New CSS features are shipping at an unprecedented rate – cascade layers, container queries, the ‘:has()’ selector, subgrid, nesting, and so much more.
It’s an exciting time, but the list can also feel overwhelming. Do I really need grids if I already know flexbox? What problem do layers actually solve? Should I rewrite my styles with each feature release, or stick with the tools that I know? It’s a good time to step back and understand how these tools fit together in a declarative system — a resilient cascade of styles.
Here’s What You Should Be Expecting:
-
Interactive live sessions
5 × 2.5h live sessions
-
Practical insights
From testing tools to integrating accessibility testing
-
Hands-on exercises
With reviews by your teacher
-
Life-time access

If you ever feel lost in the CSS weeds, wrestling with the cascade, or you just want to improve your workflow with modern, efficient, and maintainable stylesheets, then this workshop is for you! We’ll approach the language as a cohesive system, learn new features along the way, and then put it all in practice with a resilient approach to CSS architecture.
Join Miriam for a deep dive into what makes the language work, and how we can harness its power to develop resilient and delightful experiences that hold up across browsers, languages, and device interfaces.
What Will Attendees Learn In This Workshop?
- Building maintainable CSS systems with progressive enhancement.
- The entire cascade, why it exists, and what all is involved (much more than specificity!)
- Managing style conflicts with cascade layers, scope, and nesting.
- Modern selectors like :is(), :where(), and :has().
- Value resolution and validation, beyond cascading and inheritance.
- Using custom properties to build adaptive systems.
- The advantages of logical vs physical dimensions.
- The layout flow with intrinsic and extrinsic sizing.
- Size comparison functions like min(), max(), and clamp().
- When to use flexbox vs grid for layout and alignment.
- Fast and dynamic layouts using subgrid and container queries.

Who Is This For?
This workshop is intended for designers & developers with at least a basic understanding in HTML and CSS. You don’t need to be an expert to keep up, but even the experts are likely to learn something new.
What hardware/software do you need?
Bring your own laptop, your favorite text editor, and any practical CSS issues you’re facing.

Day 1 — Resilient Styles, a Declarative Cascade
8:30 AM – 9:00 AM PDT
Virtual doors open, registration, chat and introductions.
9:00 AM – 9:45 AM | First, Do No Harm
CSS is fundamentally different from other languages or design tools, built around a radical vision for contextual style and user-control. We’ll dig into the practical implications of that vision, and how the ‘grain’ of the language can guide us to more performant and resilient styles.
9:45 AM – 10:00 AM
Break
10:00 AM – 10:45 AM | Cascading & Inheritance
A deep-dive into the algorithms that take us from simple property/value declarations to a fully-styled web application. Along the way, we’ll explore new features like nesting, cascade layers, scope, and the :has() selector.
10:45 AM – 11:00 AM
Break
11:00 AM – 11:30 AM
Q&A with Mia’s on the day’s material. Networking!
Day 2 — Dynamic Systems, Custom Properties & Value Resolution
8:30 AM – 9:00 AM PDT
Virtual doors open, registration, chat and introductions.
9:00 AM – 9:45 AM | Custom Properties Reveal the Matrix
CSS custom properties (aka “variables”) expose the internals of CSS value resolution and error recovery. What does it even mean for properties to become ‘invalid at computed value time’? And how can we use these CSS internals to our advantage, developing more robust and dynamic style systems?
9:45 AM – 10:00 AM
Break
10:00 AM – 10:45 AM | CSS Variables in Practice
Practical use-cases, and interactive exercises related to CSS variables and functions…
10:45 AM – 11:00 AM

11:00 AM – 11:30 AM

Day 3 — Intrinsic Layouts, Distributing Space
8:30 AM – 9:00 AM PDT
Virtual doors open, registration, chat and introductions.
9:00 AM – 9:45 AM | Flowing & Flexing
Unlike the printed page, web content and context can be unpredictable. CSS provides tools to manage that uncertainty, aligning & distributing objects on the page. We’ll talk about normal flow, intrinsic and extrinsic sizing, logical properties, box sizing & alignment, and the flexible box model.
9:45 AM – 10:00 AM
Break
10:00 AM – 10:45 AM | Flex & Alignment in Practice
Practical use-cases, and interactive exercises related to distributing space…
10:45 AM – 11:00 AM

11:00 AM – 11:30 AM

Day 4 — Intrinsic Layouts, Defining Structure
8:30 AM – 9:00 AM PDT
Virtual doors open, registration, chat and introductions.
9:00 AM – 9:45 AM | Defining Structure
Sometimes we also need to impose external structure to create consistent and reliable layouts, even with unpredictable content. This is a full session dedicated to Grids & Sub-grids, the multiple ‘stages of squishiness’, and container queries.
9:45 AM – 10:00 AM
Break
10:00 AM – 10:45 AM | Grids & Containers in Practice
Practical use-cases, and interactive exercises related to defining layouts…
10:45 AM – 11:00 AM

Day 5 — Resilient Styles, Organizing Conventions
8:30 AM – 9:00 AM PDT
Virtual doors open, registration, chat and introductions.
9:00 AM – 9:45 AM | Cascade Aligned Programming
There are many conventions for organizing CSS, but the best systems all share underlying principles based on CSS itself. What would it mean to use The Cascade as our guide for writing maintainable CSS?
9:45 AM – 10:00 AM
Break
10:00 AM – 10:45 AM | Modern AND Resilient
CSS is designed to adapt to context – failing silently, and enhancing progressively. We have tools to manage that context and support everyone, without giving up on the latest features. The details may vary from project to project, but we’ll look at practical strategies for building an expressive and robust CSS system that works for you.
10:45 AM – 11:00 AM
