Killer Responsive Layouts With CSS Regions

As Web designers, we are largely constrained by the layout features available to us. Content placed inside a container will often naturally extend the container vertically, wrapping the content. If a design requires elements to remain a certain height, then our options are limited. In these cases, we can only add a scroll bar or hide the overflow. The CSS Regions specification provides a new option.

Regions are a new part of the CSS specification, so not all browsers have implemented them, and in some cases you might have to enable a flag to use them. They have recently gained support in iOS7 and Safari 7, as well as Safari 6.1+. Adobe maintains a list of supported browsers and instructions on enabling regions and other features. However, support for regions is constantly growing. For a robust list of which browsers have implemented regions and the various features available, see Adobe’s “CSS Regions Support” page.
