• Implementation: PowerGlitch can be installed using package managers like npm or yarn, or by importing the web bundle in a script tag.

• Usage: To use PowerGlitch, you need to find the HTML element that you want to apply the glitch effect to, and add the 'glitch' class to it. Then, initialize the glitch effect using the PowerGlitch.glitch('.glitch') command.

• Customization: The library offers customization and optimization tips that can be found in the usage guide.

KinesisJS is a JavaScript library primarily used for managing and simulating animations or dynamic interactions based on mouse movements or scroll events. Here are its main features:

Parallax Effects

• Mouse movement-based animations: Allows elements to move at different speeds in response to mouse movements, creating a sense of depth.

• Scroll effects: Elements can move or animate based on the page's scroll position.

Easy Configuration

• Animations can be easily configured through simple options or by applying attributes to HTML elements.

• Supports parameters such as direction, speed, and movement boundaries.

Layer Management

• KinesisJS enables defining multiple layers of elements for complex parallax effects. Each layer can have specific speed and direction settings.

Responsiveness

• Compatible with responsive environments, adapting to screen sizes and orientations to maintain effects on mobile devices and tablets.

Optimized Performance

• Utilizes requestAnimationFrame for smooth and efficient animations, reducing system resource consumption.

Customizable Interactions

• Allows specific triggers to be set (e.g., activating effects only after a certain scroll point or when the mouse enters a defined area).

Support for Non-linear Transitions

• Animations can include transitions with acceleration/deceleration curves for more natural and customized effects.

Typical Use Cases:

• Creating interactive websites with impressive visual animations.

• Adding parallax effects to enhance a page's aesthetics and user experience.

• Animating specific elements to draw attention to content or guide the user.

i-HTML fetches a requested HTML resource and replaces the element's inner contents with the parsed content of the response. It's similar to an <iframe> but adopts the HTML into the page.

Key functionalities and features of <i-html> include:

• Basic Usage: The <i-html> tag is placed as an empty container, and when the src= attribute changes, it fetches the HTML and updates the content.

• Targeting with Links: Like iframes, <i-html> respects the target= attribute on links, so a link with a target that matches the id of an <i-html> element will load the link's href into the element.

• Targeting with Forms: Similarly, <i-html> respects target= attributes on forms, allowing forms to submit to an <i-html> element and load new content. Forms can also be wrapped in <i-html> elements to create "AJAX-style" forms. The formaction= attribute of buttons is also supported.

• Content Selection: By default, <i-html> injects the <body> element's content but this can be customized with the target= attribute, which uses a querySelector to select specific content.

• Refetching: Content can be refetched by clicking a link or by using a <button command="--load"> element. The Refresh header or <meta http-equiv=refresh> tag in the response can also trigger a refresh.

• Content Negotiation: The accept= attribute allows customization of the Accept header in the request, limited to text/plain, text/html, image/svg+xml, and application/xml. Invalid MIME types default to text/html.

• Streaming: With accept="text/event-stream", <i-html> uses EventSource to listen for Server-Side Events, allowing for multiple content updates with a single request.

• Insertion Modes: Content can be appended (insert="append") or prepended (insert="prepend") to existing content instead of replacing it.

• Deferring Loading: The loading= attribute can be set to lazy to defer loading until the element is visible, or to none to prevent loading until changed via JavaScript. A <button command="--load"> can force loading regardless of the loading attribute.

• Security: <i-html> uses fetch() and adheres to CORS policies. By default, it only fetches same-origin URLs. The allow="cross-origin" attribute allows cross-origin requests. Several elements, such as <iframe>, <script>, and <style> are sanitized out by default, unless specifically allowed with the allow attribute.

• Declarative Shadow DOM: <i-html> supports declarative shadow DOM (DSD) if the browser supports Document.parseHTMLUnsafe. Older browsers require a polyfill.

• Styling: The element has pseudo-classes (:waiting, :loading, :loaded, and :error) for styling during different stages of its lifecycle, and uses attributes like [state-waiting] in older browsers.

• Events: <i-html> dispatches events such as loadstart, load, loadend, error, beforeinsert, and inserted during its lifecycle. The loadstart event can be used to customize the request or prevent loading. The beforeinsert event can modify or prevent content insertion.

<i-html> aims to combine the best features of similar elements, like include-fragment, and offers more functionality than other options like htmx or htmz. It remains in the DOM and can refetch content, unlike <include-fragment> which replaces itself.

Features:

• Customizable CSS property prefixes. For example, the prefix for "display" can be changed from "dis" to "d".

• Optional custom value names. For instance, the value "flex" can be associated with the custom name "fx".

• Selective addition of !important keyword utility classes. By setting generate_utility to true, utility classes with !important can be generated for each CSS property.

• Responsive design on-demand. Users can set screen sizes and apply CSS properties selectively for each size. Responsive settings are defined in the screenSizes object. The responsive property can be set to true or false for each CSS property.

• Use of tokens. Tokens are lists of names associated with values, organized by families, and reusable. Tokens prevent repeating the same names and values across multiple CSS properties. Each token is written as a CSS variable.

• CSS variables that are automatically generated.

• Automatic documentation of the CSS output. An interactive documentation is generated automatically.

• Instant file size impact of the settings.

• Offline functionality.

To get started, users need to download the starter project, edit the build.json file, and run it through a browser. The tool requires only a text editor, a web server, and a browser. The JSON settings include:

• separator: A string to split names, values, and utility prefixes.

• responsiveSeparator: A string to split screen size names.

• utilitiesPrefix: A string for utility classes.

• cssVariablesPrefix: A string used for tokens' CSS variables.

• screenSizes: An object that defines screen sizes.

The JSON tokens are lists of names associated with values, organized by families. Tokens are optional and can be left empty if unused.

The JSON properties object has keys that are valid CSS property names. Each CSS property has a prefix, generate_from to refer to a token, a list of values, an optional list of names, responsive which is a boolean, and a generate_utility boolean to generate utility classes.
