Fast and easy way to test your responsive design in multiple viewportsEmmet Re:View displays your responsive web-page in a number of views side-by-side so you can quickly test how web-page looks at different resolutions and devices. All views are fully synchronized: scroll, fill-in form fields, click, hover and drag elements in one view and get instant feedback in all others.

Features:

* Breakpoints View: displays resizeable view for each CSS media query breakpoint of your page. Contents of large viewports are dowscaled to fit your screen size.
* Device Wall: bird’s-eye overview of device-sized viewports. In this mode, each view is scaled according to <meta name="viewport"> tag of your page and overrides User-Agent with real device value.
* Create your own devices and presets for Device Wall.
* PageSync engine synchronizes all user interaction across all viewports: not just scrolling, form fill and clicks but also mouse hover, movement and dragging.
