The web platform has leveled up significantly in the past few months. There are so many powerful new CSS and UI capabilities at your fingertips that you might not even know about that can reduce your script payload and make your life a lot easier. This talk covers some of the new landings in the native web space space, such as powerful new selectors, container queries, experimental native UI components (and more) to improve your developer experience.

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.

After many twists, turns, and evolutions of the web in the past 10 years, Lee is more optimistic than ever about its future. In his talk, he'll share why and hopefully convince you the same.

It's easier to make a fast website than it is to keep a website fast. If you've invested countless hours in speeding up your pages, but you're not using performance budgets to prevent regressions, you could be at risk of wasting all your efforts.

In this session, we'll cover how to:

• Understand the difference between performance budgets and performance goals
• Identify which metrics to track
• Validate your metrics to make sure they're measuring what you think they are – and to see how they correlate with your user experience and business metrics
• Determine your budget thresholds
• Get buy-in from different stakeholders in your organization
• Integrate with your CI/CD process
• Maintain your budgets so you stay fast!

Container Queries allow us to measure (or ‘query’) aspects of a ‘container’ element, and style any descendants based on the query result. Miriam will convince you why this is so incredibly cool, and how you will be able to use this in your websites.

Enhance a site without page transitions, into one that does, with View Transitions. With this API, we're able to animate between two states of a document, including full page navigations.

Join Adam as he guides you through the process of incorporating View Transitions into his blog nerdy.dev, with easy-to-follow steps that you can apply to your own projects too!

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.

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.
