Discover What’s New in CSS 4
CSS 3 is still slowly making its way onto the web, but the World Wide Web Consortium (W3C), the governing body that oversees the development of web standards, is already plotting the future of CSS with CSS 4. The W3C recently released the first draft of CSS 4 adding dozens of new rules to make web developer’s lives easier.
The CSS 4 spec is brand new and no web browser actually supports any of these rules yet, but if you’re curious what the next few years will mean for CSS, the first draft offers a sneak peek at what’s in store for web developers.
The biggest news in the current draft of CSS 4 is support for the much-requested parent or “subject” selector. In CSS rules are typically applied to the innermost selected element. That is, given the chain body header h1, the actual CSS rule will be applied to the h1 element at the end of the chain. CSS 3 offers no way to, say, style the header tag but only if it has an h1 child element. CSS 4 changes that.
