Honestly, I don't know. At least not w/o reading findNextLineBreak. It's not a part of the code I've had to look into in great detail yet.
You can ask on #webkit, but it's better if you just read the source yourself: http://trac.webkit.org/browser/trunk/Source/WebCore/rendering/RenderBlockLineLayout.cpp#L1676 -eric On Wed, Apr 20, 2011 at 11:13 AM, Soheil Servati Beiragh <[email protected] > wrote: > Ok Eric but Can you also tell me in brief how it decides to go to the next > line?
