CSS Grid Generator is a visual tool built to help web designers and developers quickly create CSS Grid layout code without writing the grid definitions manually. You select the number of columns, rows, and units (e.g., fr, px, %), then visually drag and place items, resize them and position them within the grid to prototype layouts by hand. Once the layout is arranged, the tool generates the corresponding HTML and CSS you can copy into your project—thus bridging the gap between design and code. The interface supports drag-and-drop of “divs” into grid cells, and you can experiment with grid gaps, spans and layout refinements in real time. Because it removes the barrier of hand-writing complex grid-template or grid-area definitions, it’s particularly useful for designers who are less comfortable with CSS or want rapid prototyping of grid layouts.

CSS-Inspiration is a living gallery of modern CSS effects and components that highlights what’s possible with pure CSS and minimal markup. The collection ranges from micro-interactions and loaders to 3D transforms, complex backgrounds, hover states, and text effects, each presented as a small, self-contained demo. Source code is front and center, encouraging developers to study, copy, and tweak snippets for their own projects. Many examples lean on contemporary features—custom properties, filters, blend modes, gradients, and keyframes—serving as both inspiration and a practical cookbook. Because each demo focuses on a single idea, it’s an effective way to learn new techniques without wading through a full framework. The project thrives on experimentation and community interest, making it a frequent reference for designers, front-end engineers, and educators who want visually striking yet lightweight solutions.

CSS Theme Change is a small utility for managing CSS theme toggling (such as light/dark mode) in web projects, designed to be lightweight, easy to integrate, and framework-agnostic. Instead of relying on heavy JavaScript frameworks or complex state management, it offers a simple API that listens to system preferences and UI interactions to swap theme classes or variables in real time. It can react to user toggles as well as automatically adapt to the user’s OS-level dark/light mode settings, helping developers build interfaces that feel modern and responsive without writing boilerplate theme code. Because it abstracts away cross-browser quirks and standardizes how CSS variables or classes are applied, it saves time and reduces bugs related to inconsistent theme behavior. It’s also modular and tiny in size, meaning it can be dropped into static sites, component libraries, or SPAs without significantly increasing bundle size.

Simply put, CSSgram is a library for editing your images with Instagram-like filters directly using CSS. What we're doing is adding filters to the images, as well as applying color and/or gradient overlays via various blending techniques to mimic filter effects. This means less manual image processing and more fun filter effects on the web! We are using pseudo-elements (i.e. :before and :after) to create the filter effects, so you must apply these filters on a containing element (i.e. not a content-block like <img>. The recommendation is to wrap your images in a <figure> tag. If you use custom naming in your CSS architecture, you can add the .scss files for the provided styles within your project and then @extend the filter effects within your style definitions. Mixins allow for multiple filter arguments to be passed into your classes. This is useful for if you want to add filters in addition to the ones provided (i.e. add a blur).

An agnostic, reactive & minimalist (3kb) JavaScript UI library with direct access to native DOM. Instead of pulling you into a library-specific magical world, CalDOM let you fully access the DOM directly while keeping the reactivity. So you could take full advantage of native APIs & mix it with other libraries to gain superior performance & flexibility in the development process. In essence, CalDOM is just a wrapper around the native Node/Element. The overall performance drop is about 0.04x compared to vanilla/pure JavaScript. This is based on averaged unit-level benchmarks in handling single & multiple-element instances: View Benchmark Results against Vanilla JS, jQuery, React JS, Vue & more.

Components shouldn’t be concerned with how data is fetched, updated, or cached. CanJS provides the right abstractions for your model code to be cleanly separated from your UI code. CanJS’s stache templating language can directly read the state and values from Promises. No need to write any extra code to determine whether a Promise is pending, resolved, or rejected. After data is created, updated, or destroyed, CanJS automatically updates your lists for you. Filtering and sorting are preserved, so you don’t have to manually update your lists or fetch the same data again. The model layer is responsible for making GET, POST, PUT, and DELETE requests to your backend. With your component UI code using the model’s standard interface to make requests, if the backend API changes, you only have to configure the model and not change every component that uses that backend API.

CAF (Cancelable Async Flows) is a small utility that brings cooperative cancellation to JavaScript async workflows. It wraps async generators or promise-returning functions so they can respond to a cancel signal and halt work early, preventing wasted CPU and stray side effects. The library encourages a disciplined pattern: pass a token into your task, periodically check it, and unwind gracefully when cancellation is requested. This approach avoids brittle timeouts and “fire-and-forget” leaks by making cancellation a first-class concern. CAF is framework-agnostic and pairs well with fetch, timers, or custom async primitives, giving you a consistent contract for stopping in-flight operations. The result is safer UI interactions and services that don’t keep doing work the user no longer needs.
