pixelfit v2.0.1

Pixelfit

A lightweight and flexible screen adaptation library for mobile and large-screen devices, supporting responsive scaling and px-rem conversion.

Features

• Mobile adaptation: Automatically scales the root font size (rem) for mobile devices based on the design width.
• Large screen adaptation: Adapts target DOM elements to fit large screen resolutions using transform scaling.
• Utility methods: Includes px2rem and rem2px conversion utilities.
• Type-safe and error-proof: Handles invalid configurations gracefully with default values and validations.

Installation

Install pixelfit via npm:

npm install pixelfit

Usage

Importing the Library

import Pixelfit from 'pixelfit';

Quick Start

1. Mobile Screen Adaptation

const pixelfit = new Pixelfit({ type: 'm', width: 750 });
pixelfit.pixelfit(); // Automatically adapts to the device size

2. Large Screen Adaptation

const pixelfit = new Pixelfit({ 
  type: 'l', 
  width: 1920, 
  height: 1080, 
  target: document.getElementById('app') 
});
pixelfit.pixelfit(); // Adapts the target element for large screens

3. Converting px to rem

// Convert 100px to rem based on a design width of 750px
const remValue = Pixelfit.px2rem(100, 750);
console.log(remValue); // Output: rem value

4. Converting rem to px

// Convert 1rem to px based on a design width of 750px
const pxValue = Pixelfit.rem2px(1, 750);
console.log(pxValue); // Output: px value
