Course overview

Many new and improved features have landed in CSS over the past few years, and a cross-browser effort to improve compatibility has made the language more stable than ever! Let’s review these enhancements to layout, responsive design, element styling, properties, and selectors, and also peek at upcoming features.

The coordinated implementation of new features across browsers these days means we can start using them as soon as they appear, which is great for keeping our stylesheets as simple as possible. A few single-line properties can now replace multiline, hacky solutions. In some cases, newly available features may even allow us to remove JavaScript workarounds we once needed to bypass old limitations!

The CSS Working Group (CSSWG)—the body responsible for updates to the language—has been taking feedback from developers and drawing inspiration from community solutions.
