> and you can resize and position them as you like without interfering with me
Does this resize the window only locally, like scaling a video? If somebody shared a browser window with me demonstrating a responsive web site, could I drag the bottom right corner of the window around to see how the site reflows?
Yes, you're pretty much scaling the video while retaining its aspect ratio. We're doing that so users can't interfere with each other's setup (it was different early on and annoying).
