    Bootstrap Native

    Bootstrap Native

    If you are looking for Bootstrap without jQuery, this is it.

    The lighter and more compact set of JavaScript components for Bootstrap is sourced with a modern ES6+ codebase and strong TypeScript definitions. At about half the size of the original and around 12kb gZipped, this library does most of Bootstrap & Popper combined. We launched the project back in 2015 with the goal of debunking the "write less do more" myth, meanwhile the Bootstrap developers themselves have decided to drop jQuery, however, we decided to keep maintaining the project for its many benefits and the learning experience. If you mainly use Bootstrap plugins for your projects, why not use a much lighter, potentially faster library, see a different perspective on the same challenges, interact with a less crowded community, and get a better chance to learn or say hi! The Alert component covers the specific original events and public methods, but just like the original plugin, does not provide any initialization option.

    D3

    D3

    Bring data to life with SVG, Canvas and HTML

    D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation. D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. D3 is not a monolithic framework that seeks to provide every conceivable feature. Instead, D3 solves the crux of the problem: efficient manipulation of documents based on data. This avoids proprietary representation and affords extraordinary flexibility, exposing the full capabilities of web standards such as HTML, SVG, and CSS.

    DutyCrew

    DutyCrew

    Builds websites, styles, uploads via a simple web interface. Mac Win

    Well used (on Mac, have just resurrected Windows variant) X-platform web development tool that permits site sharing via exports/import zip files of pretty much any web site you care to develop. It can be easily exported between platforms, even look/feel styles (css) can be exchanged in the same manner. If you hit problems, please let me know and I can then try to fix them. I have had a stroke and am operating with a greatly reduced mental stamina, and I can't think clearly for very long as a result, rather like having a low battery!. Basically this is a language independent multilingual English (US & UK), Welsh and any others that can be thought of (help still needed on the translation process) tool. Just 1 button and the whole interface changes language! Free but we are hopeful of gaining enough supporters to make the whole project viable via donations. Try it, you'll like it! It has taken many years of work on my own to get it to this stage, I look forward to seeing it grow.

    Gutenberg Typography Kit

    Gutenberg Typography Kit

    A meaningful web typography starter kit

    Gutenberg is a flexible and simple-to-use web typography starter kit for web designers and developers. It’s a small step towards a better typography on the web. Beautiful typographic styles can be made by setting base type size, line height (leading), and measure (max-width). Gutenberg is a work-in-progress project by Matej Latin that brings meaning and craftsmanship to web typography. The reader should be able to read the message of a text easily and comfortably. This depends to a not inconsiderable extent on the size of the type, the length of the lines and the leading. Gutenberg sets the baseline grid to establish a proper vertical rhythm and makes sure all elements fit into it. It sets up the macro typography so you can focus on the micro–typographic details. All calculations in Gutenberg depend on base type size and line-height. Multiplication of these two results in leading which is essential for setting a correct vertical rhythm and a baseline grid.
