Learning objectives

  • Discover the fundamentals of SASS and its installation

  • Develop reusable mixins and custom functions
  • Import modules and organize a SASS project
  • Compile SASS into optimized CSS with tools like Sass CLI

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without SASS, your CSS code explodes with repetitive lines, multiplying bugs by 3 according to Stack Overflow, you lose 40% of time on maintenance for large projects, like 20h/week for an average frontend.

  • Competitors with SASS deliver 2x faster, clients frustrated by delays, stagnant revenues at -15% for vanilla CSS devs.

  • Avoid obsolescence: 85% of modern frameworks require preprocessors, without mastery, miss out on freelance jobs at 50€/h.

  • Invest 28h to save hundreds of hours annually.

Program

Module 1Introduction to SASS: installation and variables (SCSS syntax)

Install SASS via npm, configure your development environment, create your first variables to manage colors and sizes, practice nesting to embed selectors like an HTML tree, test on a simple mockup site, produce a compiled CSS file ready for deployment, experience the power of more readable code from the first exercises.

Module 2Mixins and functions: advanced style reuse in SASS

Design mixins for responsive buttons and flexbox grids, parameterize them with arguments for maximum flexibility, integrate mathematical functions for size calculations, apply to real cases like a dynamic header, debug with watch mode, generate reusable component variants, boost your productivity by avoiding CSS repetition.

Module 3Nesting and modules: scalable SASS architecture

Structure your project into partial folders like _variables.scss and _mixins.scss, master @import and @use for modularity, manage inheritance with @extend to optimize final CSS, code a complete e-commerce layout, integrate media queries via mixins, validate multi-file compilation, build a solid foundation for complex projects.

Module 4Compilation and best practices: deploying SASS in production

Compile with Sass CLI and configure autoprefixer for browser compatibility, integrate into a Gulp or Webpack workflow, apply best practices like the 7-1 pattern, complete a final project on a real site, optimize for performance with source maps, receive your ready-to-use deliverable, leave with ready-to-use templates to accelerate future developments.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
