While web developers tend to focus on JavaScript and CSS, none of what we do would be possible without HTML acting as the foundation. It has long seemed like HTML wasn't evolving, but things may be changing. New elements like selectlist are on the horizon, cool new features like popovers, and a swath of related browser APIs (Web Components, PWAs, etc.).

CSS is evolving faster than ever. Flexbox, Grid, Multi-Column… To say nothing of whole new paradigms like CSS-in-JS. This is where the State of CSS survey comes in: we're taking on the world of styles and selectors to try and identify upcoming trends, and figure out what features and tools to learn next!

In this guide, Pearl Akpan analyzes the methods and properties that make user interface solutions such as infinite scrolling, animating elements on scroll, or even the popular drag and drop achievable, and afterward, dives into some practical use cases for them.

There’s a misconception that making a product accessible means sacrificing the visual design. Your UI will look too plain, they say. Your branding too dry, or too ugly.

Contrary to popular belief, the frontend scene has actually been relatively stagnant for the longest time. On a macro level, we've largely followed the same patterns and architectures with only minor variations for the past 6-7 years. This is about to change.

The logic behind Bézier Curves used in CSS animations and visual elements.

Who will design the next generation of readable, writerly web layouts? Layouts for sites that are mostly writing. Designed by people who love writing. Where text can be engaging even if it isn’t offset by art or photography. Where text is the point. With well considered flexible typesetting, modular scaling, and readable measures across a full range of proportions and devices.
