So, nowdays I'm using less.css when designing websites, could never go back to standard CSS.

usually i convert the less-css to standard css before I upload it. But on my new site ( I didn't , is there any negative stuff with doing this, except people that have JS turned off (who has that anyway?) can't watch the page as it is supposed to look?

I noticed the first time i tried loading my new site in safari, firefox and chrome, the style didn't load, I had to refresh the site one time before it did, does that have anything to do with me using JS to process?
