Petunjuk Cara Membuat Efek Salju Turun Di Blog atau Situs Web
1.Untuk menambah Efek salju, Cari tag <body> dan tempelkan kode dibawah ini sesudah tag tersebut. Atau bisa ditaruh sebelum/di atasnya tag </body>

<style> #snowflakeContainer { position: absolute; left: 0px; top: 0px; } .snowflake { padding-left: 15px; font-family: Cambria, Georgia, serif; font-size: 14px; line-height: 24px; position: fixed; color: #FFFFFF; user-select: none; z-index: 1000; -moz-user-select: none; -ms-user-select: none; -khtml-user-select: none; -webkit-user-select: none; -webkit-touch-callout: none; } .snowflake:hover { cursor: default; } </style> <div id='snowflakeContainer'> <p class='snowflake'>*</p> </div> <script>// The star of every good animation var requestAnimationFrame = window.requestAnimationFrame || window.mozRequestAnimationFrame || window.webkitRequestAnimationFrame || window.msRequestAnimationFrame; var transforms = [&quot;transform&quot;, &quot;msTransform&quot;, &quot;webkitTransform&quot;, &quot;mozTransform&quot;, &quot;oTransform&quot;]; var transformProperty = getSupportedPropertyName(transforms); // Array to store our Snowflake objects var snowflakes = []; // Global variables to store our browser&#39;s window size var browserWidth; var browserHeight; // Specify the number of snowflakes you want visible var numberOfSnowflakes = 50; // Flag to reset the position of the snowflakes var resetPosition = false; // // It all starts here... // function setup() { window.addEventListener(&quot;DOMContentLoaded&quot;, generateSnowflakes, false); window.addEventListener(&quot;resize&quot;, setResetFlag, false); } setup(); // // Vendor prefix management // function getSupportedPropertyName(properties) { for (var i = 0; i &lt; properties.length; i++) { if (typeof document.body.style[properties[i]] != &quot;undefined&quot;) { return properties[i]; } } return null; } // // Constructor for our Snowflake object // function Snowflake(element, radius, speed, xPos, yPos) { // set initial snowflake properties this.element = element; this.radius = radius; this.speed = speed; this.xPos = xPos; this.yPos = yPos; // declare variables used for snowflake&#39;s motion this.counter = 0; this.sign = Math.random() &lt; 0.5 ? 1 : -1; // setting an initial opacity and size for our snowflake this.element.style.opacity = .1 + Math.random(); this.element.style.fontSize = 12 + Math.random() * 50 + &quot;px&quot;; } // // The function responsible for actually moving our snowflake // Snowflake.prototype.update = function () { // using some trigonometry to determine our x and y position this.counter += this.speed / 5000; this.xPos += this.sign * this.speed * Math.cos(this.counter) / 40; this.yPos += Math.sin(this.counter) / 40 + this.speed / 30; // setting our snowflake&#39;s position setTranslate3DTransform(this.element, Math.round(this.xPos), Math.round(this.yPos)); // if snowflake goes below the browser window, move it back to the top if (this.yPos &gt; browserHeight) { this.yPos = -50; } } // // A performant way to set your snowflake&#39;s position // function setTranslate3DTransform(element, xPosition, yPosition) { var val = &quot;translate3d(&quot; + xPosition + &quot;px, &quot; + yPosition + &quot;px&quot; + &quot;, 0)&quot;; element.style[transformProperty] = val; } // // The function responsible for creating the snowflake // function generateSnowflakes() { // get our snowflake element from the DOM and store it var originalSnowflake = document.querySelector(&quot;.snowflake&quot;); // access our snowflake element&#39;s parent container var snowflakeContainer = originalSnowflake.parentNode; // get our browser&#39;s size browserWidth = document.documentElement.clientWidth; browserHeight = document.documentElement.clientHeight; // create each individual snowflake for (var i = 0; i &lt; numberOfSnowflakes; i++) { // clone our original snowflake and add it to snowflakeContainer var snowflakeCopy = originalSnowflake.cloneNode(true); snowflakeContainer.appendChild(snowflakeCopy); // set our snowflake&#39;s initial position and related properties var initialXPos = getPosition(50, browserWidth); var initialYPos = getPosition(50, browserHeight); var speed = 5+Math.random()*40; var radius = 4+Math.random()*10; // create our Snowflake object var snowflakeObject = new Snowflake(snowflakeCopy, radius, speed, initialXPos, initialYPos); snowflakes.push(snowflakeObject); } // remove the original snowflake because we no longer need it visible snowflakeContainer.removeChild(originalSnowflake); // call the moveSnowflakes function every 30 milliseconds moveSnowflakes(); } // // Responsible for moving each snowflake by calling its update function // function moveSnowflakes() { for (var i = 0; i &lt; snowflakes.length; i++) { var snowflake = snowflakes[i]; snowflake.update(); } // Reset the position of all the snowflakes to a new value if (resetPosition) { browserWidth = document.documentElement.clientWidth; browserHeight = document.documentElement.clientHeight; for (var i = 0; i &lt; snowflakes.length; i++) { var snowflake = snowflakes[i]; snowflake.xPos = getPosition(50, browserWidth); snowflake.yPos = getPosition(50, browserHeight); } resetPosition = false; } requestAnimationFrame(moveSnowflakes); } // // This function returns a number between (maximum - offset) and (maximum + offset) // function getPosition(offset, size) { return Math.round(-1*offset + Math.random() * (size+2*offset)); } // // Trigger a reset of all the snowflakes&#39; positions // function setResetFlag(e) { resetPosition = true; }</script>

Setelah Itu klik "Simpan" Dan lihat hasilnya. 

Itu saja, Sangat mudah bukan?
