PX to VW Converter

The best way to build a responsive site is through variable sized content. If a designer presents you with a layout that looks good in only one viewport, use this to convert fixed elements like px, pt and cm units into variable widths that combine the size with the intended viewport that said element was sized for. Dump in your CSS and will return the stylesheet with all of your fixed references re-done as variable sizes that match the original design intent.
