Our website provided a free download of ReloadCSS 1.0 for Mac. The program is included in Internet & Network Tools.
From the developer:
ReloadCSS is a simple Safari Extension that adds a toolbar button that allows you to quickly reload your stylesheets without reloading the whole page. I'm a Web developer, and I often find myself working on the CSS for forms or ajax-loaded content, and I don't want to actually have to reload the whole page, re-enter form content, etc., just to see the new styles. If that sounds familiar, then download ReloadCSS and enjoy.
