At last I paid $14.97 for CSS upgrade and tweaked the "White As Milk" theme a little last night. Play with stylesheet online is too slow so I installed XAMPP on my Windows 7 to play with it on localhost, too bad the theme available from WP dot com isn't exactly the same as that available for download for general public. The tricky part was to make my site header image clickable it's so easy if I'm allowed to add just a line in the header.php file. It's done now by a tricky and dumb way. I have yet to sort out font size and line space. I'll write to support as well as there is obviously mistake in the code for this this theme.
