The code Vanilla JS code snippet helps you to create an animated weather card. It allows you to display weather conditions with animations on a web page.
The major functionalities include:
- Displaying weather conditions such as snow, wind, rain, thunder, and sunny weather.
- Animating raindrops, snowflakes, leaves, and clouds based on the selected weather condition.
- Providing a visually appealing weather summary card with temperature, date, and weather description.
This code helps you create an interactive and visually engaging weather display on your website.
How to Create Animated Weather Card In Vanilla Js
1. In your HTML file, create a structure for your weather card. You’ll need a container for the card, a location label, a temperature display, and an element for the animated weather icon.
<div class="background"> <div class="container"> <svg id="back"> <radialGradient id="SVGID_1_" cx="0" cy="0" r="320.8304" gradientUnits="userSpaceOnUse"> <stop offset="0" style="stop-color:#FFDE17;stop-opacity:0.7"/> <stop offset="1" style="stop-color:#FFF200;stop-opacity:0"/> </radialGradient> <path id="sunburst" style="fill:url(#SVGID_1_);" d="M0,319.7c-18.6,0-37.3-1.6-55.5-4.8L-7.8,41.4c5.1,0.9,10.6,0.9,15.7,0L56,314.8C37.6,318,18.8,319.7,0,319.7z M-160.8,276.6c-32.5-18.8-61.3-42.9-85.5-71.6L-34,26.2c3.4,4.1,7.4,7.4,12,10.1L-160.8,276.6z M161.3,276.4L22.1,36.2 c4.5-2.6,8.6-6,12-10.1l212.6,178.5C222.5,233.4,193.8,257.6,161.3,276.4z M-302.5,108.3C-315.4,73-321.9,36-322-1.8l277.6-0.5 c0,5.3,0.9,10.4,2.7,15.2L-302.5,108.3z M302.6,107.8L41.8,12.8c1.7-4.7,2.6-9.7,2.6-14.9c0-0.3,0-0.6,0-1H322l0-1.3l0,1.9 C322,35.4,315.5,72.5,302.6,107.8z M-41.8-17.5l-261-94.5c12.8-35.4,31.6-68,55.8-96.9L-34.1-30.8C-37.5-26.8-40.1-22.3-41.8-17.5z M41.7-17.7c-1.8-4.8-4.4-9.3-7.8-13.3l212-179.2c24.3,28.8,43.3,61.3,56.3,96.6L41.7-17.7z M-22.2-40.8l-139.6-240 c32.7-19,68.1-32,105.2-38.6L-8-46.1C-13-45.2-17.8-43.4-22.2-40.8z M22-40.9c-4.4-2.6-9.2-4.3-14.2-5.1l47.1-273.6 c37.2,6.4,72.7,19.2,105.4,38L22-40.9z"/> </svg> <nav> <ul> <li><a id="button-snow" class="active"><i class="wi wi-snow"></i></a></li> <li><a id="button-wind"><i class="wi wi-strong-wind"></i></a></li> <li><a id="button-rain"><i class="wi wi-rain"></i></a></li> <li><a id="button-thunder"><i class="wi wi-lightning"></i></a></li> <li><a id="button-sun"><i class="wi wi-day-sunny"></i></a></li> </ul> </nav> <div id="card" class="weather"> <svg id="inner"> <defs> <path id="leaf" d="M41.9,56.3l0.1-2.5c0,0,4.6-1.2,5.6-2.2c1-1,3.6-13,12-15.6c9.7-3.1,19.9-2,26.1-2.1c2.7,0-10,23.9-20.5,25 c-7.5,0.8-17.2-5.1-17.2-5.1L41.9,56.3z"/> </defs> <circle id="sun" style="fill: #F7ED47" cx="0" cy="0" r="50"/> <g id="layer3"></g> <g id="cloud3" class="cloud"></g> <g id="layer2"></g> <g id="cloud2" class="cloud"></g> <g id="layer1"></g> <g id="cloud1" class="cloud"></g> </svg> <div class="details"> <div class="temp">20<span>c</span></div> <div class="right"> <div id="date">Monday 22 August</div> <div id="summary"></div> </div> </div> </div> <svg id="outer"></svg> </div> </div>
2. Create a “styles.css” file to style your weather card and the animated weather icon. Customize the styles according to your preferences.
@import 'https://fonts.googleapis.com/css?family=Lato:300'; @import 'https://cdnjs.cloudflare.com/ajax/libs/weather-icons/2.0.9/css/weather-icons.min.css'; html, body, .background { width: 100%; height: 100%; margin: 0; padding: 0; font-family: "Lato", sans-serif; } html { background: #fff; } body { background: #eee; background: linear-gradient(0deg, rgba(0, 0, 200, 0.2), rgba(0, 0, 200, 0)); } .background { background: #eee; background: linear-gradient(120deg, rgba(50, 150, 100, 0.2), rgba(0, 0, 100, 0)); } .container { display: flex; flex-direction: column; align-items: center; justify-content: center; margin: 0; padding: 0; height: 100%; width: 100%; overflow: auto; position: relative; background: #eee; background: linear-gradient(240deg, rgba(150, 50, 50, 0.3), rgba(0, 0, 200, 0)); } nav ul { margin: 20px 20px 0 20px; list-style-type: none; padding: 0; display: flex; flex-direction: row; } nav li a { display: block; width: 50px; text-align: center; color: #aaa; cursor: pointer; } nav li a:hover { color: #444; } nav li a.active { color: #4444ff; } #card { box-shadow: 9px 7px 40px -6px rgba(0, 0, 0, 0.25); overflow: hidden; width: 300px; padding: 0; height: 400px; min-height: 300px; margin: 20px; border-radius: 5px; position: relative; } #card .details { position: absolute; top: 0; left: 0; right: 0; padding: 16px 20px; color: #888; display: flex; flex-direction: row; justify-content: space-between; transition: color 2s ease; } .thunder #card .details { color: #ddd; } #card .details .right { text-align: right; } #card .details #date { margin: 4px 0; } #card .details #summary { font-weight: 600; font-size: 22px; } #card .details .temp { font-size: 60px; line-height: 60px; } #card .details .temp span { font-size: 18px; line-height: 30px; vertical-align: top; margin-left: 5px; } .weather { background-color: #DAE3FD; transition: background-color 2s ease; } .thunder .weather { background-color: #9FA4AD; } .rain .weather { background-color: #D8D8D8; } .sun .weather { background-color: #ccccff; } .weather #inner { background-color: white; background: linear-gradient(to bottom, rgba(255, 255, 255, 0.5) 50%, rgba(255, 255, 255, 0) 100%); } .weather .cloud { transition: fill 2s ease; } .weather #cloud1 { fill: #efefef; } .thunder .weather #cloud1 { fill: #9FA4AD; } .weather #cloud2 { fill: #E6E6E6; } .thunder .weather #cloud2 { fill: #8B8E98; } .weather #cloud3 { fill: #D5D5D5; } .thunder .weather #cloud3 { fill: #7B7988; } #outer, #back { position: fixed; pointer-events: none; }
3. Now, load the jQuery, TweenMax JS, and Snap SVG JS by adding the following scripts before closing the body tag:
<script src='https://code.jquery.com/jquery-2.2.4.min.js'></script> <script src='https://cdnjs.cloudflare.com/ajax/libs/gsap/1.19.0/TweenMax.min.js'></script> <script src='https://cdnjs.cloudflare.com/ajax/libs/snap.svg/0.4.1/snap.svg-min.js'></script> <script src='https://codepen.io/ste-vg/pen/zBVaZw.js'></script>
4. Create a "script.js"
file to handle fetching weather data and updating the card. You can use a weather API like OpenWeatherMap to get real weather data.
