    HyperUI

    HyperUI

    Free Tailwind CSS v4 components for your next project

    ...It groups components by common product needs—navigation, hero sections, pricing, forms, cards, tables, and full e-commerce flows—so teams can assemble pages quickly from consistent building blocks. Each snippet is written as semantic HTML with Tailwind utility classes, making it easy to customize spacing, color, and typography through a project’s Tailwind config. The components are responsive by default, using grid and flex patterns that adapt cleanly from mobile to widescreen layouts. Accessibility is treated pragmatically: markup favors proper roles and focus states, and most interactive behaviors can be wired with lightweight libraries or framework code if desired. ...

    Twemoji

    Twemoji

    Simple library that provides standard Unicode emoji for all platforms

    ...The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.
