Dark Mode

To enable automated dark mode support add below Tailwind variant in your Tailwind entry file style.css:

@custom-variant dark (&:is(.dark *));

---

Styles

Include KTUI styles in your Tailwind entry file style.css:

@import "./node_modules/@keenthemes/ktui/dist/styles.css";

---

Font

Specify a font family of your choice in your Tailwind entry file style.css:

@theme  {
    --default-font-family: Inter;
}

Include the font file:

    
        ...
        
        ...
    
    
        ....
    

---

Assets

Include KTUI JavaScript, Tailwind CSS, and fonts:

    
        ...
        
        
        ...
    
    
        ....
    
    

---

RTL Support

To globally setup the RTL direction add a dir="rtl" attribute on the html as shown below:

KTUI utilizes the logical CSS properties as the default method for handling RTL support. This approach simplifies RTL support by using context-aware properties that adjust based on the document’s text direction.

For specific cases, you can use the rtl:* Tailwind modifier to easily control alignments for both LTR and RTL directions.

---

Agent skills

KTUI ships Agent Skills so that agentic coding tools (e.g. Cursor, Claude Code) can use KtUI correctly—imports, init pattern, and docs. You can install skills in two ways; both use the same content from this package.

Available skills

Install from npm (recommended)

After installing the package, copy or symlink the skills you need from the package into your project or your agent’s skills directory:

• Location: node_modules/@keenthemes/ktui/skills/
• Example (Cursor): Copy or symlink a skill into .cursor/skills/, e.g.
  cp -r node_modules/@keenthemes/ktui/skills/ktui .cursor/skills/

Install via CLI (skills CLI)

You can also install from the GitHub repo using the skills CLI (no separate registration required). The repo must contain a top-level skills/ directory with skill subfolders, each having a valid SKILL.md; once that is on the default branch, run:

npx skills add keenthemes/ktui

Choose the Symlink option when prompted to keep one copy and simplify updates. Both this method and the npm copy above provide the same skill content. Skills appear on the skills.sh leaderboard automatically as users install them (anonymous telemetry).
