Bharat,
I use thesis Blogskin, can I use the code to change the header Ad from 468X60 to 728×90 on the header, Is that possible?
BlogSkin already got an option to display Header Ads, all you have to do is just edit custom.css file and modify CSS (increase width) of Header Ad.
tried this…but can you please tell me how to put this on the right..because it is on the left side
