Summary Don't constantly recalculate style unnecessarily if JavaScript is not enabled

Because WebKit continues parsing before it loads stylesheets WebKit tries to recalculate styles and run layouts whenever it processes a style sheet. This is only necessary so that JavaScript gets correct answers during load. When JavaScript is not enabled this is unnecessary overhead.

I think display:none has many effects that go beyond providing incorrect answers to JavaScript. But I don't have a specific example that would make this idea implausible. > WebKit tries to recalculate styles and run layouts whenever it processes a style sheet. I'm not sure if that's entirely accurate. Why would one need to force layout with document.body.offsetTop if that were so?
