Pop-ups: They're making a resurgence! | Blog | Chrome for Developers

The goal of the Open UI initiative is to make it easier for developers to make great user experiences. To do this, we are trying to tackle the more problematic patterns that developers face. We can do this by providing better platform built-in APIs and components. One such problem area is pop-ups, described in Open UI as "Popovers". Popovers have had a rather polarizing reputation for a long time.
