings. In this view, the standard model does a good job describing the world we know, yet it is unfinished. Nevertheless, the standard model has worked as a viable theory for decades. The discovery of sparticles would mark its first failure to adequately explain the tiny quantum world and would unleash an avalanche of new tests by experimental particle physicists, who sometimes deride string theory as too abstract. Sparticles would not, however, seal the deal on string theory. Some physics theories explain the existence of sparticle-like particles without resorting to strings.The Large Hadron Collider could support string theory in other ways. For instance, it might create miniature black holes predicted by one version of the theory; these in turn would produce telltale showers of subatomic particles as they disintegrated. (Physicists say the black holes are so small they pose no danger of swallowing up Switzerland and the rest of Earth.) The collider may also be powerful enough to test one of the most bizarre predictions of string theory—that there are
