It was suggested I create a bookmarklet for this site, http://lab.maltewassermann.com/viewport-resizer/
The goal is for this to be a tool I can click on in safari while working on beta responsive sites to quickly see how they respond. However, I can't figure out how to do this. I can save it as a bookmark (not bookmarklet) but that doesn't do me any good because when I go to another website, I lose this bookmark. Hence, the need for a bookmarklet. Any ideas?
