Modern CSS Workflow: Essential Tools for 2026

Professional CSS development requires the right tooling. Here's what you need in your workflow.

Essential Tools

1. PostCSS

module.exports = {
  plugins: [
    require('autoprefixer'),
    require('postcss-preset-env')({
      stage: 3,
      features: {
        'nesting-rules': true
      }
    }),
    require('cssnano')({
      preset: 'default'
    })
  ]
};

2. Stylelint

{
  "extends": "stylelint-config-standard",
  "rules": {
    "color-hex-length": "short",
    "declaration-block-no-duplicate-properties": true,
    "max-nesting-depth": 3
  }
}

.button {
  background: var(--primary);
  padding: 12px 24px;
}
