Leave it to Una to give you an overview of all the Modern CSS and UI coming to your browser this year.

Everybody loves whimsical animations and interactions, which are not just cool, but actually add value. In his talk, Josh — known for his amazing explainers — will explain and show why JS frameworks like react are a surprisingly good choice.

Reflections on the past 10 years of the frontend, JavaScript, and web development. What’s changed, what’s new, and what I’m looking forward to.

Building dynamic React apps that avoid performance pitfalls can be challenging. Shaundai will show us how to optimize our components, hooks, and more.

Shaundai will also be giving a workshop on React Performance on Friday.

Native apps often feature transitions between states that both look great and help communicate the type of navigation to the user. Creating transitions between pages on the web is impossible, but even within the same page it's really hard to get right. The View Transitions API lets you create animated transitions between states without all the issues associated with keeping two DOMs alive simultaneously.

New APIs are coming to simplify this process, building on top of CSS animations and the web animation API, and it works across navigations! In his talk, Jake will explain to you how it works.

We hope you didn't make it too late last night, and you're ready for the Mystery Speaker. We are pretty sure you know the thing they are working on. ;-) Let's pump up the jam for the Mystery speaker!

Every day we have a series of choices to make. Get up early to work out or hit the snooze button? Double foam mocha latte or decaf green tea? Tabs or spaces? Our choices — even the small ones — shape our identities and help frame how we see the world.

Today we expect multiple options when choosing products and services, but then settle for subpar user interfaces and digital experiences others choose for us. While we designers and developers might have insights into what a user wants — how can anyone truly know what 7.8+ billion people prefer at any given moment?

Thankfully, we don't need to guess! In her talk, Carie will go over ways to build more inclusive user options by combining the ever-increasing power of CSS with human-focused insights of digital accessibility.

Carie will be giving a workshop on accessibility too! Learn how to build Accessible Components from Design to Development.

In his talk, Mark will explain how he approaches building good emails, while looking at accessibility, dark mode, interactivity and much more, so you'll stop worrying and start loving email.

Mark will also give a workshop on Building Semantic First HTML Emails on Tuesday.

With so many languages and frameworks available that compete for our attention, it is easy to feel overwhelmed sometimes by the next update/big thing. But it does not have to be that way. In her talk, Lydia Halley will show Next.js 13 in action, and show how easy and versatile it is, while staying performant.

One of the most important performance metrics we have for determining how quickly we get meaningful content onto the screen for our site's visitors is the Largest Contentful Paint. Improving this metric, as it turns out, goes hand in hand with understanding image loading — just under 75% of all Largest Contentful Paint’s are triggered by images or background images, and the way those images are loaded has a dramatic impact.

Let’s talk about how browsers load images today, common approaches that are slowing us down today, the techniques we have to make things faster and what we can do to make sure that we’re not just optimizing for a single browser engine along the way.

Have you ever wondered what managers do all day beyond attending meetings and writing emails? In this light-hearted talk, we'll be pulling back the curtain to explore the role and responsibilities of software engineering managers both within their teams and across the business.

We'll dive into how managers approach important aspects like project management, prioritization, and team growth. By gaining a better understanding of their perspective and learning how they think, you'll be equipped to build a strong, collaborative relationship with your own manager.
