Welcome to the world of Restyle.js! If you’ve ever wished for a lightweight way to manipulate your web application’s styling, you’re in the right place. Inspired by libraries like absurd.js, Restyle.js packs powerful features into a tiny package of about 1KB. This guide will walk you through how to get started with Restyle.js, including some troubleshooting tips along the way.

What is Restyle.js?

Restyle.js is a JavaScript library designed to make DOM styling easier and more flexible, allowing you to write CSS-like rules directly in JavaScript. It simplifies the process of dynamically applying styles to your webpage without the need for bulky CSS files. Just think of it like a magical paintbrush that lets you paint CSS styles on your web application in real-time.

Setting Up Restyle.js

First, ensure that you have included Restyle.js in your project. You can easily integrate it with a simple script tag:

<script src="path/to/restyle.js"></script>

Creating Styles Dynamically

With Restyle.js, you can define styles in a JavaScript function. Here’s how it works:

Imagine you run a bakery, and every cake you make requires specific decorations. Instead of always following a predefined recipe, you want to create decorations based on the day’s theme (e.g., chocolate, sprinkles, or fruits). Restyle.js allows you to create these “decorations” dynamically based on conditions you set in your function.

Here’s an example of how you would use it:

var myStyle = (function() {
  function getSomeNumber(boundary) {
    return Math.floor(Math.random() * (boundary + 1));
  }

  function hex(red, green, blue) {
    return '#'.concat(
      (0 + red.toString(16)).slice(-2),
      (0 + green.toString(16)).slice(-2),
      (0 + blue.toString(16)).slice(-2)
    );
  }

  return restyle({
    body: {
      backgroundColor: hex(100, 60, 25),
      padding: {
        top: 50,
        left: '30%'
      }
    },
    '.component li': {
      width: window.innerWidth,
      height: getSomeNumber(200)
    },
    '.component .icon-spinner': {
      animation: {
        name: 'spin',
        duration: '4s'
      }
    },
    '@keyframes spin': {
      from: {
        transform: 'rotate(0deg)'
      },
      to: {
        transform: 'rotate(360deg)'
      }
    }
  });
})();

In this example, each time you run the `myStyle` function, it’s like baking a new themed cake. The styles generated are specific to that moment, and you can adjust them dynamically based on runtime conditions, such as browser width or user interaction.

Removing Styles with Ease

One of the coolest features of Restyle.js is that you can remove all styles applied at any time! It’s like cleaning your workspace after a baking session.

myStyle.remove();

New Features and Upgrades

Restyle.js continually evolves, and new updates bring powerful methods for smoother animations and transitions. As of version 0.4, for example, you can easily set up transitions!

var transition = restyle.transition(genericElement, {
  from: { opacity: 0, height: 34 },
  to: { opacity: 1 },
  onTransitionEnd: function(e) {
    console.log('transition completed');
    e.detail.clean();
  }
});

Troubleshooting Tips

• Style isn’t applying: Double-check that Restyle.js is correctly linked in your HTML file and that your styles are correctly defined in the JavaScript.
• Changes aren’t updating: Make sure you’re calling your style function correctly and that you’re not caching styles inadvertently.
• Remove function not working: If the `remove` function is not triggering as expected, confirm that you’ve saved a reference to your styles (like `myStyle` in this guide) before calling it.
