# css-development Gives Claude a CSS workflow: Tailwind classes built by composition, meaningful names, dark mode as the default. Useful once stylesheets start to sprawl. - plugin · `type=plugin` · Claude Code · ★ 97 - Author: 2389-research - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/2389-research/claude-plugins/tree/HEAD/css-development - Updated: 2026-10-21 - HTML: https://affpapa.org/en/nevibecode/plugins/css-development ## What it does The plugin sets three habits for CSS work. Tailwind classes get assembled from parts instead of one long line, class names carry meaning, and dark mode is the starting point. The agent follows those habits whenever it writes or edits styles. It ships as a `claude-community` marketplace entry with a workflow description only. You install it the usual marketplace way and configure nothing else. On a plain-CSS project without Tailwind the composition rule has nothing to act on, because it assumes a utility-first setup. Dark mode by default means any light theme has to be spelled out. Fine for something new. On an existing light-only interface, look at what changes in your styles first. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-community ``` In the agent chat (not a shell): ```text /plugin install css-development@claude-community ``` ## When to use it - keep long Tailwind class strings readable - name CSS classes after what they do - make dark mode the base state, not an add-on - hold one CSS style while an agent edits the code ## Example prompts - Build the product card using the plugin's rules: composed Tailwind classes, meaningful names, dark mode by default - Rework `styles.css`: split the long Tailwind class strings into parts and name them clearly - Add a light theme on top of the default dark one in this component ## Source text · css-development · MIT Below is the content of a third-party file.
