Hello farrhad. The rounded corner effect is exactly as stated above with a few extra details… I created an image in photoshop and set it for the background of .box in the style sheet. The image is very tall (like 5000px if I remember correctly). To get the rounded bottom I added a new div with class .box-bttom and added it after .box in 2-blog.php, 404.php, archive.php, archives.php, author.php, imagegallery.php, page.php, search.php, sitemap.php, featured.php, stdblog.php and 1-defualt.php.
Admittedly, The tall image may not be the best option for achieving this effect, but it serves its purpose for the time being.
Also, as you know, this is an edited copy of the Fresh News theme.
