Flipswitch.js - DEMO

Pure ES6 library for clipping fixed positioned elements on scroll

🔨️ Why

• allows to clip fixed elements trough sections on scroll
• it's simple to use
• lightweight (minified ~8kb)
• fast and customizable
• no dependencies

📦 Getting Started

• install flipswitch trough npm or pull ti from git

npm i @bornfight/flipswitch

• include flipswitch to your JS and SCSS after running npm install

JS

import Flipswitch from "@bornfight/flipswitch";

SCSS

@import "~flipswitch/src/scss/flipswitch.scss";

or CSS

<link rel="stylesheet" href="flipswitch.css">

💎 Customization

HTML markup

• data-flipswitch-class doesn't need to be different for every section (could be something like dark and light)

<p class="js-flipswitch-element">
    Flipswitch element
</p>

<section class="js-flipswitch-section" data-flipswitch-class="first-section">
    ...
</section>
<section class="js-flipswitch-section" data-flipswitch-class="second-section">
    ...
</section>
<section class="js-flipswitch-section" data-flipswitch-class="fourth-section">
    ...
</section>

<!-- default section -->
<section class="js-flipswitch-section">
    ...
</section>

Basic usage

• element needs to have js-flipswitch-element class
• section needs to have js-flipswitch-section class and data-flipswitch-class attribute
• data-flipswitch-class is a flag that will define witch element will be clipped
• library will use requestAnimationFrame() (not scroll event)
• element will be wrapped and positioned to body

new Flipswitch();

Advanced usage

• below example will use scroll event
• element will be wrapped and positioned to js-parent
• element is offset by 50px from left and -50px from top

new Flipswitch({
    parentClass: 'js-parent',
    elementClass: 'js-element',
    sectionsClass: 'js-section',
    useScroll: true,
    offsetX: 50,
    offsetY: -50
});

🚀 Useful to know

1. every section needs to have data-flipswitch-class (look 4.) and section class (default is js-flipswitch-section)
2. data-flipswitch-class is added to element wrapper as modifier class
3. element needs to be position: fixed
4. every second section doesn't need to have data-flipswitch-class - default class (and element clone) is available
5. every element needs to have it's own Flipswitch instance (and different sections and element classes)
6. throttle is only available if useScroll is false and value have to be in milliseconds
7. first section on page needs to have class js-flipswitch-section but doesn't needs to have data-flipswitch-class attr
