A Vibrant Text Banner: Bringing Words to Life with JavaScript

This blog post explores a captivating technique for animating text, transforming simple words into a dynamic and eye-catching visual experience. We’ll delve into the code provided, breaking down its functionality and highlighting its creative potential.

The Concept:

The code creates an animated text banner, where each letter of the phrase “Cool Animated Text Banner” is individually manipulated, resulting in a vibrant and engaging visual display. This effect is achieved through JavaScript, dynamically altering the position, color, and styling of each letter over time.

Code Breakdown:

  1. HTML Structure:
   <link rel="preconnect" href="https://fonts.googleapis.com">
   <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
   <link href="https://fonts.googleapis.com/css2?family=Lacquer&display=swap" rel="stylesheet">

   <a href="https://411center.com/r/codepen" target="_blank">
       <div class="rugrats">Cool &nbsp; Animated</div>
   <div class="rugrats">Text &nbsp; Banner</div>
   </a>
  • The code sets up a basic HTML structure with two <div> elements, each containing a part of the phrase “Cool Animated Text Banner.” The elements are wrapped in an <a> tag for linking purposes.
  1. CSS Styling:
   body {
       margin: 12vh;
       text-align: center;
       font-size: calc(8vw + 8vh);
       background: #314d79;
       color: #fff;
       font-family: sans-serif;
       letter-spacing: -0.3vw;
       overflow: hidden;
       font-family: "Lacquer", system-ui;
   }

   .rugrats {
       margin: 0 auto;
       text-align: center;
       overflow: hidden;
       white-space: nowrap;
   }
   .rugrats span {
       display: inline-block;
       transition: color linear 0.5s forwards;
       -webkit-text-stroke-width: 0.32vw;
       -webkit-text-stroke-color: black;
       text-shadow: 0.4vw 0.5vw #000;
   }

   .rugrats span {
       text-transform: capitalize;
       text-transform: lowercase;
       /*  animation:caseChange 5s ease infinite forwards;
   }
   @keyframes caseChange{
       from{
           text-transform:uppercase;
       }
       to{
           text-transform:lowercase;
       }
   } */
   }
  • The CSS styles the body and the rugrats divs, setting up the background, font, and text alignment. It also styles the individual letters (span) within the divs, adding a text stroke and shadow for a visually striking effect.
  1. JavaScript Animation:
   var divs = document.querySelectorAll(".rugrats");

   divs.forEach(function (div) {
       var text = div.textContent;
       div.innerHTML = "";

       for (var i = 0; i < text.length; i++) {
           var span = document.createElement("span");
           span.textContent = text[i];
           div.appendChild(span);
       }

       var spans = div.querySelectorAll("span");

       function shuffle(array) {
           for (var i = array.length - 1; i > 0; i--) {
               var j = Math.floor(Math.random() * (i + 1));
               var temp = array[i];
               array[i] = array[j];
               array[j] = temp;
           }
           return array;
       }

       spans = shuffle(Array.from(spans));

       function getRandomValue() {
           return Math.random() * 0.4 - 0.24;
       }

       function applyRandomTransform() {
           spans.forEach(function (span) {
               var xOffset = getRandomValue() * 10;
               var yOffset = getRandomValue() * 15;
               var rotation = getRandomValue() * 6;

               span.style.transform =
                   "translate(" +
                   xOffset +
                   "px, " +
                   yOffset +
                   "px) rotate(" +
                   rotation +
                   "deg)";
               span.style.textIndent = xOffset + "px";
           });
       }

       function getRandomColor() {
           var letters = "0123456789ABCDEF";
           var color = "#";
           for (var i = 0; i < 6; i++) {
               color += letters[Math.floor(Math.random() * 16)];
           }
           return color;
       }

       var currentIndex = 0;

       function changeColorSequentially() {
           spans.forEach(function (span, index) {
               var colorIndex = (index + currentIndex) % spans.length;
               span.style.color =
                   colorIndex === 0 ? getRandomColor() : spans[colorIndex - 1].style.color;
           });

           currentIndex = (currentIndex + 1) % spans.length;
       }

       setInterval(changeColorSequentially, 250);
       setInterval(applyRandomTransform, 100);
   });
  • The JavaScript code iterates through each div element, breaking down the text into individual letters (span) and shuffling their order.
  • It then applies random transformations (translation, rotation, and text indent) to each letter at regular intervals.
  • Finally, it cycles through the letters, changing their color sequentially, creating a dynamic and colorful effect.

Key Features:

  • Dynamic Text: Each letter is treated as an independent element, allowing for unique and unpredictable animation.
  • Randomized Transformations: The use of random values for translation, rotation, and text indent creates a visually engaging and unpredictable effect.
  • Sequential Color Changes: The color of each letter changes in a sequential manner, adding a dynamic and vibrant element to the animation.

Possible Enhancements:

  • More Complex Animations: Explore more sophisticated animation techniques like easing functions or particle effects.
  • Interactive Elements: Allow users to adjust the speed of the animation, the color palette, or even the text itself.
  • Responsive Design: Ensure the animation adapts seamlessly to different screen sizes and resolutions.
