How to Use Stylus for Custom WordPress Styling
Step 1: Install Stylus
Ensure Node.js is installed, then install Stylus globally:
npm install -g stylus
Verify the installation:
stylus -v
Step 2: Set Up a Stylus Folder in Your WordPress Theme
Inside your WordPress theme or plugin folder, create the following structure:
wp-content/themes/my-theme/
│── assets/
│ ├── stylus/
│ │ ├── style.styl
│ │ ├── variables.styl
│ │ ├── mixins.styl
│ ├── css/
│ │ ├── style.css
│── functions.php
│── style.css
Step 3: Write Stylus Styles (style.styl)
Inside the stylus/ folder, create style.styl:
@import "variables"
@import "mixins"
body
background: @primary-bg
color: @text-color
.button
rounded-button(@primary-color, 8px)
Step 4: Define Variables (variables.styl)
@primary-bg = #f9f9f9
@primary-color = #0055a5
@text-color = #333
Step 5: Define Mixins (mixins.styl)
rounded-button(color, radius)
background: color
border-radius: radius
padding: 10px 15px
color: white
cursor: pointer
Step 6: Compile Stylus to CSS
Run the following command to compile Stylus to CSS:
stylus assets/stylus/style.styl -o assets/css/style.css
This generates a CSS file that can be used in WordPress.
Step 7: Enqueue Stylus Compiled CSS in WordPress
Open your functions.php file and add the following code:
function my_theme_enqueue_styles() {
wp_enqueue_style('custom-stylus-style', get_template_directory_uri() . '/assets/css/style.css');
}
add_action('wp_enqueue_scripts', 'my_theme_enqueue_styles');
Step 8: (Optional) Enqueue Stylus CSS for Admin Panel
If you’re styling the WordPress admin dashboard, add:
function my_admin_stylus_styles() {
wp_enqueue_style('admin-stylus-style', get_template_directory_uri() . '/assets/css/style.css');
}
add_action('admin_enqueue_scripts', 'my_admin_stylus_styles');
Best Practices for Custom WordPress Styling with Stylus
✔ Use Variables and Mixins – Make your styles reusable and maintainable.
✔ Minify CSS Output – Use the -c flag for minification:
stylus -c assets/stylus/style.styl -o assets/css/style.css
✔ Use Source Maps – Enable source maps for debugging:
stylus --sourcemap assets/stylus/style.styl -o assets/css/style.css
✔ Optimize Load Times – Enqueue CSS only where necessary to improve performance.
Frequently Asked Questions (FAQs)
1. Why use Stylus for WordPress instead of CSS or SASS?
Stylus offers a simplified syntax, advanced features, and built-in functions that make writing and managing CSS easier.
2. Can I use Stylus in WordPress without compiling it?
No, Stylus must be compiled into CSS before WordPress can use it.
3. How do I automate Stylus compilation in WordPress?
Use Gulp or Webpack to watch for file changes and auto-compile Stylus:

Create a gulpfile.js:
const gulp = require('gulp');
const stylus = require('gulp-stylus');
gulp.task('styles', function () {
return gulp.src('assets/stylus/style.styl')
.pipe(stylus({ compress: true }))
.pipe(gulp.dest('assets/css'));
});
gulp.task('watch', function () {
gulp.watch('assets/stylus/**/*.styl', gulp.series('styles'));
});
Run:
gulp watch
This automatically compiles Stylus whenever changes are made.
