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 this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1SASS Fundamentals: Variables, Nesting, and Operations (VS Code, Compilers)
Dive into SASS variables to centralize colors and sizes, chain with nesting to structure your selectors, practice arithmetic operations on concrete responsive layout exercises, compile in real-time with Dart Sass, produce your first optimized CSS files, and measure gains in readability.
Module 2Mixins and Functions: Reuse and Customization (Modular Exercises)
Create parameterized mixins for buttons and flexbox grids, test them on real e-commerce site cases, develop custom functions for rem/em calculations, apply them to reusable components, debug with sourcemaps, export production-ready deliverables, and gain immediate productivity.
Module 3Modules and Imports: Scalable Architecture (Multi-File Project)
Organize your code into modules like _base.scss and _components.scss, master @import and @use to avoid duplicates, build a complete dashboard project with modular structure, optimize partial compilation, integrate with Gulp, validate scalability through collaborative exercises, and prepare solid foundations for teams.
Module 4Advanced Directives: @extend, Loops, and Conditionals (Automation)
Leverage @extend for selective inheritance without CSS bloat, implement @each and @for to generate dynamic grids and animations, add @if for day/night theme variants, apply to a real landing page case, analyze code reduction up to 40%, and produce compact, high-performance outputs.
Module 5Best Practices and Integration: Final Project (Professional Workflow, Deployment)
Review common pitfalls and SASS best practices, integrate with Webpack or Laravel Mix on a real e-commerce project, test cross-browser compatibility, measure performance with Lighthouse, finalize a deliverable portfolio, receive personalized feedback, and leave with ready-to-use templates to boost your projects immediately.

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.
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.
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.
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.
