In my style.css:
Line 1-4 fix this bug.
Line 5-20 can reduce three times of HTTP requests.
Line 21-23 can make perfect gaps between posts in both Safari/Webkit and Firefox. This image shows the differences.
Line 24-26 hide the “Search for:” label in sidebar. There’s not enough space to display this label.
Line 27-32 fix this bug on the footer and the gap around the text looks more nice.
In my additional stylesheet style-iphone.css for iPhone, the styles fix the bug on the right border of the page and the gap between header and wrapper (image with notes).
Thanks for your concern.
