About hover

CSS is the often unsung hero of Web development. For nearly quarter of a century it's added color, typography, layout, and more to the web. In that time it's gone from a straightforward language, to a complex set of capabilities, quite a few of which are little understood.

Many web development conferences cover CSS as part of a mix. But few are really dedicated to the langage alone. Hover will be exclusively focused on CSS–the conference CSS deserves.

Who's it for?

If you build front ends, hover is for you.

In depth knowledge

All Web Directions conferences feature in-depth knowledge from real world experts. Some you'll know, many you won't, but all bring a world of experience and knowledge.

speakers and audience
  • 12+ Transformational speakers
  • 8+ Hours of content
  • 2 Deep sessions

Your Convenor

We've invited Hui Jin Chen, CSS Working Group member, and well known author, and speaker on all things front end to help curate and MC Hover. Hui Jing brings her up to date knowledge of CSS to help shape the program.

But we're no CSS slouches either–Web Direction's founder John Allsopp was one of the original CSS Samurai. He developed one of the earliest CSS editors, Style Master, has written countless articles, tutorials, courses and even books on CSS going back almost the entire history of CSS.


Extraordinary speakers

We're assembling a world–class lineup of experts for you, going in-depth on CSS.

The New CSS Logical Properties

Most of us developers used to think in terms of left and right, top and bottom. This is because, in the early days of the internet, it was meant mostly for uploading documents, and not for the complex website structures we know today.

This is the reason that no one considered the needs of multiple language websites.

But now the new logical properties give us a lot more power to control our websites, no matter which type of language we are using, for example, English, Arabic, Japanese, etc.). All this with minimal styles changing.

Neurodiversity (and why you hate CSS)

Let's face it: you hate CSS, and it seems to hate you too. But what if this was not caused by the quirks of the language, but the very structure of our brains?

In this talk, I'll dive into how the process of “thinking” works differently among individuals, how the Multiple Intelligences Theory can explain why CSS seems alien to both designers and developers, and what can we do to make it "click" in place

Container Queries & The Future of CSS

Over the last decade Object-Oriented & Responsive design have become the norm – with tools like Flexbox, Grid, intrinsic sizing, and aspect-ratio giving us even more layout control. CSS has always been designed for a responsive web, but that goalpost can shift over time. Now several new CSS proposals like Container Queries, Cascade Layers, Scoped Styles, and Nesting are all aimed at improving the way we write responsive components and design systems.

Typography superpower with variable fonts and CSS

Over the years, there has been a lot of effort in getting typography on the web right. With the advent of variable fonts, we're already witnessing how it improves the experience and even web performance.

We'll explore how adding modern CSS capabilities such as layout grids and custom properties in the mix truly gives us superpowers to create practical dynamic type systems that are accessible, performant and works across various screen dimensions.

Understanding display

CSS Layout is all about boxes. We know that some boxes are blocks, and others are inline, and we can change the display type of elements by changing the value of the display property. That property holds the key to much more than this, however. It is the foundation on which all layout is built; the core of the inbuilt CSS layout system. Learning Grid Layout, or Flexbox, without understanding Display, leaves you with a wobbly foundation and more questions than answers.

The real question isn’t “Should I use Grid or Flexbox?” but instead, “How do I want these boxes to behave?” Understanding the interaction between layout methods will enable you to easily create fallbacks for older browsers, and be able to make more informed decisions when deciding how to build any part of your design, big or small.

CSS Variables for Real Life

CSS Variables is still a bit of a buzz word. Many of us have googled it, looked at some examples, maybe even done a tutorial, but how many of us have used CSS Variables in production?

I want to show you how and why we used CSS Variables in production in the new deployments view in Jira. More importantly I want to show you how to spot a potential use case for CSS Variables so you're ready for it when it's staring you in the face! Oh, and our use case is not dark mode or theming!

Move over TypeScript, here comes TypedCSS!

Have you ever wondered how a browser makes sense of CSS properties and values?

Turns out by parsing strings. Everything is a string: 50%, string. 2px, string. 0.5, string. #FFF, string.

So what happens when the browser can't work out what the string is? Such as "width: 24asd;"

It fails silently, warning us with the generic "invalid property value" message. But what if we could assign types to the values? So the browser knew what it was expecting and what was wrong with the value we entered.

This is where the CSS Typed Object Model comes in. It sits under the umbrella of the CSS Houdini API's and assign types to CSS values. So the browser knows it's expecting a number, colour or keyword. This allows for more control over attributes and for more useful errors.

In this talk I'm going to take you through the CSS Typed OM and examples of how we can start using and benefiting from TypedCSS.

CSS Aspect Ratio

Have you needed to maintain an aspect ratio in a layout? Perhaps 16:9 for a video or a 4:3 photograph. Was it more work than you would have thought? There’s JavaScript solutions or the Padding-Top hack that work, but there are sacrifices to these workarounds.

The frustration of maintaining a consistent width-height ratio is about to be solved with modern browsers supporting the CSS Aspect Ratio property. In this talk we look at what aspect ratio is, how we can use it in our code and the problems it’ll solve.

Responsive design turned 10 years old last year. Since then browser capabilities have changed a lot, and they're set to change even more. We'll explore new and upcoming media queries that will let website authors make websites that respond not just to screen sizes, but to many different user preferences and situations. Learn how to implement these in forward compatible ways with practical tips and examples.

Re-imagined as remote-only

In response to the unique challenges of COVID-19 we transformed our conferences into remote only events. But we wanted to go way beyond what most online events delvier.

Building on the extensive work we've done with our conference presentation platform Conffab, our conferences have been re-imagined from the ground up the conference experience, not just ports of traditional conferences to the Web.

With a focus on highly engaging, expertly filmed and edited, screen-oriented presentations, alongside spaces to connect, communicate and keep in touch with everything around the conference, you'll be immersed as if you were there–maybe even more so.

How is hover held?

Most online conferences run just like in-person conferences–one or two jam-packed days, of live streamed presentation. But with so many folks working remotely, and spending so much of their day in front of a screen we felt it was imperative to rethink this, and do something differently.

hover takes place over 2 consecutive Fridays in April 2021. It will run for 3 and a half hours each session (with a bit of downtime built-in). Plus will run it 3 times so wherever you are in the world, you can participate along with your peers, from the comfort of your own home (or maybe office).

Diversity Scholarships

We have diversity scholarships available for all our events. These provide full attendance just like any other attendee. We don't draw attention to those who have received a scholarship, but do look to make connections between them, and with our diversity sponsors, to help ensure the most valuable possible experience.

Our Scholarships focus on people who are unemployed, under-employed, self employed or in the early stages (up to 3 years) of their careers who identify as belonging to a group or groups under-represented at events like ours, and who might otherwise find it difficult to afford to attend.
